Description:

The Solid State Power Controller (SSPC) Module is a microcontroller-based Solid State Relay rated upto 25A designed to be used in Army, Air force and Navy in 28V DC applications. This module has integrated current sensing with no derating over the full operating temperature range. The module is the electronic equivalent to an electromechanical circuit breaker with isolated control and status.

Module Features:

• Epoxy Shell Construction

• Solid State Reliability; Low Weight (20 gms) - High Power Density

• Same Pin Out as Industry Standard SSPCs in a Smaller Outline

• Extremely Low Power, No Derating Over the Full Temperature Range

Electrical Features (SPDXXD28 Series):

• 28VDC Input with Very Low Voltage Drop; 60mV, typ. @15A

• True I2t Protection from 32A to 250A with Nuisance Trip Suppression

• Instant Trip Protection (50 µsec typ) for Loads Above 250A

• Unlimited Interrupt Capability; Repetitive Fault Handling Capability

• Thermal Memory

• Internally Generated Isolated Supply to Drive the Switch

• Low Bias Supply Current: 20 mA typ @ 5V DC

• High Control Circuit Isolation: 750V DC Control to Power Circuit

• Soft Turn-On to Reduce EMC Issues

• EMI Tolerant

• Module Reset with a Low Level Signal; Reset Circuit is Trip-Free

• TTL/CMOS Compatible, Optically Isolated, Input and Outputs

• Schmitt-Trigger Control Input for Noise Immunity
