Power Distribution Units offer advanced circuit protection.
September 6, 2006 -
Microprocessor-controlled Secondary Power Distribution Units (SPDUs) utilize programmable, multi-channel Solid-state Power Controllers (SSPCs) with dual redundant power supplies and dual redundant data bus. Featuring continuous built-in-testing, 6.75 lb products distribute 28 Vdc power to aircraft loads and provide protection for wiring. They can receive input power from multiple sources and control loads based on commands received through data bus or by discrete signals.

Leach SPDU Series Provides Advanced Circuit Protection Using Next-Generation SSPC Technology
BUENA PARK, Calif., July 17, 2006 - A microprocessor-controlled Secondary Power Distribution Unit (SPDU), featuring multi-channel, next-generation Solid-state Power Controllers, has been released by an Esterline Corporation component and equipment manufacturer Leach International.
Designed to distribute 28Vdc power to aircraft loads and provide protection for the wiring, Leach SPDUs can receive input power from multiple sources and control loads based on commands received through the data bus or by discrete signals.
The SPDU Series features multiple programmable SSPCs (shown are 6 channels rated up to 10 Amps at 85°C and 22 channels rated up to 5 Amps at 85°C) with standard dual redundant power supplies and a standard dual redundant data bus. Control options include data bus, discrete signal or manual push buttons, and the extensive built-in testing (BIT) takes place at startup, runs continuously and also can be initiated when desired.
These lightweight units (approximately 6.75 lbs.) benefit from the many features of Leach SSPCs, which include low voltage drop and power dissipation, backup wire protection, and optional arc fault protection. Plus, by eliminating connectors, junction boxes, wires, circuit breakers and other components, Leach SSPCs dramatically reduce wire volume while improving accuracy, repeatability and arc fault protection.
Featuring a flexible architecture to meet a variety of requirements, Leach SPDUs can accommodate different power inputs and numbers/ratings of SSPCs. In addition, a variety of data bus types is available, including MIL-STD-1553B, ARINC 429, ARINC 485, RS-232 and CAN Bus.
The new SPDU Series will be featured at the Esterline exhibit, Hall 1, Stand B11, Farnborough Air Show, July 17-23.
