Purpose:
Suitable for DC Withstand voltage test and measuring leakage current of electric apparatus including the lightning arrestors, generators,transformers,switches and cables.
Character:
* High Voltage output includes 2 adjusting ways: general and fine;
* Using new IGBT devices and PWM techniques, low waveform coefficient.
* Built over-current, over-voltage and zero-start protection, effective
protection of personal and equipment safety;
* Small size, light weight, suitable for field use.
* Negative polarity output, zero start, continuous adjustable, having the function
of over voltage, over current, zero returning and ground protection. Operation
is safe due to strong function of auto protecting circuit, technical index of all
kinds surpassing industry standard and similar products.
* High stability in voltage regulation, smooth voltage regulation in full range. Voltage
regulation of output adopts import single multi-rings potentiometer with rough adjustment
and fine adjustment. Accuracy of voltage adjusting is better 0.1%, accuracy of voltage
and current measuring is less than 1.0%, and ripple factor is better than 0.5%.
* High accuracy and correct measuring. Voltage and current meter all have digital display,
with voltage resolution 0.1kV, and current 0.1uA. Voltage value applied to load test object
is displayed directly through voltmeter on control cabinet, which needn’t to be connected
with voltage divider on the outside when using, and lead connection is easy.
* Three concealed support legs are set at the bottom to increase the stability of
multivoltage tube.
