The input voltage range is from 9-60VDC and the output voltage (0-60V) and current (0-50A) are independently set via fixed trim resistors or an external voltage. The Ishare pin has two functions: it can be used to monitor the load current in stand-alone applications or it can be used to **Buck/Boost** connect three modules in parallel to double the maximum output current to 100A. Typical applications are 48V to 24V or 12V to 24V battery power conversion, electric vehicles, battery voltage stabilizers or **converter** high power laboratory DC power supplies. With appropriate cooling, the full power operating temperature extends from -40°C to +85°C and the RBBA3000-50 comes with RECOM’s standard 2 year warranty. ## Selection Guide Part Input Voltage Input Nom.
