WS-NCV Series

item WS-NCV Series

AC switching power supply
WS-NCV Series0
WS-NCVシリーズ0
Specifications This is a stabilized power supply that adjusts voltage by directly switching AC power. Since the output voltage waveform is a sine wave, precise control is possible even in fields where control is difficult with phase control power regulators.
Characteristics Compact installation space
Stable output voltage precision
Sine wave output (sine distortion rate)
Load fluctuation feedback function
High efficiency (95% or more) and high power factor (0.98 or more)
Built-in noise filter for input and output
Equipped with three types of protection functions
Overcurrent limiter
Peak current limiter
Output cut-off when peak overcurrent is detected
A new type that is smaller and lower cost while maintaining the functions and performance of the old WSA and WSC series.
ETC For use as a control power source for various test equipment
For use as a countermeasure against voltage fluctuations on other lines due to load fluctuations
For use as a stabilized power source to counter power fluctuations
