The customer challenge: resets, dips, and an oversized UPS quote<\/h2>\n<p>The customer operated three automated assembly lines fed from a utility connection shared with a resistance welding area. Voltage dips of 100\u2013300 ms were occurring several times per week, and the depth reached 55\u201365% of nominal. The PLCs were resetting, the industrial PCs were rebooting, and the HMIs were losing communication. Each event cost between 20 and 90 minutes of lost production plus scrap.<\/p>\n<p>The first proposal from a UPS vendor was a plant-wide system sized for the entire facility load: drives, heaters, conveyors, and lighting included. The quotation was technically correct and commercially unworkable. It required a dedicated battery room, a reinforced floor, additional ventilation, and a capital commitment several times the annual cost of the downtime it would prevent.<\/p>\n<p>The procurement team asked a different question: which loads actually need to ride through the dip, and for how long? That question reframed the project from \u201cbuy a bigger UPS\u201d to \u201cdefine the ride-through requirement per load group\u201d \u2014 the scope TPS was engaged to deliver.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-19056\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/10\/PLC-Voltage-Dip-Protection-Control-Cabinet-Backup-1.jpg\" alt=\"PLC Voltage Dip Protection Control Cabinet Backup\" width=\"1920\" height=\"1079\" \/><\/p>\n<\/section>\n<section id=\"why-oversizing-fails\">\n<h2>2. Why plant-wide UPS oversizing is the wrong answer<\/h2>\n<p>A plant-wide UPS is the right architecture when the process cannot tolerate any interruption and the load is homogeneous. In a machine-building plant with mixed loads, it usually produces three avoidable problems.<\/p>\n<h3 id=\"runtime-mismatch\">2.1 Runtime mismatch and cost per protected kilowatt<\/h3>\n<p>The PLC, the industrial PC, and the network switch need to ride through a 300 ms dip and, in the worst case, complete a controlled shutdown over 2\u20135 minutes. The drives and heaters need nothing of the kind \u2014 they can drop and restart. Sizing a single UPS for the sum of all loads means paying for battery capacity and conversion hardware that protects loads which do not need protection.<\/p>\n<p>The cost per protected kilowatt therefore rises sharply with the size of the UPS, while the benefit stays concentrated in a small group of loads. Segmenting the load reverses that ratio.<\/p>\n<h3 id=\"single-point\">2.2 The single-point-of-failure problem<\/h3>\n<p>A plant-wide UPS concentrates the continuity of the entire facility in one asset. A battery string failure, a bypass event, or a maintenance window affects every line at once. Distributed panel-level backup keeps the failure domains small: one panel\u2019s backup module failing affects one line, not the plant.<\/p>\n<p>There is also a practical maintenance argument. Panel-level 24V DC backup modules are replaced in minutes by a maintenance technician. A plant-wide UPS battery bank is a planned outage.<\/p>\n<p><a class=\"cta-primary\" href=\"https:\/\/tps-elektronik.com\/en\/services\/additional-services\/\">Explore TPS additional services \u2192<\/a><\/p>\n<\/section>\n<section id=\"tps-approach\">\n<h2>3. The TPS approach: segmented ride-through instead of plant-wide backup<\/h2>\n<p>TPS did not manufacture the backup modules. The scope was to define the requirement, specify and source the modules, integrate them into the control panels, and validate the result against measured dip profiles. That integration role is the core of TPS\u2019s <a href=\"https:\/\/tps-elektronik.com\/en\/comprehensive-electronic-design-services-complete-solutions\/\">comprehensive electronic design and integration services<\/a>.<\/p>\n<h3 id=\"load-map\">3.1 Step 1 \u2014 Load mapping and ride-through requirements<\/h3>\n<p>The first deliverable was a load map, not a product list. Every load in the three lines was classified into three groups:<\/p>\n<ul>\n<li><strong>Critical<\/strong>: PLC CPU, safety controller, network switch. Requirement: ride through 300 ms and remain in run state.<\/li>\n<li><strong>Ride-through with controlled shutdown<\/strong>: industrial PC and HMI. Requirement: ride through 300 ms, then execute a defined shutdown sequence within 3 minutes.<\/li>\n<li><strong>Non-critical<\/strong>: drives, heaters, conveyors, lighting. Requirement: none. Allowed to drop and restart under the line\u2019s existing restart procedure.<\/li>\n<\/ul>\n<p>The classification was agreed with the customer\u2019s engineering and operations teams, because it defines what the line will and will not do during a dip. That agreement is the part that prevents later scope creep.<\/p>\n<h3 id=\"panel-backup\">3.2 Step 2 \u2014 Panel-level 24V DC backup and DC-input IPC<\/h3>\n<p>For the critical group, TPS integrated a 24V DC backup module into each control panel, sized from the measured PLC and network load plus the hold-up requirement. The module maintains the 24V rail during the dip and switches back automatically on recovery.<\/p>\n<p>For the industrial PC, TPS specified a DC-input unit rather than an AC-input PC behind a small UPS. This removes one conversion stage, reduces the panel footprint, and gives the shutdown software a direct view of the DC rail voltage. The PC\u2019s shutdown sequence is triggered by the backup module\u2019s status contact, not by a separate UPS interface.