Tomzn Adjustable Voltage & Current Protector
The Tomzn Adjustable Voltage & Current Protector offers smart, real-time protection from overvoltage, undervoltage, and overcurrent for home and industrial use.
The Tomzn Adjustable Voltage & Current Protector is a smart electronic protection device designed to safeguard electrical equipment from voltage fluctuations, overcurrent, and short-circuit conditions. Built for reliability and precision, it automatically disconnects the power supply when voltage or current exceeds preset limits, preventing damage to connected appliances or systems.
Featuring adjustable upper and lower voltage thresholds and customizable current limits, the Tomzn protector ensures stable and safe operation of sensitive devices. The digital display provides real-time voltage, current, and status information, while the automatic reset function restores power once parameters return to normal.
This device is ideal for homes, offices, and industrial applications, offering comprehensive power protection for air conditioners, refrigerators, pumps, motors, and other valuable equipment.
Key Features:
-
Adjustable voltage and current limits for customized protection
-
Automatic power cutoff and reset during abnormal conditions
-
Real-time digital display of voltage and current values
-
LED indicators for operational status and fault alerts
-
Compact DIN-rail mount design for easy installation
-
Supports single-phase AC systems (typically 220V)
-
Protects against overvoltage, undervoltage, and overcurrent
