Bohemia, New York (September 2004) — DDC’s RPC (remote solid-state power controller) board technology offers substantially lower costs per channel than traditional RPC modules, sometimes called Solid State Power Controller (SSPC) modules. The lower cost per channel of the RPC Board Technology enables military ground vehicle, commercial aircraft, and military aircraft applications to benefit from this cost effective solution for power management systems that control power and protect wiring from overload conditions.
RPC boards realize a lower cost per channel by using modern control techniques, combining multiple channels on a single board, and utilizing surface mount technology. Each RPC board may contain up to 16 channels with a total current rating of 160 A per board. Manufacturing a single 16-channel board is more economical than manufacturing 16 single-channel modules.
The RPC board technology uses a DSP to provide on-board intelligence and flexibility. Each channel may be independently controlled, enabled, disabled, or reset. The current ratings of each channel may be individually set. Status outputs with current reporting are provided on the boards. The boards also have a Built-in-Test (BIT) feature. Communication protocol options include CANbus, RS-232, RS-422, and RS-485. Applications to date have been 28 V and this technology may be applied to higher voltages.
The RPC boards are designed to withstand rugged military environments such as humidity, vibration, EMI, and temperature. The boards are conformal coated to provide moisture resistance and are EMI tolerant. The mechanical design complies with standard ground vehicle and aircraft environmental requirements. The standard operating temperature range is —40 to +85oC, and boards may be up screened to —55 to +100oC.
“DDC’s RPC board technology provides a method of greatly reducing the price per channel for military and aircraft power management systems and simplifying power distribution system development while minimizing inventory requirements. This technology provides the greatest advantage where the channel count is high (8 to 16 channels per board), the current levels are at or below 25 A per channel,” said Jack Redus, Marketing Manager at DDC. “DDC has a standard 16-channel board that may be set to a customer’s specific requirements,” he added. Pricing is dependent upon number of channels, current ratings, and quantity. Contact the local DDC sales representative for additional information or a quote on a specific requirement.
