Detailed Description

Description : S521 intelligent pump controller single phase 220v ,it has the function of dry run protection with sensor free ,it can memorize the wroking ampere when the pump motor under normal state ,if the controller detected that the real running ampere value lower than the calibrated working ampere which will order pump stop running automatically . Electrical connection to the power supply line and electrical pump : Application : # Control and protect universal pump # Using water level sensor or float switch to control pump start and stop # Applied for water supply by liquid level control through float switch or liquid probe # Applied for water supply by pressure control through pressure switch and pressure tank # Applied for drainage by liquid level control through float switch or liquid probe Typical usage scenarios include: -Houses -Flats -Holidays houses -Farms -Water supply from wells -Irrigations of greenhouses, gardens, agriculture -Rain water reuse -Industrial plants -Waste water tank / Sewage sink Feature advantage : # Enough space for installing one capacitor inside # Push button calibration # Memory function when power off & recovery # Over load protection # Pump stalled protection # Dry run protection with sensor free # Under voltage protection # Over voltage protection Main installation data : Working temperature: -25-- +55 Working humidity: 20%--90%RH, no drips concreted Degree of protection: IP22 Install position: Wall mounting Unit dimension (L x W x H): 170 x 155 x 85 mm Technic parameter : - - - - Control characteristic | Double liquid level control | Pressure control | Control method | Auto / Manual | Liquid level control charactersitic | Liquid probe / float switch | Pressure control characteristic | Pressure switch / pressure tank | Trip response time of overload | 5sec-5min | Trip response tiime of dry run | 6 sec | Recovery time of over load | 30 min | Recovery time of under / over voltage | 5 min | Recovery time of dry run | 30 min | Trip voltage of over voltage | 253V | Trip voltage of under voltage | 175V | - - - -
