SPDPXXD375 SERIES
DC Solid State Power Controller Module
Description:
These Solid State Power Controller (SSPC) Modules are designed to operate without any heatsink
requirements. They are microcontroller-based Solid State Relays rated up to 10A designed to be used in high
reliability 375V DC applications. These modules have integrated current sensing with no derating over the full
operating temperature range. These modules are the electronic equivalent to electromechanical circuit
breakers with isolated control and status.
This series is supplied in 2 SSPC families, with each family being programmable over a 3.3:1 current range:
SPDP03D375: Programmable from 0.9A to 3A
SPDP10D375: Programmable from 3A to 10A
This series also allows programming the Instant Trip level from 400% to 800% of maximum rating.
Battle Override Option: SPDPxxD375-B
MIL-STD-1760 Trip Curve Option: SPDPxxD375-M
Compliant Documents & Standards:
MIL-STD-704F
