功能描述

Constant current output feedback synthesis of use (hereinafter referred to as the constant current DDDL-H current of generator is an up flow reactor), is my company uses Germany the new module, and my company's existing technology in 2004 in the second half of their own research and development of test equipment, uses the numerical control technology, anti-interference ability is strong, and a generation of up flow is compared, with low power consumption, high capacity of self coupling voltage regulating device, and the hardware of the IGBT tube and high permeability core produced by the converter, through SPWM, inverter, PID control, measurement and software compensation and other new technology, product, power, small volume, weight light, good waveform, output stability, response speed, etc.. Mainly used for thermal relay, motor protector, contactors, breaker device, high voltage fuse, air switch, switch cabinet, circuit breaker, protection screen calibration, for a busbar protection and a variety of current transformer ratio test project, suitable temperature Shengheng flow experiment, is widely used in electric power, railway, petrochemical, metallurgy, mine and so on enterprise of scientific research, production and electrical field test.
