The ZBK intelligent pump controller combines upper- and lower-water-level sensing with automatic and manual control. The captured models cover single-phase 220V and three-phase 380V pump motors from 0.37kW to 15kW.
Control and protection
Automatic or manual operating mode with upper- and lower-level inputs.
Phase-loss, overload, no-load, overvoltage and undervoltage protection.
Adjustable no-load restart time from 1-999 minutes, fault memory and anti-rust cycling.
AC digital probe detection for upper-pool, lower-pool and constant-pressure connection arrangements.
Selection and installation
Choose the controller by motor power and supply voltage, then use the applicable connection diagram for the water source, storage tank and pressure-switch arrangement.
