ZD-110/ZD-220 Pump Controller   Thank you for interest of  the ZD-110 or ZD-220 High Pressure Pump System. Here is a brief introduction of this high pressure pump system, the Zide High Pressure Pump System consists of two major parts: Controller and Pump Unit. These two units connect to each other with signal and power lines. This Controller is custom made for this Pump Unit, so it will not be suitable to connect this Controller to a different Pump Unit other than the one that comes with this Controller.  Pump Controller  Pump Unit Outside Look  Pump Unit Internal Look  Pump Remote Controller         Introduction and Specification:  The Controller is designed to control the output pressure of the pump through a feedback from a pressure sensor and a built-in timer to control the On/Off time of the pump unit. The controller is expandable so as to control multiple Pump Units at once and the add-on Pump unit can be set to control an individual zone (ex: Zone 1). Thus, you have the freedom to start/stop all zones or manually start/stop a single zone from the front panel of the Controller Unit.   Down below is the electrical specifications and features of the Controller Unit:  Input Voltage: AC 110V or 220V (manually select through internal switch)  Input Frequency: 50 or 60Hz  Maximum Output Power: 200Watts  Maximum Pressure Setting: 70 Kg/cm²  Pressure Display Unit: Kg/cm^2, psi (pound square inch), BAR  Setting Range: 10 seconds ~ 60 minutes  Pressure Release Valve output: 0.1Amp  Water source control valve output: 0.1Amp For patent, certification and more detail info please check the Pump User Manual in our DOWNLOAD page.
