SPDPXXD28 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 40A 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 4 SSPC families, with each family being programmable over a 2:1 current range:
SPDP05D28: Programmable from 2.5A to 5A
SPDP12D28: Programmable from 6A to 12A
SPDP25D28: Programmable from 12.5A to 25A
SPDP40D28: Programmable from 20A to 40A
