Description
The 0RCB-60T02x is isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will provide
up to 50 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and low cost.
Features include remote on/off, over current protection and under-voltage lockout. This converter is provided in
an industry standard eighth brick package.
