1 / 8Over Voltage Protector
PN2-VAFD 5-in-1 Self-Resetting Voltage Protector with Voltage, Current, Power, Frequency & kWh Meter
The Soltree PN2-VAFD is the most advanced model in the PN2 series — a true 5-in-1 device that combines full over/under voltage and over-current protection with a multi-function power meter in a single DIN rail unit. Where the PN2-VAK displays voltage, current, and kWh, the PN2-VAFD adds real-time power (W) and supply frequency (Hz) to the display, giving installers and end users a complete picture of circuit performance without any additional metering hardware.
This makes it ideal for light commercial premises, rental properties with sub-metering requirements, home energy monitoring setups, and any installation where a detailed understanding of power quality and consumption is needed alongside automatic fault protection. The multi-color display presents all five metrics simultaneously: voltage, current, active power in watts, supply frequency in hertz, and cumulative energy in kWh. Additional smart features include over-current counting, preset power level alerts, and fast power-off protection.
Protection parameters are fully configurable — over-voltage (240–300V AC), under-voltage (140–230V AC), over-current (1A to rated maximum) — with password lock and adjustable reset delay (0–999s, default 60s). Available in 40A, 63A, and 80A variants; AC 110V customizable for export markets.
