The ERM rectifier modules are designed and optimised for demanding telecom and industry applications. The convection cooled ERM 48/60-300 rectifier is a building block of the EPOS Mini power systems. The rectifier provides 300 W output power at 48 VDC or 60 VDC, with a single phase, semi-wide input voltage range. The rectifier may be operated either with a system controller or as stand-alone modules, with or without parallel-connected batteries. Through the system bus connection settings and data on input and output voltage and current, unit status, inventory information and operational parameters is provided.
