PULS CP20.241-R2 DIN-rail redundantiemodule 24V 20A 480W

With a 25 mV voltage drop at 10 A per channel, the PULS CP20.241-R2 keeps efficiency high while providing active MOSFET-based redundancy for 24 VDC systems.

Overview

The CP20.241-R2 is a DIN-rail mountable redundancy module that combines two 24 VDC power supply inputs into a single output, ensuring continuous operation if one supply fails. It supports 1+1 and N+M redundancy configurations and delivers up to 20 A output current.

What stands out

• Active redundancy using MOSFETs for minimal power loss (3.2 W at 20 A output)
• Two inputs, each rated up to 20 A, with DC-OK signaling for each input
• Wide operating temperature range from -40°C to +70°C
• Metal housing for durability in industrial environments

Technical details

• Input: 2 x 24 VDC (max 20 A each)
• Output: 24 VDC, max 20 A
• Voltage drop: 25 mV at 10 A per channel
• Power loss: 3.2 W at 20 A output
• Protection: reverse input voltage protection
• Mounting: DIN rail

Our verdict

A reliable choice for critical 24 VDC systems requiring hot-swap redundancy without significant efficiency loss.
