Voltage Protector
PN2-VAFDM Voltage Protector
TPKELE PN2-VAFDM is a 5-in-1 self-resetting voltage protector with a multi-function meter displaying voltage, current, power (W), frequency (Hz) and accumulated energy (kWh). With over-current counting, preset power level and fast power-off protection, it suits home energy monitoring, light-commercial power-quality analysis and solar PV installations.
Key Features
- 5-in-1 — voltage, current, power, frequency, kWh
- Self-resetting over / under voltage & over-current protection
- Over-current counting + preset power level
- Fast power-off protection
- 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.
