SL1600-TH3 High precision lab A/C controller
Compatible unit
 

1-2 compressors high precision lab A/C Controller
Function
 

*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.
