Overview
HVLP series Linear High Voltage Power Supplies are High-voltage DC power supplies that achieve AC/DC conversion through power frequency transformers and transistor loop control. Compared with switching high voltage power supplies, linear high-voltage power supplies have higher stability, higher accuracy, and lower output ripple. And the most important, because of the use of the power frequency AC/DC conversion principle, the linear power supply has no high-frequency radiation interference, and it is especially suitable for use in places with restrictions on EMC and EMI.
The HVLP series linear power supplies have a wide range of output specifications, the output power ranges from 1KW to 400KW, and the output voltage can reach up to 50KVDC, and accept customization.
The whole series linear power supply adopts industrial-grade metal chassis, pure copper AC/DC multi-insulation high-voltage transformer with varnish treatment, high-reliability multi-transistor filter loop, ensuring the power supplies can run for a long time at full load with high stability, high accuracy, and ultra-low ripple electronic characteristics, equipped with a complete protection circuit, which can better ensure the reliability of the linear power supply itself and the safety of the customer's load.
The output voltage and current can be adjusted by the 10-turn potentiometer with scale and lock on the front, equipped with 4 1/2-digit high-resolution LED meters for output value reading, and RS communication interface can also be added for remote control and monitoring of linear power supplies.
