Product Description

With superior performance and muti-function,WLD190 series is integrated
single-pump economic intelligent controller special designed for water pumps.

WLD190 series is economical intelligent controller ,which is specially designed for water users and single pump.Can be directly mounted on the pump motor due to its compact structure .Can set parameter via operation keypad and then automatically run by constant pressure according to water consumption .With characteristics of superior performance and powful function,low noise and versatility , can be used for various occasions,improving the stability of water supply system.

Input Voltage & Output Power Range:
Input:1PH 220V 50/60Hz
Output:3PH 0~220V:0.75~2.2KW & 1PH 0~220V 0.75~1.5kw

Features:
Automatically control and constant water pressure
Built-in PID control method can realize none load shut down(sleep down)
Dry water protection and stop automatically when no water consuming
Power restart automatically after power off
Real-time fault parameter record for analysis
Pressure detection can use the output signal for 4 ~ 20mA, 0 ~ 5.0VDC standard signal pressure sensor, transmitter(including water level transducer, temperature transmitter etc.)

Protection Function:
Over-voltage and low-voltage protection
Output short-circuit protection
High-water pressure and low-water pressure protection
Output phase failure protection
Over-load protection
Sensor open-circuit protection

Environmental Requirement:
Environment temperature range: -10ºC~+40ºC. Controller will be derated if ambient temperature exceeds 40ºC.
Prevent rain drops, moist environment, oil fog, salt erosion, corrosive gas,  etc.
Prevent violent vibration or sudden impact.
Lower than installation altitude, it will be derated is higher than1000m.

Application:
Business:such as office buildings,shopping malls,hotels etc.
Public Field:Such as hospitals, schools, gyms, airports, golf course etc.
Agriculture:such as irrigation, farms, orchards etc.
Manufacturing:Manufacturing, washing equipment, food industry, workshop etc.
Residents Living Water: such as residential quarters, villas etc.
