Product Description

 

1, the main features

▲ single-phase cooling fans control box.
▲ For the convenience of remote control transformer, control box were output over temperature alarm, over-temperature trip and the fans start and stop the three FET signal.
▲ When the temperature alarm value, the control box with audible alarm.
▲ control box on the cooling fan motor has short circuit protection, overload and under voltage protection to ensure the safe operation of the fan.
▲ control box can output three-way independent of the 4 ~ 20mA analog current, enabling remote communication with the host machine, can increase all the way platinum resistance dry-type transformers used for measuring room temperature.


Third, technical indicators

1, measurement range: 0.0 ~ 200.0 ℃ (sensor Pt100)
2, measurement accuracy: Universal: 0.5 Resolution: 0.1 ℃
3, using the conditions: ambient temperature -20 ~ +55 ℃ Relative humidity <85%
                          Single-phase 220VAC power supply
                          Power frequency 50Hz ± 2Hz
4, anti-jamming performance: the common-mode 250V (AC, 50HZ) or series mode 200mV (AC, 50HZ) interference voltage, the display changes less than the basic error.
5, shows the value of digital compensation range: ± 19.9 ℃
6, instrument warning, protection: open circuit alarm sensor alarm sensor fault self-test
                                               Watchdog function of input over-range alarm
7, relay contact outputs: fan contact capacity: 16A/250VAC
                                      Trip contact capacity: 9A/220VAC, 5A/220VDC
                                     The remaining control output capacity: 7A/250VAC
8, equipped with a fan motor capacity: ≤ 4KW
9, the control box Dimensions: 320 × 260 × 110mm (H × W × D)

Type and Classification of Function

Type

Function

Type D

(Ordinary type)

Three-phase circular measurement; Three-phase circular display/maximum value display and mutual switching between two functions; Input disconnection and trouble self-check display and output; Auto start and stop of cooling fan and output; Over-temperature alarm display and output; Over-temperature tripping display and output; Display of manual/auto modes of fan, output and mutual switching; Digital compensation for value displayed in each channel; Function of "black box"; Timed start, stop and control function of fan;  Detection of output status.

Type E

The same as Type D, with addition of 4~20mA analogue current output.

 Type F

The same as Type D, with addition of RS485 serial communications function.

 Type G

The same as Type D, with addition of one-way transformer room temperature measurement and control.

 Type I

The same as Type D, with addition of one-way transformer core temperature measurement and alarm.

Type L

The same as Type D, with addition of protection and alarm function for lack of phase and failure of fan.
