TOMZN Adjustable Over Voltage Relay Current Limit Under Current Protector V-I-kW-kWh Display AC110V 230V 63A Water Level Control

DDS238-VAP 2P 85-300VAC  63A Over voltage protection、Over current protection、Under current protection(without under voltage protection).General description  DDS238-VAP-W type water pump Protective Device is designed to measure single phase two wire AC active energy and control water pump automatic working. This device have over voltage protection function and it can cut off the water pump when the water tower is full or no water in the pipe. So it can help people to reduce water waste and avoid the water pump motor over-temperature destroyed for long time working.Product features1. LCD display with backlight , can display total active energy (kWh) , real time current (A) , voltage(V) ,  active power (W) .2. Product self-design has function of lighting protection3. Overvoltage protection and delay power on protection 4. Control water pump automatic working. We can set a lower limit and upper limit to check whether should make the water pump on or off . because the water pump work current will drop when no water in the pipe and the water pump work current will rise when the water tower is full . We can select auto-Reclosing mode or manual--Reclosing mode to drive the water pump work .5. it also can set water pump recycle working time6. Led indication of overvoltage protection, upper limit current protection ,lower limit current protection , power7. switch off the load when power offProduct parametersInput working voltage85~300VOvervoltage protection value85-300V ( default 270V)Current limit1-63A ( default 40A)Rated frequency50/60HzDelay in switch on after power off2-255V ( default 2s)Voltage circuit power consumption≤1WCurrent circuit power consumption<1VAActive energy display range0~9999.9kWhVoltage/current/active power accurate0.50%Active energy accurate+1% (IEC62053-21)Operating temperature-25℃~+70℃Storage temperature-40℃~+80℃Relative humidity≤85%Altitude≤2500mElectromagnetic EnvironmentE2Mechanical life≥100000 cycles
