SPDPXXD28 SERIES

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:

Programmable from 1A to 5A

SPDP10D28:

Programmable from 2A to 10A

SPDP15D28:

Programmable from 3A to 15A

SPDP20D28:

Programmable from 4A to 20A

SPDP25D28:

Programmable from 5A to 25A

SPDP30D28:

Programmable from 6A to 30A
