Description
The CPC1593 is a normally open (1-Form-A)
Solid State Relay that incorporates load current
limiting with over-voltage protection and thermal
management. This self-resetting triple protection
scheme protects not only the CPC1593’s load,
but also the CPC1593 itself, thus creating a highly
effective switching mechanism that is designed to
survive in the harshest operating environments.
Over-voltage protection is activated when the voltage
across the switch is greater than 21V and the
device is in current limit. The over-voltage protection
deactivates the switch while allowing a restricted
load current of less than 100A to fl ow. When the
voltage across the switch falls below the over-voltage
threshold, the switches reactivate. If the fault persists,
then these responses will repeat.
The CPC1593 is designed for use in AC
environments where fault conditions can persist for
long periods of time, and where, upon removal of
the fault, return to normal operation is expected. The
CPC1593 is designed to survive extended power
cross conditions.
