RSD-40A Diode Module
with Alarms
NEW
The RSD-40A modules can be used to
parallel two power supplies or isolate a single supply using diodes. The parallel version
works with two power supplies rated up to
20A each. The single diode isolation version
is rated up to 40A.
The low-voltage drop Schottky diodes are
mounted on a fan-cooled heatsink. The fan
starts only when the heatsink temperature
exceeds 60 deg. C and features proportional control to extend the operating life. The
temperature of the heatsink is monitored
and an analog output proportional to temperature and a high-temperature alarm output are provided. Terminals are also provided to monitor the presence of input voltage(s) and an output voltage.
Multiple output terminals are provided to
make power distribution easier.
