Voltage Protector
STATS-03 Voltage Protector
TPKELE STATS-03 is a 3-input automatic transfer switch with over/under voltage and over-current protection. A triple digital display shows L1 / L2 / L3 input voltages, and priority switching (L1 → L2 → L3, customizable) keeps loads supplied from the first healthy source — ideal for CNC machinery, server rooms and solar-grid hybrid systems.
Key Features
- 3-way priority switching (L1 → L2 → L3, customizable)
- Triple display — L1 / L2 / L3 input voltage
- Over / under voltage + over-current protection
- Switching response time < 0.2s
- 35mm DIN-rail mounting

Frequently Asked Questions
When should I install a voltage protector?
Voltage protectors are recommended where mains supply is unstable or where sensitive appliances such as refrigerators, air conditioners and electronics need protection from voltage fluctuations and phase-loss events.
Does the voltage protector reset automatically?
Yes — after the mains voltage returns to a safe range, the protector reconnects the load automatically after a configurable delay (typically 5–600s).
Do you have three-phase models with phase-loss protection?
Yes, our three-phase voltage protectors detect over/under voltage on each phase, plus phase loss and phase sequence errors.
