    Basic Functional Features Operation Command Route 4 Routes: 1. Keypad control; 2. Digital input terminal control; 3. Communication control; 4. Water inlet pressure control
    Built-in Clock Built-in RTC for LCD keypad series
    PID Built-in PID Advanced PID calculation, convenient to realize close-loop control
    Host-auxiliary online system Can be extended to dual RS 485 communication; A driver can be set as the host in the system to control the work of other auxiliary drivers by communication (up to 5 auxiliary drivers). The host sends PID feedback to the auxiliary drivers and detects the state of them in real time. If there is an error, it will automatically skip this auxiliary driver, you can set a backup host. The host can communicate with the upper machine at the same time without being affected; The auxiliary drivers can also communicate with other devices at the same time.
    AVR Function Can automatically keep the output voltage stable when grid voltage fluctuates; This function is invalid when gird voltage decreases as factory setting.
    Stall Control Automatically limit output current and voltage during running, to prevent frequent overcurrent and overvoltage trips
    User Password Setting A 4-digit password can be set, which is a non-zero number; after setting, exit the password setting interface, it will take effect after 1 minute
    Parameter Lockup Function Define whether the parameters are locked under running or stop state to prevent misoperation
    Pump control functions Automatic Energy Saving Running Automatically lower output voltage at light load to achieve energy saving
    Automatically Startup when Powered on Optional: automatically startup when powered on, or startup delay
    Antifreeze Function Antifreeze operation selection, frequency, time, period
    Water Leak Detection Optimizing dormancy control by water leakage detection coefficient
    Water Supply Protection High Pressure Warning Detect the feedback pressure and protect the pipe network
    Low Pressure Warning Detect the feedback pressure and protect the pipe network & pump
    Dry Run Protection There are a variety of dry run protection detection methods (including sensorless methods). When the driver detects that the water pressure of the pipe network is lower than the dry run pressure, the system automatically stops working, and after a set time, it automatically restarts a specified number of times, if water pressure recovers to normal, the system enters the normal working state, otherwise, the system automatically shuts down to prevent the pump from idling in the absence of water, and extend the service life of the pump to the greatest extent.
    Application Environment Altitude Less than 1000m, derating above 1000m, 1% per 100m
    Environment Temperature -10 ℃ ~ ± 40 ℃, 40 ℃ -50 ℃ derating, 4% per 1 ℃
    Vibration < 5.9/S2(0.6G)
    Storage Temperature -40℃~ 70℃
    Installation Environment Being dust and splash proof, the product is installed in a place not exposed to direct sunlight.
    Note: Although this product has a high grade of protection, it is not an explosion-proof product, and is not allowed to immerse in water.
    Application of PD20 Pump Drive in a Public Bath Center

    The public bath center in Jixi city is a large-scale leisure facility that integrates bathing, accommodation and catering, where a large amount of water is required. Under this condition, they required frequency conversion constant pressure water supply system to realize automatic operation on the basis of power and water saving. Taking into account the difference in the amount of water required in different functional areas, we have designed a suitable solution tailored to their frequency conversion drive application.

    Features
    • The VFD has a splash-proof enclosure and easy for wiring, which can be directly mounted on the back side of pump, eliminating the installation of the VFD inside the control cabinet and greatly saving space and cost.
    • Each variable frequency pump is operated independently, the pressure can be adjusted and freely set.
    • The system can be operated automatically after being powered on, it eliminates the need for professional electrician and significantly saves labor costs.
    • It is featured by stable pressure, high uniformity of cold and hot water, providing customers with comfortable experience.
