I. Product Overview
DC hipot tester adopts high frequency pulse width modulation (PWM) technology to make closed adjustment with high voltage stability, small ripple factor and fast reliable protection circuit. The wide temperature LCD screen adopts green back light, which enables clear display either in bright light or in darkness. High-pressure components use Dupont new filling material, making the product more stable and reliable. Products are widely used in electricity power supply departments, power transmission and transformation engineering company and preventive test of large industrial enterprises and scientific research institutes as regulated dc high voltage power supply.
II. Main Functional Characteristics
1、DC hipot tester adopts high frequency PWM technology to make closed adjustment with high voltage stability, small ripple factor and fast reliable protection circuit. The generator can endure direct discharge by devices of large capacitance. It is of small size and of light weight, convenient for field use.
2、Full range of linear smoothly adjusted voltage, with voltage regulation accuracy smaller than 0.1%; voltage measurement accuracy is 0.5%, resolution 0.1kv; Current measurement accuracy is 0.5%, the minimum resolution: control box 1µA, shock resistance current 0.1µA.
3、The generator uses AC 220 V power supply (AC220V±10%, 50 hz±1%), the ripple factor is less than 0.5%, and can be used for all-weather at the site .
4、High voltage multiplier uses Dupont materials for full solid encapsulation, overcoming the inconvenience brought by the air and oil filled equipment. Broad base and outer cylinder of light quality makes it stand steadily and more convenient for maintenance.
5、75% MOA voltage switch button, simple and convenient testing arrester.
6、Over-voltage setting function displays the over-voltage value during regulation process; perfect protection against discharge of over-voltage, over-current and short circuit. This is the best companion for cable experiments.
7、Perfect break line and non-zero potential start protection function protects the operator and samples at any time. This product has overall design of shock-proof control box, concise, clear panel design and voice prompt for operation.