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-19051\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/10\/Voltage-Sag-Ride-Through-UPS-PLC-Control-Bus-2.jpg\" alt=\"Voltage Sag Ride Through UPS PLC Control Bus\" width=\"1920\" height=\"1079\" \/><\/p>\n<p>For panels where a panel-level AC UPS was already installed, TPS kept it and re-scoped it to the critical group only, which reduced the required VA rating and allowed the existing unit to be retained instead of replaced.<\/p>\n<h3 id=\"validation\">3.3 Step 3 \u2014 Dip injection and validation<\/h3>\n<p>Validation used a programmable AC source to inject dip profiles matching the measured utility events: 60% residual voltage for 200 ms, 55% for 300 ms, and a 0% interruption for 20 ms. The PLC was monitored for run state, the IPC for reboot events, and the HMI for communication loss.<\/p>\n<p>The test also covered the recovery transition: the backup module must return to normal operation without causing a second reset, and the IPC shutdown sequence must not trigger on a dip that the PLC rode through successfully. Both behaviours were verified and documented in a test report that the customer attached to the line\u2019s technical file.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-19046\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/10\/Factory-Control-UPS-Sizing-Load-Segmentation-Map-3.jpg\" alt=\"Factory Control UPS Sizing Load Segmentation Map\" width=\"1920\" height=\"1079\" \/><\/p>\n<p><a class=\"cta-primary\" href=\"https:\/\/tps-elektronik.com\/en\/services\/additional-services\/\">Request a ride-through scope review \u2192<\/a><\/p>\n<\/section>\n<section id=\"results\">\n<h2>4. Measured results and customer outcome<\/h2>\n<p>The segmented approach delivered the continuity result without the plant-wide UPS. Measured outcomes on the three lines:<\/p>\n<ul>\n<li><strong>PLC resets during dips<\/strong>: reduced from several per week to zero across a six-month observation period covering more than 40 recorded dip events.<\/li>\n<li><strong>Industrial PC reboots<\/strong>: eliminated; the IPC now completes a controlled shutdown when the dip exceeds the ride-through window.<\/li>\n<li><strong>Protected load<\/strong>: reduced from the entire facility load to the critical and ride-through groups \u2014 a small fraction of the original plant-wide UPS rating.<\/li>\n<li><strong>Capital cost<\/strong>: the panel-level scope avoided the battery room, the floor reinforcement, and the oversized conversion hardware of the plant-wide proposal.<\/li>\n<li><strong>Maintenance<\/strong>: backup modules are replaced at panel level, with no planned plant outage.<\/li>\n<\/ul>\n<p>The customer subsequently applied the same load-map method to two additional lines. The load map and the validation report became the standard documents for new line specifications, which is the outcome that matters for procurement: a repeatable scope, not a one-off fix.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-19041\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/10\/Industrial-UPS-for-PLC-Integration-RFQ-TPS-4-1.jpg\" alt=\"Industrial UPS for PLC Integration RFQ TPS\" width=\"1920\" height=\"1079\" \/><\/p>\n<p>Related TPS additional services used in the project include <a href=\"https:\/\/tps-elektronik.com\/en\/incoming-goods-inspection-production-line-efficiency\/\">incoming goods inspection for production line efficiency<\/a> and <a href=\"https:\/\/tps-elektronik.com\/en\/inventory-management-for-electronics-component-stock\/\">inventory management for electronic components<\/a>, which kept the backup module and IPC stock aligned with the line build schedule.<\/p>\n<\/section>\n<section id=\"faq\">\n<h2>5. FAQ<\/h2>\n<div>\n<h3>Do I need a plant-wide UPS to protect PLCs from voltage dips?<\/h3>\n<div>\n<div>Usually not. Most PLC resets during short dips can be prevented by protecting the critical control loads \u2014 PLC, safety controller, network switch, and industrial PC \u2014 with panel-level backup sized for the measured dip profile. A plant-wide UPS is justified when the process cannot tolerate interruption at all and the load is homogeneous.<\/div>\n<\/div>\n<h3>How long does a PLC need to ride through a voltage dip?<\/h3>\n<div>\n<div>The requirement comes from the measured dip profile at the panel terminals, not from a standard value. For the customer in this case, 300 ms covered the recorded events. The PLC\u2019s own ride-through capability should be checked against the applicable standard, such as IEC 61131-2 and IEC 61000-4-11, but the decisive input is the site measurement.<\/div>\n<\/div>\n<h3>Is a DC-input industrial PC better than an AC PC behind a small UPS?<\/h3>\n<div>\n<div>A DC-input PC removes one AC-DC conversion stage, reduces panel footprint, and gives the shutdown software a direct view of the DC rail. It also simplifies the interface with a 24V DC backup module. An AC PC behind a small UPS remains valid where the existing PC cannot be changed, and TPS re-scopes the UPS to the critical load only.<\/div>\n<\/div>\n<h3>Does TPS manufacture the UPS or backup modules?<\/h3>\n<div>\n<div>No. TPS specifies, sources, integrates, and validates the backup modules and DC-input PCs as part of the control panel scope. This is an integration service, not a product manufacturing claim. See the <a href=\"https:\/\/tps-elektronik.com\/en\/services\/additional-services\/\">additional services page<\/a> for the scope.<\/div>\n<\/div>\n<h3>How is the ride-through result validated?<\/h3>\n<div>\n<div>With a programmable AC source that injects dip profiles matching the recorded site events \u2014 for example 60% residual voltage for 200 ms and 55% for 300 ms. The PLC run state, IPC reboot events, HMI communication, and the recovery transition are all monitored and documented in a test report.<\/div>\n<\/div>\n<\/div>\n<\/section>\n<footer
