High cost-performance DC stabilized power supply "YS Series"
DC Stabilized Power Supply "YS Series"
It is an economical DC stabilized power supply with no moving parts, making maintenance easy due to the thyristor control method.
The YS series is a constant voltage (CV) DC stabilized power supply with thyristor control. It has no moving parts, making maintenance easy, and it is highly reliable and economical. 【Features】 - Economical - Output voltage accuracy ±0.5% - Fast response 0.5 seconds (50-100% load) - Output voltage ripple 0.5% Vrms for three-phase input, 2% Vrms for single-phase input - Output voltage adjustable from 0 to 110% (accuracy not guaranteed below 25% of rated voltage) - Constant current function can also be added as an option - The rectification circuit replaces the rectifying elements with thyristors and controls the conduction angle of the thyristors, resulting in a fast response, no moving parts, easy maintenance, and long-lasting reliability.
