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.
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.
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.
Bus bar A, bus bar B and bus bar C are arranged inside the central power distribution device. With the functions of on-off control, overload protection, switch status feedback, current monitoring, power monitoring, external temperature sensor signal collection, bus bar switching, RS422 bus interface.
The solid-state power controller is mainly used to realize the function of distribution control, overload protection of the on-board controllable power supply and related electrical parameters detection. The module contains six controllable power supplies. It communicates with the power supply system controller through the CAN bus and reserves one RS422 communication function. The module can be switched through jumpers between A/B modes with different output current,
The TZ220AC-50 AC intelligent power distribution module complies with the “SJ20668-1998 General Specification for Microcircuit Modules”. With the intelligent functions such as automatic protection and detection, this series of products also have good resistance to high and low temperature, vibration and impact, and is of small size, light weight and high reliability. It can replace the conventional power distribution method of AC contactor/relay + fuse/circuit breaker, and is suitable for single-phase AC power distribution circuit of new generation weapon system.
TZ380AC-100AC intelligent power distribution module complies with the “SJ20668-1998 General Specification for Microcircuit Modules”.
