The PDG10 Series Smart Pump Drive is a multi-purpose water pump speed control product independently developed by SAJ. It is installed in the electric control cabinet and can be connected to various senor signals such as pressure sensors, remote pressure gauges and pressure switches. The system is simple in operation, high in reliability, low in noise, and cost-effective. Each pump is equipped with a pump drive, which can realize multi-pump smart on-line operation.

2 way of output, programmable
1 way of output, programmable
Command running channel：
Three kinds of channels: 1. operation panel 2. control terminal 3.serial communication port, choose 1 and 2 for host drive and 3 for auxiliaries
Multi-Pump Smart Link：
One drive in the system can be host and controls auxiliaries(4 at most) to work by communication mode. Host sends PID feedback to auxiliaries and monitors status of auxiliaries in real time. If failure occurs, the auxiliary will be skipped.
Advanced PID arithmetic to realize closed loop control system
When grid voltage changes, it keeps output voltage constant automatically. By default, it doesn’t work at deceleration.
Automatically limit current and voltage at running period to prevent tripping caused by frequent overcurrent/overvoltage.
Water shortage protection：
Controller detects that pipe network pressure is lower than water shortage pressure, system stops working automatically. After set period, it restarts automatically for specified times. If pressure restores to normal, system works normally. Otherwise, system stops automatically in case of idle running of pump and prolongs pump lifetime in maximum.
High pressure alarm：
When pressure exceeds set pressure, it stops automatically to prevent pipe network from high pressure.
Automatic energysaving running：
Decrease output voltage automatically at light load to save energy.
4-bit password can be set with non-zero numbers. Exit password setting interface and the password will be valid after 1 minute.
Define whether the parameter is locked in running or stopped state in case of misoperation.
Installation environment should have be without direct sunlight, dust,corrosive gas, inflammable gas, oil mist, steam, water drop
