85-300V Backlight Adjustable Over And Under Voltage Protective Energy Meter - White 63A
- 1. LCD display with backlight , can display total active energy (kWh) , current (A) , voltage(V) , active power (W).
- 2. LCD display kWh (4 digital+1 decimal) , Bi-directional total active energy measurement ,reverse active energy measure in ttotal active energy.
- 3. Product self-design has function of lighting protection.
- 4. Overvoltage protection, under voltage protection and over-current protection can select auto-Reclosing pattern or manual--Reclosing pattern.
- 5. In case of over-voltage fault, under-voltage fault or over current fault in single phase line, tproduct can power off tline and can automatically restore connecting tline over a delay after voltage of tlien is recovered to normal condition.
- 6. In case of transient over voltage in line, tproduct can protect tequipment from false operation.
- 7. In case that tline subjects to unstable voltage or sudden power-off and power-on due to loosened connection and other fault, tproduct will disconnect tline.
- 8. When fault voltage of tline reaches tpeak, tproduct itself will not be damaged.
- 9. Under over-current protection pattern, you also can select Malignant load protection (Pure Resistive Load limit) which is used for Apartments and Stu Dormitories electric safety.
- 10. You can select tcircuit output cycle switch on/off pattern.
- 11. Led indication of overvoltage protection, under voltage protection and over-current protection.
- 12. Diversified design for tprotection, you can closed t any one of overvoltage protection, under voltage protection and over-current protection in any .
