Linear AC Constant Current Source

The constant current source is primarily used for calibration and testing of time-delay thermal trip tests conducted on various low-voltage electrical products within the low-voltage electrical equipment industry, such as circuit breakers, thermal relays, and motor starters. In the characteristic testing of low-voltage electrical products—particularly in applications where protective switches and electrical devices require rigorous testing of the thermal effects of specific currents, such as circuit breakers, fuses, thermal relays, and magnetic starters—the constant current source has found widespread application.
