*Four control modes for humidifier, integrate humidifier precision control. *Build-in phase protection function. *Intelligence control of the temperature and humidity to achieve a balance environment. *Advance fuzzy algorithms, more accurate and stable to detect the current. The precision can reach to±2%,the mistake rate will less the 0.1%. *Up to 6 units control, duty standby function, in order to enhance the stability. *Suitable for different units: Air-cooled, Water cooled, selectabled on the controller board via dial switch. *Max /Min temp.and humidity can be set easily, flexible used, suitable for different environment. *Water coil cooling and compressor cooling selectable. *Suitable for 2-46Kg/h three-pole or six-pole cylinder, proportional inlet and outlet water. High precision control. *Drain time settable. Timer clean function. *High water level alarm, Soft water quality alarm, low current alarm. *Control heating by 0-10V SCR, Support 0-10V VFD control. *Support auto restart function, support terminal chain control. *Trial run function; Memory function; Supply air temperature high, low protection; Probe fault protection. *Strong stability, 0.15-80MHz interference rejection, 4KV high voltage and surge resistance *SMT technology, 48 hrs burn-in test for ensuring quality *MODBUS-RTU RS485 Widely-used communication protocol, up to 1km max distance (Gateway Free); *PCB Surface painted with CRC, avoid leakage, short circuit, and erosion from acid/ alkali/ alcohol/ humidity/salt spray; *Featured with tension and torsion resistance probe, long working life *Wide voltage range, avoid misoperation caused by voltage fluctuation *Control logic implemented on the control board. Continue working even HMI has fault.
