TECHNICAL DATA

DATASHEET 5065, A

DC Solid State Power Controller Module

Description:

This product is a Solid State Power Controller (SSPC) Modules; the electronic equivalent to electromechanical

circuit breakers with isolated control and status. It is designed to operate with minimal heatsink requirements.

It is a microcontroller-based Solid State Relays rated up to 50A 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.

This product is programmable with a simple jumper configuration connector in steps as 30A / 40A / 50A.

The product series also allows programming the Instant Trip level at three different levels: 150A, 200A and

250A.The Battle Override that allows the protection to be turned off is a standard option.

Compliant Documents & Standards:

MIL-STD-704F

MIL-STD-217F, Notice 2

Aircraft Electrical Power Characteristics, 12 March 2004
