The power supply redundancy modules are used to reliably and safely connect power supplies without protection diodes together in parallel or redundant operation. These power supply redundancy modules will work with 12 volt, 24 volt or 48volt DC power supplies. The 3 models of parallel connection power supply modules are for power supplies up to 15, 20 or 50 amps. The XCSBD is a low cost basic power supply redundancy module that mounts on the standard 35mm DIN rail. It is user settable for 12-24 or 48Vdc and has a max rating of 15 amps.
The OR20 din rail power supply redundancy module has an input rating of 12-85Vdc and can work with power supplies up to 20 amps. In addition to pluggable connections for easy wiring this din rail power supply redundancy module has input protection, LED status indicators, an alarm contact and an operating temperature of 70 degree C with no derating.
The OR50 is a UL Listed DIN rail power supply redundancy module with premium features for use in critical applications where capability and reliability are extremely important. This ultra-compact power supply redundancy module is microprocessor controlled, has an output of 50 amps, a wide range input of 12-85Vdc and a color bar graph display that shows if the power supplies are balanced. It has 3 LED status indicators and 2 alarm contacts for remote monitoring. The current share bar graph display makes it easy to see if one of the two power supplies is running into issues thereby allowing for you to take preventive steps.
