DATASHEET 5184, REV. -
1200V, 50A, Solid State DC Contactor
Applications:
● Main DC Bus Switch
● DC Motor Bus Switch
● Battery Disconnect
● Bus Discharge
● DC Contactor
Description:
Sensitron has developed a small footprint High Voltage/High Current DC solid state Relay/Contactor. This
device incorporates the latest state of the art technology to reduce the “on” state power losses and voltage
drop to a minimum. The device is a true four terminal relay, not needing additional power sources for bias.
This device uses robust magnetic coupling to achieve high isolation, reliability, and long life. Unlike opto-
isolation techniques this device will not degrade with time. The input control lead will accept any voltage
from 4.6V to 36VDC.
Features:
● 2000V Input to Output Isolation
● 1200V Blocking, 50A Continues Current
● 400A Surge Capability
● -55 to 100 oC Operation
● Single wide range DC input signal 4.6V to 36V
● Low Power Control, .5W Typ.
● True Four Terminal Operation
● “On” state voltage less than 2.0V @ 50A
● Fast turn on/turn off, less than 2 us
● High Current Terminals
● Three Point Mounting Plate
