HLP-P Series Fan/Pump Dedicated Frequency Converter / HLP-P系列风机水泵专用型变频器

HLP-P series converter is expressly developed for machines such as fan, pump and air compressor, based on the features of flow and pressure control principle. It can be used in closed-loop system dispense with PLC for its PID controller in most situations. It has functions of automatic voltage regulation, dormancy, automatic energy-saving, automatic stop when overpressure and restart when pressure gets normal, etc.
Specifically, it has an analog input and output expansion board from 15kW upwards, which is designed for three feedback signals from the pressure transmitter.

Power range: 0.75-5.5 kW (1 & 3×220V), 0.75-450 kW (3×380V)

Functions and Features
It has a wider tolerance for the changes of supply voltage;
It can be used one for two, that is one motor is supplied from converter and two motors are supplied from the main line;
It has PID controller which can replace PLC in most closed-loop systems;
It can receive three kinds of feedback signals: resistance 0-400, current 4-20mA and voltage 0-10V;
It has functions of Simple PLC, wobble, quasi winding and unwinding, multi-Speed control, etc;
It provide full protections to ensure that pump has a much longer service life;
The carrier frequency is user definable and can be as high as 20kHz;
It has automatic energy-saving, automatic voltage regulation and dormancy functions
It can automatically stop when the pressure is too high and restart when the pressure gets normal;
It has Holip Communication Protocol and Modbus Protocol, and it is easier for user to build up centralized control system.
