Developed by our company developed test equipment is the DDDL-1000Q high current generator, which combines the advantages of similar products at home and abroad in a body, and adopts the technology of numerical control, anti-interference ability strong, and a generation rise flow is compared, because of the low power consumption and large capacity self coupling voltage converter and high permeability core, with the advantages of high output power, small volume, light weight, etc., fully automatic high current generator with current settings, according to set program automatically lifting, with feedback, according to the working time, temperature test, test ratio and other functions. The current measurement circuit includes a micro current zero impedance CT, a program controlled amplification circuit and a sampling circuit.

The voltage measuring circuit comprises a PT isolation signal collecting circuit, a programmable amplifying circuit and a sampling circuit. By the 16 bit microcontroller using computer digital real-time collecting method, by measuring the voltage signal amplitude, according to the ratio between the voltage, can calculate the pressure in the test voltage value, through measuring the voltage signal amplitude with the set voltage value are realized and compared the function of automatic timing, according to current proportional relationship, can calculate the current size of the output device by measuring the current / voltage signal amplitude with the set value are realized and compared over current protection function.
