1 / 8Over Voltage Protector
PN2-VAK Self-Resetting Voltage Protector with kWh Energy Meter 40A–80A
The Soltree PN2-VAK is the most feature-complete model in the PN2 series, combining over/under voltage protection, over-current control, and real-time kWh energy metering into a single compact DIN rail device. While the PN2-VA2 through VA5 models focus purely on protection and automatic restoration, the PN2-VAK adds a built-in kWh meter that tracks cumulative electricity consumption — making it suitable for sub-metering in rental properties, individual tenant circuits, light commercial premises, and any installation where both protection and consumption monitoring are required in one unit.
The tri-color digital display provides simultaneous visibility of three metrics: real-time voltage in red, current in green, and total kWh in blue. Current is not displayed below 1A; kWh is not displayed below 0.01 kWh, keeping the display clean during standby.
Protection parameters are fully configurable: over-voltage from 240V to 300V AC, under-voltage from 140V to 230V AC, and over-current from 1A up to the rated maximum. A 0.5-second disconnect activates on fault, with automatic power restoration after the adjustable reset delay (0–999 seconds, default 60s). Password lock prevents unauthorized changes. Available in 40A, 63A, and 80A variants; AC 110V customizable for export markets.
