Product Overview
The protector continuously monitors line voltage and current in single-phase power systems. When abnormal conditions occur, such as sudden power grid failures or overcurrent events, the device instantly disconnects the load to prevent damage to sensitive electrical equipment.
Functioning as a highly precise single phase voltage monitoring relay, it offers fully adjustable protection parameters—including adjustable voltage, current tripping, and automatic reclosing time—allowing it to be configured to match real-world operating conditions.
It is highly recommended as a primary voltage protector for home distribution boards. Whether you need a dependable over voltage protector for home appliances or a robust commercial safeguard, this unit acts as both an efficient overvoltage protection device during sudden grid spikes (handling up to 300V) and a strict undervoltage protection device during brownouts, complete with a dual voltage/current display for real-time monitoring.
Single Phase Voltage Protector Features & Benefits
- Overvoltage & Undervoltage Protection: Automatically disconnects the load to prevent equipment damage when voltage exceeds or falls below safe limits.
- Adjustable Voltage Parameters: Customizable thresholds (Overvoltage 130-300V, undervoltage 80-210V) tailored for different grid applications.
- Automatic Recovery: Automatically reconnects power when voltage returns to the normal range, with an additional manual recovery option.
- Real-Time Voltage Monitoring: Continuous detection of AC voltage and current fluctuations via a clear, multi-mode digital display (showing voltage, current, frequency, and active power).
- Compact Design: DIN-rail compatible for easy and quick integration into standard distribution panels.
- Setup Lock Feature: Built-in security lock to prevent protection parameters from being modified by mistake.
- Advanced Stability: Features an embedded RTOS (Real-Time Operating System) to improve system performance, stability, and maintainability.
- Energy-Saving Mode: Intelligently reduces the brightness of the digital display when the device is not actively being configured.
