SAJ 11kw Variable Frequency Drive for Water Pump Motor Speed Controller
PDG10 Series Smart Eco Pump Drive
PDG10 series wall mounted (cabinet) pump dedicated drives are smart all-in-one water supply products developed independently by SAJ. It is installed in the electric control cabinet and can be connected to many kinds of sensor signals such as pressure sensors, transmissible pressure gauges and pressure switches. The system is easy to operate and cost effective with high reliability and low noise. Each pump is equipped with a pump drive, which can realize multi-pump(host and auxiliary pumps) linked operation.
Two-way communication extension performance
1. Standard dual RS485 interface for On-line monitoring purpose
2. Standard dual relay, one drive two rotation
3. Standard dual analog, current voltage change at will
Multi-Pump Smart Link, easy setting
1. Only a network cable is needed to combine multiple pumps.
2. One key setting to realize multipump linkage constant pressure water supply
Dedicated water supply function
1. Single-point/multipoint pressure detection, more precise and energy saving
2. Dedicated control: dormancy, water leakage, automatic running recovery
3. Dedicated protection: water shortage, antifreezing, alarm at high and low pressure
Wide applicability
1. General product design
2. Wide power range 0.75-400kW
3. Stable and reliable
4. Panel control function, apply to fan and water pump
Application1. Non-negative pressure water supply system
2. Secondary booster water supply system
3. Water treatment, water circulation system
4. Air conditioning cold water and warm water system

| Basic functions | 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. |
| Integrated PID | Advanced PID arithmetic to realize closed loop control system |
| AVR | When grid voltage changes, it keeps output voltage constant
automatically. By default, |
| it doesn't work at deceleration. |
| Stall control | Automatically limit current and voltage at running period to
prevent tripping caused by frequent |
| overcurrent/over voltage. |
| 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 energy- | Decrease output voltage automatically at light load to save energy. |
| saving running |
| Password setting | 4-bit password can be set with non-zero numbers. Exit
password setting interface and the password |
| will be valid after 1 minute. |
| Parameter lock | Define whether the parameter is locked in running or
stopped state in case of misoperation. |
| Application environment | Installation environment | Installation environment should have be without direct sunlight,
dust, corrosive gas, inflammable gas, oil mist, steam, water drop |
| Altitude | Lower than 1000m, service in derated capacity above 1000m.
Derate 1% capacity every |
| 100m increase in height. |
| Environmental temperature | -10ºC ~ +40ºC, service in derated capacity for 40ºC ~ 50ºC.
Derate 4% capacity every 1ºC |
| increase in temperature. |
