DATASHEET 5186, Rev -
Programmable 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 30A designed to be used in high
reliability 28V 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 6 SSPC families, with each family being
programmable over a 5:1 current range.
SPDP05D28-1: Programmable from 1A to 5A
SPDP10D28-1: Programmable from 2A to 10A
SPDP15D28-1: Programmable from 3A to 15A
SPDP20D28-1: Programmable from 4A to 20A
SPDP25D28-1: Programmable from 5A to 25A
SPDP30D28-1: Programmable from 6A to 30A
