DC Solid State Relay 100amps
Solid State Relay 3-32VDC
Input 100A@30VDC Switching
Switching high current DC loads
normally requires use of a contactor to avoid arcing as the contacts
try to separate. DC pulls a long flame unlike AC which breaks
every cycle.
These solid state relays use
MOSFET technology to provide an economical and reliable method
of switching medium to high power DC loads.
By electrical switching with
a semiconductor, there is no arcing as contacts break at high
current and the low on-state resistance provides a viable alternative
to the bulky and expensive contactors we used to use.
These units are also isolate
the control side from the switch side with a 2500VRMS LED light
pathway.
You can parallel these units
also for higher current switching. If you do, overdrive the input,
to get the fastest switch time.
Output Circuit
Load Voltage: 0-30VDC

spikes
We suggest mounting on a heat
sink or steel cabinet back wall for dissipating heat up to 35
watts at full load. We can supply tunnels or open fin heat sinks.
You also may need a fan if the
load stays that high for some time.
Use a thermal switch on the heatsink
to control the fan.
