Input

Thermal resistance and thermocouple

Communication function(purchasing)

RS-485 interface with local and remote communication function, monitoring software, RS-485/RS-232 convertor, one COM interface and one USB interface occupying PC computer; connect 16 sets of equipment at most; and the maximum accumulated length of the cable is 800M

Control mode

Anti-integration saturation PID

Curve recording function

RAM with battery protection: it can save the setting value, sampling value and sampling time of equipment; and the maximum recording time is 350 days(when the sampling period is 1.5min)

USB function

It is equipped with one U-disk and software disk special for PC computer(applicable for complex Chinese, English WINDOWS operation system); the test program is compiled by PC special software and saved in U-disk; and then the test program is tuned out from the U-disk and saved in the controller; or the program in the controller is saved in U-disk and then it is saved in PC machine to be analyzed and managed.The test curve data saved in the controller can be saved in U-disk.The test data/curve is directly printed and displayed by PC special software; or the recorded data is converted to Access data file read by Microsoft Office.The test curve data recorded by the recorder is as follows: two-circuit temperature-seting temperature and actual temperature; two-circuit humidity-setting humidity and actual humidity(if the equipment has humidity function); record the time.

Auxiliary function

Fault alarm and reason, treatment prompt function, power failure protection function, and upper and lower temperature limit protection function; calendar timing function(automatic starting or automatic stopping); self-diagnostic function

Water supply

Humidity system

Equipped with muli-level filter reverse osmosis water purifier(users provide humidification water with resistance rate ≥ 500Ω m

Cooling circulating water

Water supply pressure: 0.32~0.45MPa water temperature: ≤ 30℃

Power

AC 380V(± 10%)V 50HZ three-phase four-wire+protection ground wire

Installed capacity

20KW~55KW（it is different according to different models and configurations）

Standard configuration

Observation window, wire hole, floodlight, time accumulator, one power wire(6m long), one sample power control terminal, one RS-485-232 interface, one USB and one U-disk

Safety device

Refrigerating system: over-voltage of compressor, over-heating of compressor, over-current of compressor motor, water supply and under-voltage of cooling water(water cooling); humidifying system(SQW model): dry burning of heating tube, abnormal water supply and abnormal water drainage.

Test chamber: over-temperature protection, temperature fuse wire, over-heating of fan and motor, others: phase sequence of total power and lacking protection, leakage protection and load short circuit protection.
