| 1 | The refrigerating system uses environmentally friendly refrigerant R404a (R449a as option) and R23. Adopting binary low temperature circuit system design, it is convenient to use different compressors for work in different temperature regions. | |
| 2 | Temperature and humidity control using P.I.D + S.S.R system coordinated control with the same channel. It has the function of automatic calculation, which can immediately modify the temperature change conditions to make the temperature control more accurate and stable. | |
| 3 | High-precision controllers of temperature. The relative temperature performance is accurately set and displayed with a resolution of 0.1 ℃. | |
| 2.2 Temperature System | ||
| 1 | Temperature system using Nickel-chromium alloy high-speed heating electric wire; | |
| 2 | High temperature system is completely independent; | |
| 3 | Contains four temperature sensors to detect the surface temperature of the battery and display it on the controller | |
| 2.3 Control System | ||
| Temp. Sensor | High precision PT100 Platinum resistance | |
| Controller | Weintek | |
| Display Function | a. Temp. Setting (SV) Practical (PV) value can be displayed directly b. Display numbers, paragraphs, remaining time and cycles, running time c. Program editing and graphic curve display, d. Fixed or program operation status display, |
|
| Interface | a. RS-232 or R485 port design b. Connected to computer c. Monitor and remote control by computer and Ethernet |
|
| 2.4 Protection System | ||
| 1 | Protection for Electrical leakage | |
| 2 | Over-temperature | |
| 3 | Compressor overvoltage and overload | |
| 4 | Heater short circuit | |
