AC DC Elevators Single Phase Home Voltage Protector Automatic With Power - On Delay

AC DC Elevators Single Phase Home Voltage Protector Automatic With Power - On Delay

High-precision : The use of powerful microprocessors, especially AC sampling technology, voltage measurement accuracy of ± 0.5%, can display three-phase power line voltage value, the equivalent of three-phase voltage meter function.

Full-featured : Three-phase voltage display, over-voltage protection, under-voltage protection, phase loss protection (phase protection), three-phase voltage imbalance protection, phase sequence protection (wrong phase protection), sound and light alarm in one.

High reliability : The unique three-phase power supply technology ensures that the protection, alarm, and display functions work properly even at extremely low voltages and even in the absence of phase.

Humanization: All protection functions can be selected ON or OFF, and action thresholds and operation time can be set to facilitate the user to adjust flexibly according to actual needs. You can also view and modify settings parameters during normal operation.

Intuitive display : The use of special large, wide temperature, high-definition Chinese LCD display, the normal operation shows the voltage value of the three-phase power line; fault directly in Chinese to display the cause of the failure, and can display which phase failure, and failure at the same time The voltage value makes it easy to quickly determine the cause and location of the fault.

Fault indication : When a fault condition is detected but the trip time has not been reached, the fault indicator is on and the backlight blinks. After the trip action, the fault indicator flashes, the backlight is on, and the buzzer sounds intermittently.

Fault record : Non-volatile memory technology is used. When an overvoltage, undervoltage, phase loss, imbalance, or reverse phase sequence fault occurs, the fault is recorded. Even if the product is completely powered off, the fault information can be memorized to facilitate troubleshooting. Analyze the cause of the fault after accidents to facilitate troubleshooting.
