Wake Industrial LLC is not an authorized distributor of this product.
The B & R Automation 2PS425.9 is part of the System 2010 Controllers series and operates with a nominal input voltage of 24 VDC, supporting a maximum input voltage of 30 VDC and a minimum of 18 VDC. It delivers an output power of 100 W at 24 VDC, and has a backup capacitance of 20000 microfarads for single-phase and 12000 microfarads for three-phase. The controller measures 285 mm in height, 40 mm in width, and 185 mm in depth.
Internal Product Review
The 2PS425.9 is a B & R Automation System 2010 controller power supply with 24 VDC nominal input and 100 W output power. Backup performance is especially strong, with 20000 µF capacitance on 1-phase operation and 12000 µF on 3-phase operation. A wide 18 to 30 VDC input range makes this unit a dependable choice for stable industrial control power.

Product Description:
The 2PS425.9 power supply module is manufactured by B&R Automation and belongs to the System 2010 Controllers series. Designed for cabinet installation next to CPU and I/O cards, it converts incoming low-voltage DC power and stabilizes it for control electronics and field transducers. By providing regulated energy and status signaling, the unit supports continuous operation of industrial motion, safety, and process sequences even during short supply dips. It also provides a ready relay that allows PLC logic to verify the module’s internal status before the machine starts.
Input requirements range from 18 to 30 VDC, with a nominal value of 24 VDC. When the supply reaches the upper limit, the device draws no more than 6.5 A, and its internal conversion stage delivers up to 100 W of usable power at a regulated 24 VDC output. Overcurrent protection is provided by a replaceable 10 A, 250 V slow-blow fuse. The housing is only 40 mm wide, extends 185 mm into the enclosure, and rises to 285 mm high. This narrow profile lets multiple System 2010 modules share the same DIN rail while keeping wiring runs short. These dimensions also help preserve space for adjacent controllers and connection terminals inside the cabinet.
During a supply interruption, the module keeps the 24-volt bus active with storage capacitors rated at 20,000 µF for single-phase inputs and 12,000 µF when powered from a three-phase buffer rail. A normally open ready contact reports internal voltage stability; it can switch loads up to 2 A and withstand transients of 2.5 kV across the contact gap. The relay accepts monitoring circuits operating at 24 VDC or 230 VAC, so it can signal either low-voltage PLC inputs or higher-voltage control lamps. With a minimum input threshold of 18 VDC, a maximum input of 30 VDC, and an output connected directly to the 24 VDC control bus, the module supports common plant battery backups and DC power trunks without additional converters.
