E Series

The high voltage source measuring unit has the characteristics of high output and measuring voltage (3500V), and can output and measuring weak current signal (1nA). The instrument works in the first quadrant, output and measurement voltage 0~3500V,can be expanded to 10kV, output and measurement current 0~100mA. Supports constant-voltage and constant-current working mode and diversified I-V scanning modes. The HV high voltage meter can be used in IGBT breakdown voltage test, IGBT dynamic test busbar capacitor charging power supply, IGBT aging power supply, lightning-proof diode voltage test, varistor voltage test and other occasions. The constant current mode is of great significance for rapid measurement of breakdown point.
