Description Product Introduction The ABB UNS2980C-ZV4 is the power supply module for the AC 800PEC platform—the high-performance controller ABB uses for demanding drive and motion control applications. This module slides into the PEC chassis, providing clean, regulated 24 VDC power to the CPU, I/O modules, and communication interfaces. It’s the foundation that keeps the controller running in applications like winders, extruders, and high-speed presses. What separates the ABB UNS2980C-ZV4 from the earlier UNS2980B is current capacity and input filtering. The “C” revision delivers 10 A continuous—up from 8 A on the B revision. That extra headroom matters when you have a fully loaded PEC chassis with multiple high-speed I/O modules and communication links. The ZV4 suffix indicates the final hardware revision with improved transient protection and a more robust input stage. In my experience, the earlier B revision was prone to nuisance trips if the incoming 24 VDC supply had voltage dips during large motor starts. The C revision rides through those dips without blinking. ABB UNS2980C-ZV4 Key Technical Specifications Parameter Specification Model ABB UNS2980C-ZV4 Series AC 800PEC Input Voltage 24 VDC (18–32 VDC range) Output Voltage 24 VDC (regulated, isolated) Output Current 10 A continuous (12 A peak) Efficiency > 88% Protection Overcurrent, short-circuit, over-temperature, reverse polarity Isolation 1500 VAC between input and output Status Indication LED for power OK, LED for output fault, LED for overload Mounting AC 800PEC chassis (PEC80/PEC90 rack) Cooling Convection-cooled (no fan) Operating Temp -25°C to 70°C Redundancy Supports parallel operation for N 1 redundancy Dimensions Fits one PEC chassis slot Firmware / Software Versions & Upgrade Notes The ABB UNS2980C-ZV4 contains no firmware or software. It is a pure power supply with no digital components. No configuration, no programming, no firmware upgrades. Installation: Slots into the designated power supply position in the PEC chassis. The AC 800PEC chassis typically has two power supply slots for redundancy. Redundancy: You can install two UNS2980C-ZV4 modules in the same chassis. They share the load automatically through internal OR-ing diodes. If one fails, the other takes the full load with no interruption. No external redundancy module is required. Field note: The ABB UNS2980C-ZV4 has internal input fuses. They are not user-replaceable. If you apply reverse polarity or overvoltage, you’ll need to replace the entire module. Check your wiring twice before powering up. ABB UNS2980C-ZV4 Compatibility & Replacement Matrix Original Model Replacement Model Compatibility Level Key Notes ABB UNS2980B (8 A) ABB UNS2980C-ZV4 (10 A) Drop-in Same mounting, same connectors. The C revision has higher current capacity. No wiring changes. ABB UNS2980A (original) ABB UNS2980C-ZV4 Drop-in Direct upgrade. The A revision had 6 A capacity and no reverse polarity protection. ABB UNS2980C-ZV4 (same) ABB UNS2980C-ZV4 Drop-in Direct replacement. Any ZV4 revision is interchangeable. ABB UNS2980C-ZV3 (different variant) ABB UNS2980C-ZV4 Drop-in ZV3 has slightly different input transient ratings. ZV4 is the preferred replacement. Third-party 24 VDC supply ABB UNS2980C-ZV4 Incompatible The PEC chassis requires the power supply to mate with the backplane connector. A DIN-rail supply cannot substitute. Frequently Asked Questions Q: What chassis does this power supply fit? The ABB UNS2980C-ZV4 fits the AC 800PEC chassis—specifically the PEC80 and PEC90 racks. It does not fit S800 I/O racks, AC 800M racks, or Advant chassis. The PEC chassis has a dedicated power supply slot with a keyed connector. Q: Can I use two UNS2980C-ZV4 modules in the same chassis? Yes. The PEC chassis has two power supply slots for redundancy. Install two modules. They automatically share the load. If one fails, the other supplies the full 10 A. The controller keeps running—no interruption. Q: My module shows a red FAULT LED. What do I do? A red FAULT LED on the indicates an output overload or short circuit. Check the total current draw of all modules in the chassis. If it exceeds 10 A, you need to reduce the load or add a second power supply. If the load is within spec, power down the chassis, remove the module, and check for shorts on the backplane pins. Q: What input voltage range does this module accept? The accepts 18–32 VDC. The nominal input is 24 VDC. Do not apply AC voltage—it will destroy the input stage immediately. If your plant has 120 VAC or 230 VAC control power, you need a separate AC-to-DC power supply feeding this module. Q: Can I hot-swap this module? No. The AC 800PEC chassis does not support hot-swapping power supplies. Power down the entire chassis before removing or inserting the . The backplane connectors are not designed for live insertion. Q: What’s the difference between UNS2980C-ZV4 and UNS2980C-ZV3? The ZV4 revision has improved input transient protection and slightly higher efficiency. Electrically, they are compatible. The ZV3 is an earlier version. If you’re replacing a ZV3, the ZV4 is the direct drop-in replacement. Q: How do I calculate if 10 A is enough for my chassis? Add up the power consumption of every module in the PEC chassis. The CPU (PPC902 or similar) draws about 3–4 A. Each I/O module (like CRBX01) draws 1–2 A. Communication modules draw 0.5–1 A. A fully loaded PEC chassis can draw 8–9 A. The at 10 A gives you about 10% headroom. If you’re over 9 A, add a second power supply. Q: My controller randomly resets. Could the power supply be the problem? Yes. If the is failing, it can cause brownouts that trigger the controller’s watchdog. Check the status LEDs. If the power OK LED is flickering or the fault LED comes on intermittently, replace the power supply. Also verify the input voltage—if it’s dropping below 18 V during motor starts, the power supply will shut down.
