BA5X series AC constant current source series products

Product features: (1) The current closed-loop control strategy is adopted to achieve stable current output, which is not affected by load changes. Compared with the traditional test method of voltage source + load + equipment to be tested, the capacity is reduced, the energy consumption is reduced, and the large-capacity load is saved. (2) The use of SPWM high-frequency inverter to achieve constant current output, compared with the motor control type constant current source, constant current accuracy is high, response speed is fast, distortion degree is small, high efficiency, due to external
