About the BRU-500-PSM-50ES

The BRU-500-PSM-50ES was a Power Supply Module that was first produced by Reliance Electric. At one point, this module may have been sold by ABB or Baldor Reliance depending on what years it was in production. It is no longer supported by these companies and might be difficult to find.

The BRU-500-PSM-50ES was meant to be used with the BRU-500 series of servo or spindle drives and their motors. It had the ability to provide DC power to up to 6 drive modules. The BRU-500-PSM-50ES had an input voltage rating that was 120/240 VAC and 50/60 Hz. It had an output voltage rating that was 170/340 VAC and 0-400 Hz. It could retain a 100-amp bus. It could uphold a 5 kiloamp short circuit rating. It was a feature of the AutoMax SA-500 series of products and was 3-Phase.

The BRU-500-PSM-50ES could be mounted onto a vertical flat surface like a panel. It had factory-drilled holes that were used along with bolts and washers to secure the power supply onto the flat surface. It was important that the module be mounted in an inside environment and not directly next to other devices to prevent it from getting overheated. There were two fans on the underside of the power supply that had the ability to ensure that the internal components were provided with air circulation. On the faceplate of the power supply were a set of LED lights that were labeled phase loss, disabled, PSM ready, and overtemp. The PMS ready indicator was green while the other three were red. There was a very small terminal strip on the faceplate that was labeled TB1.
