Constant current output feedback synthesis of use (hereinafter referred to as the constant current DDDL-10000H 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 no longer with low power consumption and large 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, for breaker, 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.

SPWM hardware adjustment technology, fast response, stable output;

High power MOS/IGBT drive, reliable operation, strong overload ability;

Suitable for resistance, inductive, rectifier and other kinds of load;

With the voltage upper limit, lower voltage, overheating, and other abnormal conditions to protect the function;

Has the parameter memory function, the shortcut key operation way, uses the simple convenience;

The power frequency current can be adjusted online;

The bright LCD six bit array liquid crystal display, clear and eye-catching, large viewing angle, convenient production line;

With RS232 communication interface, the baud rate is 9600.
