⚙️ Product Description
Fundamental:
The voltage regulator is a continuously adjustable autotransformer with a turns ratio. When the voltage regulator brush slides along the polished surface of the coil by means of the hand wheel main shaft and the brush holder, the turns ratio can be continuously changed. Thereby the output voltage is smoothly adjusted from zero to the previous high.
Adaptation:
TDGC3 series regulators are characterized by non-distortion waveform, small size, light weight, high efficiency, convenient use, reliable performance and long-term operation. They are used for voltage regulation, temperature control, dimming, power control, etc. Ideal for metallurgical instrumentation, electromechanical manufacturing, light industry, scientific experiments, utilities, and household appliances.
Operating Conditions:
- Ambient temperature: Max +40°C, Min -15°C
- Altitude: Not exceeding 1000 meters
- Relative air humidity: Monthly average 90% (at 25°C)
- Power supply waveform: Sine wave or similar
- Environment: Free from corrosive gases, chemical deposits, or explosive media
- Vibration: Free from severe vibrations and bumps
- Usage: Indoor use only
Note! Choice Tip: This regulator product cannot be used in parallel.
