PN2-VA2 Self-Resetting Over/Under Voltage Protector 40A–80A
The Soltree PN2-VA2 is a self-resetting over/under voltage and over-current protector designed for homes, light commercial premises, and distribution boards where continuous protection without manual intervention is essential. When the supply voltage exceeds the user-set over-voltage or under-voltage threshold — or when current surpasses the over-current trip point — the PN2-VA2 disconnects the circuit within 0.5 seconds to prevent damage to appliances and sensitive electronics.
Once the supply returns to a stable, safe range, the device automatically restores power after an adjustable reset delay (0–999 seconds, default 60s), eliminating the need for a manual reset call-out. The high-resolution dual-screen digital display shows real-time voltage in red and current in green simultaneously, giving installers and users immediate circuit health information at a glance.
All trip thresholds are user-configurable via the front panel: over-voltage from 130V to 300V AC, under-voltage from 80V to 210V AC. A password lock function prevents unauthorized changes to these settings — important in shared or rental properties. Additional features include an energy-saving mode to reduce self-consumption and full support for OEM logo customization. Available in 40A, 63A, and 80A variants; rated supply voltage AC 220V (AC 110V customizable).
