Three phase precision purification stabilized power supply

summary:

The JJW/JSW series precision purification and voltage regulation power supply adopts the internationally advanced sine energy distribution program power regulation technology, which is a new development level of AC voltage regulation technology. Its circuit consists of a sine energy divider and a high-power filter connected in parallel. It has the advantages of high voltage regulation accuracy, high overload capacity, good reliability, strong anti-interference ability, high efficiency, long-term continuous operation, long service life, and is suitable for various types of loads (resistive, inductive, capacitive). It is an ideal replacement product for 614 series electronic voltage regulators and magnetic saturation voltage regulators.
