Product Description

About Bedford

Guangzhou Bedford Electric Equipment Co., Ltd. has focused on automatic water pump controllers and solar pump inverters since 2003. We aim to provide users with innovative inverter solutions for stable water supply systems worldwide. It is essential to source quality automatic water pump controllers from a reliable water pump manufacturer to improve the automation level of water supply systems and reduce equipment maintenance and labor costs. The W713B series pump-mounted controller has been recognized and appreciated by our customers since its launch.

Waterproof New Style Constant Pressure Variable Speed Water Pump Controller -IP54
is suitable for full-automatic operation, with characteristics of high quality, multi-functional, low noise and strong commonality etc.There are no special demands for peripherals, it mainly use normal components, for example: Water detection use transducer, transmitter (include water level transmitter, temperature transmitter, etc. ) or inductive remote transmission pressure gauge, with output of 4~20mA, 0~5VDC and 0~10 VDC standard signal.
Features:

Pressure Optimization	Pressure Stability	The pressure change curve is more stable, and the frequency change is smaller after stabilization
	Alternate Transition	Yes, the transition tends to be smooth and excessive (the transitional pump looks at the difference between the given pressure L and the feedback pressure P to adjust the frequency, and it will stop when L-P<0.2bar. If the water consumption suddenly increases at this time, the L-P>0.2 bar, alternating water pumps will speed up the frequency regulation pressure, when L-P=0.2bar, slowly adjust the frequency for a smooth transition)
Mode	Control Mode	Constant pressure, Constant differential pressur,Constant temperature, Constant differential temperature
	Linkage Mode	Synchronize, Master-slave, Big-small pump, One duty one standby, One VFD drive two pumps
	Manual/ auto Mode Switching	Can be switched by button or terminal. Button switch: press the and buttons at the same time for manual/auto switch (also switchable in case of failure) Terminal switching: S2-COM off: auto control S2-COM on:manual control In manual control, the manual frequency can be adjusted through the up and down buttons, and the influence of pressure is shielded, which is more comprehensive
	Alternating Mode	Alternate by time (Alternate when time comes to sleep) Alternate sleep and wake up, and alternate by time
	Upper and Lower Pool Control	Available (S1~S4 terminal control)
	Independent Start and Stop Control	Available, start and stop is controlled by the inverter (can be controlled by panel or S4 terminal)
Outward Expansion	General Frequency Converter (such as PLC)	Compatible with this mode
	Connect the Touch Screen of BEDFORD	Available
	Third-party Devices	Direct connection (Mob Bus RTU communication protocol)
External Interface Features	Analog Input
	Digital Input	4-way 1. Electronic contact gauge control 2. Manual/auto control 3. Terminal run/stop 4. Water level control (low water level) 5. Upper and lower pool control 6. One driving two fault input
	Digital Output	way relay output selection 0: Error or external fault; 1: Forward running (including zero-speed running); 2: Upper limit frequency reaching; 3: Stop status; 4: Lower limit frequency reaching; 5: The frequency is not equal to zero; 6: Actual pressure on the outlet side reaching high water pressure alarm value; 7: Actual pressure on the outlet side decreases to low water pressure alarm value; 8: Actual temperature on the outlet side reaching high water temperature alarm value; 9: Actual temperature on the outlet side decreases to low water temperature alarm value; 10: One driving two RO function, for variable frequency pump control 11: One driving two RO function, for power frequency pump control
