RSFシリーズ0
Specifications Ricoh Slide Transformer is a general term for sliding voltage regulators. Ricoh Slide Transformer has a long track record as an ideal AC voltage regulator that does not generate waveform distortion.
Characteristics ・No distortion of generated waveform
The output can be extracted with almost no distortion for the input sine wave.
・Stepless output control
The output voltage can be continuously adjusted steplessly, so you can obtain the output voltage you need.
・Compact and lightweight
By adopting Class B insulation, we have succeeded in making it compact and lightweight (some are Class A)
・High efficiency
Even under the worst conditions, it is extremely efficient at about 90%, making it an energy-saving type.
ETC ・Precise adjustment of power supplies for testing and inspection
・Precise adjustment of rotation speed
・Adjustment of excess and insufficient voltage in industrial, scientific and chemical equipment, and household electrical appliances
・Precise adjustment as a lamp lighting power supply
