Description
The FHS Series power modules are dc-dc converters that operate over an input voltage range of 36 to 75VDC and
provide a regulated DC output voltage at up to 18 amps of output current. The output is fully isolated from the
input, which allows a positive or negative output configuration.
The open-frame module is constructed with a two-board approach.
The power devices are connected to an
Insulated Metal Substrate (IMS) base plate, which provides very low thermal impedance. A separate PCB is
populated with the control circuitry and is physically isolated from the hotter IMS board. This approach allows for
lower component temperatures, hence increased reliability.
The standard feature set includes remote on/off,
remote output voltage sensing, negative logic output trim (optional positive logic output trim available
1), input under
and overvoltage lockout and overtemperature shutdown with hysteresis.
