Frequency Converter
ESA-NA series0
ESA-NAシリーズ0
Specifications PWM control allows for a small, lightweight, and low-cost 50Hz <--> 60Hz frequency converter with variable output voltage.
Characteristics Variable frequency is possible. (Standard is 50/60Hz switchable)
Voltage is variable. (0 - 130V)
High-precision reference sine wave and output voltage are compared and controlled at high speed, outputting a low-distortion voltage waveform without being affected by distortion of the power supply waveform or nonlinear loads.
Momentary power outages (approx. 30mS) are also compensated for.
Rack mount compatible for easy integration.
ETC Power supply for motor testing
Power supply for testing home appliances, etc.
Power supply for automatic packaging machines, etc.
Other Outputs a low-distortion sine wave.
This frequency converter uses PWM control to achieve a small size, light weight, and low cost.
