Description
The 0RHB-Q2T53x is isolated DC/DC converters that operate from a nominal 48 Vdc source. These units will
provide up to 424W 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 input undervoltage lockout. This converter
is provided in an industry standard half- brick package.

Note: 1.When Remote On/Off pin is open, for active low option, unit is off; for active high option, unit is on.
2. The efficiency is measured at Vin=48V, full load and Ta=25°C.
3.Test the temperature of baseplate.
4. All specifications are typical at nominal input, full load at 25°C unless noted.

Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim pin and the
Vout. Only one of the resistors should be used for any given application.
