Product Overview
The TM Series Ultra-low Voltage Automatic AC Voltage Regulator is designed to maintain stable output voltage even under severely fluctuating grid conditions. Using a digital control circuit and electromagnetic relay tap-switching, it automatically adjusts voltage to ensure consistent 220V output, even when input voltage drops as low as 95V.
Main Features
- Ultra Low-voltage Input: Can regulate power even when grid voltage drops to 95V, maintaining steady 220V output
- Wide Input Range: Supports input voltage from 95V to 270V depending on model
- Digital Control: Uses digital integrated circuit sampling control system for precise regulation
- Automatic Protection: Cuts off output when voltage exceeds or drops beyond safe range, protecting connected appliances
- Overload Protection: Automatic overload detection and protection
- Surge Resistance: Strong surge protection ensures reliability and long service life
- Flexible Mounting: Desk type for smaller models, wall-mounted or desk type for larger models

Technical and Application Notes
The TM stabilizer uses a sampling control system composed of digital integrated circuits to control electromagnetic relays and change the tap of the auto-transformer. This design achieves stable output voltage even with ultra-low input conditions. The product is especially suitable for areas with unstable or low-voltage grid supply.
Important Selection Notes: When using with appliances that have high start-up currents (such as air conditioners, freezers, refrigerators), the stabilizer capacity should be at least 3 times the rated power of the appliance to ensure proper operation.
Typical Applications
- Refrigerators and freezers
- Air conditioners
- Televisions and computers
- Electric fans and lighting systems
- Medical instruments
- Office equipment
- Communication equipment
- Areas with unstable or low grid voltage
Ordering Support
When ordering TM series voltage regulators, please specify:
- Required capacity (kVA)
- Input voltage conditions in your area
- Types of appliances to be connected
- Preferred mounting type
Ensure sufficient capacity margin for appliances with high start-up currents.
