PULS PIRD20.241 INTRODUCTION
The MLY02.100 is a simple redundant The PIRD20.241 is a redundancy module that can be used to build 1+1 and N+1 redundant systems. It is equipped with two input channels, which can be connected to power supplies with up to 10A output current, and one output, which can carry nominal currents up to 20A. The module is suitable for power supplies with constant current overload behavior as well as any kind of “hiccup” overload behavior.
The PIRD20.241 is the perfect solution to use in a redundant system if the power supply itself is equipped with a DC-OK signal. Another application for this redundancy module is to separate sensitive loads from non-sensitive loads. This avoids the distortion of the power quality for the sensitive loads, which can cause controller failures.
