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 42 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, positive logic output trim (optional negative logic output trim available), input under and
overvoltage lockout and overtemperature shutdown with hysteresis.
A microcontroller has been employed within the supervisory circuitry offering increased flexibility in the product’s
feature set. (Remote on/off logic can be selected at the time of manufacture to be either positive or negative with a
simple program change.
Similarly, overcurrent protection and output overvoltage protection functions can be
changed from the normal non-latching mode to latching mode with a simple program change. Specific changes
should be discussed with the factory.)
