Datasheet
Overview
JK99500 series wide-range programming DC power supply has an ultra-wide working field. The combination of voltage and current settings can achieve a constant power supply of 2-3 times. One JK99500 can replace multiple traditional DC power supply of different specifications, reduce repetitive investment costs. This series has two working modes: constant voltage CV and constant current CC. It can be applied in automatic testing, process control, battery charging and aging testing, etc., of these occasions need high-quality DC stable power supply. This series of products has a zero voltage "soft switch" function, which can reduce the transient stress of the switch, thereby having a low output noise. Soft switch can also improve efficiency and reduce heat, so that the power supply has higher stability.
