Description
The 0RCY-60U03x is part of the isolated dc/dc converters that operate from a wide input range (18 Vdc - 75 Vdc)
and can cover both 24 Vin and 48 Vin input range. These units will provide up to 49.5 W of output power. They
are designed to be highly efficient and low cost. Features include remote on/off, over current protection, over
voltage shut down, over temperature protection and under-voltage lockout. These converters are provided in an
industry standard 1/8 brick package.
