PULS UB10.245 Buffer Module 24V 10A 240W DIN Rail

In automated production lines and machine control cabinets, a brief power interruption can cause costly downtime. The PULS UB10.245 buffer module bridges short voltage dips and fluctuations on the 24V DC bus, keeping connected loads like PLCs, HMIs, and sensors running until the main supply recovers or a controlled shutdown is executed.

Why choose it

The UB10.245 requires no external batteries, using maintenance-free capacitors to deliver reliable, instant bridging. Its high efficiency and compact DIN rail housing make it easy to integrate into existing control panels without additional cooling.

Ideal use cases

• Buffering 24V DC power for PLCs and industrial PCs
• Bridging short mains interruptions in automated machinery
• Ensuring controlled shutdown of critical processes
• Stabilizing voltage in systems with fluctuating loads

Good to know

The module is designed for use with PULS 24V power supplies but works with any regulated 24V DC source. It features reverse polarity protection and over-temperature shutdown for safe operation.
