HVLP Series High Voltage Linear DC Power Supply | |||||
|
|||||
Overview | |||||
HVLP series is high voltage linear DC power supply uses power frequency transformer AC/DC conversion technology, series voltage-rise circuit design and matured filtering circuit to ensure controllable and stable HV DC output. As it uses power frequency transformer, it is more reliable and durable than switching mode power supply that using high frequency PWM technology and it does not have high frequency radiation interference like switching mode power supply has. Its matured and perfect filtering circuit gives it super low ripple and very good output precision, also it has complete protection functions. As features above, this series is mostly used for HV capacitor charging, HIPOT test and other kinds of HV tests. |
