Leach Introduces Three New Series of Next-Generation SSPCs

BUENA PARK, Calif., July 17, 2006 - Continuing its commitment to develop the most advanced Solid-state Power Controllers (SSPCs) on the market, Esterline Corporation component and equipment manufacturer Leach International has released three new models of multi-channel, next-generation programmable SSPCs for use in compact, microprocessor-controlled Secondary Power Distribution Units (SPDUs).

Designed for operation in 28Vdc systems, the EPM-109, -110 and -111 Series SSPCs all provide the latest micro-controller and Power FET technology incorporated into a Printed Circuit Board (PCB). They feature non-derated switching for all types of load while protecting against overload and short circuit. In addition, each includes an extensive Built-in-Test (BIT) feature that verifies all critical functions at startup and then continuously throughout operation.

These fast-acting, high-reliability units also include a serial data bus interface, programmable ratings and trip parameters, low voltage drop and power dissipation, and high voltage isolation.

The EPM-109 Series is a five-channel SSPC with three channels programmable up to 7.5 Amps at 85°C and two channels programmable up to 12 Amps at 85°C, while the EPM-110 Series provides two channels programmable up to 40 Amps at 85°C. Both models have no derating for lamp, motor and inductive loads. The EMP-111 Series offers two channels programmable up to 60 Amps at 85°C.

Examples of these new SSPCs will be featured at the Esterline exhibit, Hall 1, Stand B11, Farnborough Air Show, July 17-23.

Leach International Corporation, a leader since 1919 in high-reliability power switching components, is a subsidiary of Esterline Technologies and one of the largest manufacturers of electrical switching and control devices for the aerospace industry. .
