Description
The 0RCY-C0TV2x is isolated dc/dc converter that operates from a nominal 48 Vdc source. This secondary side
control unit will provide up to 60 W of output power from a nominal 48 Vdc input. Features include start-up into
pre-biased load, remote on/off, over current protection and under-voltage lockout. This converter is provided in an
industry standard eighth brick package.
