3500V/100mA High Voltage Power Source E300 High Voltage Source Meter
The high voltage power source E300 can output and measure voltages up to 3500V (expandable to even higher levels). It also has the ability to measure weak current signals as low as 1nA, with a current output range covering 0 - 100mA. The E300 not only supports constant - voltage and constant current operating modes but also provides a comprehensive set of I-V scanning modes, making it suitable for high-end testing requirements such as IGBT breakdown voltage testing and IGBT aging power supplies. Its high precision measurement capability in the constant current mode enables the E300 to perform outstandingly in quickly locating breakdown points.
Product Features
▪ Ultra-short Voltage Build-up and Efficient Heat Dissipation: With a high voltage build - up time of 5ms, it greatly reduces the heating of the device under test during power - on, improving testing efficiency.
▪ High-power Output and High-precision Testing: The maximum output per unit is 3500V, the maximum current is 100mA, and the maximum power is 350W, which can be extended to 10kV. Combined with an accuracy of 0.1%, it can complete leakage current tests at the nA level under high voltage.
▪ Rich Output Modes and Powerful Scanning Functions: It supports constant - voltage or constant - current output, synchronously tests voltage and current, and supports linear, logarithmic, and user - defined scanning to meet various testing scenarios.
▪ Current-limiting Protection, Stable and Reliable: It has constant-voltage and current-limiting functions, effectively avoiding tube explosion and ensuring the safe and stable operation of the equipment.

Applications
▪ IGBT Breakdown Voltage Test: It is used to evaluate the insulation performance and reliability of the Insulated Gate Bipolar Transistor (IGBT) when it withstands the maximum reverse voltage.
▪ IGBT Aging Power Supply: This is to test the durability and long - term operational stability of IGBT devices through long - term load tests.
▪ Lightning - protection Diode Voltage Withstand Test: It detects the breakdown protection performance of the lightning - protection diode under extreme voltage conditions such as lightning surges.
▪ Varistor Voltage Withstand Test: This verifies the non - linear resistance characteristics and voltage clamping ability of the varistor in over - voltage scenarios.
