Description
Overview
An intelligent water pump controller (frequency inverter) using SPWM control technology to vary pump speed according to system demand, maintaining set pressure via built-in PID control.
Applications
Pump speed and pressure control for single or multi-pump systems (up to 8 pumps), replacing fixed-speed operation with automatic pressure-matched output.
Operating Conditions/Limits
- Operating temperature: -10°C to 40°C
- Ambient humidity: 0–95% relative humidity (non-condensing)
- Vibration: <0.5G
- Input voltage tolerance: 220V ±15%, 380V ±15%, 525V ±15%
- Frequency range: 0.10–400.0Hz
Performance Range
Power ratings from 0.75kW to 45kW depending on voltage series, with rated current scaling accordingly (see model table). Rated max pump head adjustable 0–250m. Corresponding sensor pressure range 0–200 bar (factory default 10/16/25 bar depending on configuration).
Power Supply
Available in three input configurations: 220V single/three phase, 380V three phase, and 525V three phase, all at 50Hz.
Construction
Available in plastic frame, hanging steel frame, or standing steel frame housings depending on power rating. 5-digit display showing frequency, current, speed, voltage, set pressure, current pressure, and fault status. RS-485 communication control. Digital keypad operator panel with LED run indicator and multi-pump indicator lights.
Available Configurations/Versions
- Three voltage series: 220V (1PH input, 3PH output), 380V (3PH–3PH), 525V (3PH–3PH)
- Multiple frame types matched to power/case size (case 302, 305, 317, 030, 045)
- Optional pressure transducer accessory, available in 0–10 bar, 0–16 bar, or 0–25 bar ranges matched to system parameters
