The 120V intelligent power distribution box is a secondary power distribution device for the 120V DC power system. It is used for the power distribution management of electrical equipment. It has the short-circuit and over-current protection for the load, and can regularly report the BIT information of the SSPC module through the RS422 bus and display product performance and working status.
The relay’s overcurrent protection software algorithm is based on the fusing principle of fuses. It provides up to 8 protection curves according to the needs of different loads, thus meet the requirements of different characteristics of inductive, resistive, capacitive and lamp load. It is suitable for the field of defense, and can be used in the control system of tanks, aircraft, ships and ground equipment.
1PWA is a single-channel high-power SSPC series solid-state power controller with a load voltage of 28Vd.c.~270Vd.c., and a load current of 10A~100A.
Controller featured functions:
It is suitable for the field of defense, and can be used in the control system of tanks, aircraft, ships and ground equipment.
The 2JB2-910 relay is an ultra-miniature, hermetically sealed, armature relay for commercial and space navigation applications. Its low-profile height makes it an ideal choice where extreme packaging density and/or close PC board spacing are required. Unique construction features and manufacturing techniques provide overall high reliability and excellent resistance to environmental extremes.
4WAZMK-1 is a serialized SSPC module product, which integrates 4 channels of 35A solid-state power output, and has 4 independent channels of emergency control. Various overcurrent protection and short circuit protection thresholds can be set within the range of its specification through software, which make it meet the power distribution needs of different working current devices in the intelligent power distribution system.
Actuator control and feedback components have overcurrent protection, status feedback functions and external switch status detection and are used for power distribution management of multiple loads. Its main functions are to receive the host computer control command through the CAN bus to control the load on and off, and obtaining the load current; It detects the working status of the external 40 switches through the optocoupler isolation and reports the load and working status to the control center through CAN bus.
The redundant input box of the actuator is mainly used for detecting the internal state of the system, receiving commands and reporting inputted state information through the CAN bus. There are dual redundant detection modules inside the input box, with a total of 128 detection circuits.
The information processor has the function of managing the information of the airborne equipment. It completes the collection of other sub-equipment references within the electrical system and uploads them to the flight controller, data recorder and ground testing equipment through the RS422 bus. The processor has the functions of analog signal acquisition, temperature detection and DIDO interface.
