Main Technical Parameters:
1. It has standard six-phase current and six-phase voltage simultaneous output, current 30A/phase, voltage 125V/phase. Six-phase current in parallel can reach 180A. It can test various traditional relays and protection devices, and also conduct various tests on modern microcomputer protections, especially for transformer differential protection and standby power supply automatic switching devices, making testing more convenient and accurate.
2. Equipped with an independent dedicated DC auxiliary voltage source output, with output voltages of 110V (1A) and 220V (0.6A) respectively, to provide DC working power for relays or protection devices that need it. It has software self-calibration function, avoiding the need to open the chassis to adjust potentiometers for calibration accuracy, thus greatly improving the stability of accuracy.
