An Electronic Circuit Breaker Unit/Power Distribution Unit has power inputs from different sources and power outputs to feed the loads. The 28VDC Electronic Circuit Breaker Unit/Power Distribution Unit has voltage and current measurement units. It can also perform detailed tasks such as soft start, over-current protection, short circuit protection, sequential opening and energizing the desired loads for power saving according to working scenarios.
Each Electronic Circuit Breaker Unit/Power Distribution Unit is designed with fail-safe logic that provides a configuration that allows the utilization of input power to the appropriate loads, ensuring that power is retained on essential loads. It has a redundant design that allows the Electronic Circuit Breaker Unit/Power Distribution Unit to prevent single-point failures. Electronic Circuit Breaker Unit/Power Distribution Unit also utilizes WoW (Weight on Wheel) logic, extensive Built-In-Test capabilities and I2T logic.
