DC Fan Temperature Control Governor PWM Chassis Fan Speed Regulator 12V 24V 2A

Description

☆ Welcome☆ to ☆ my ☆ shop ☆
This JCF2404 temperature control governor uses PWM modulation technology to achieve temperature control. The governor controls the speed of the fan according to the ambient temperature. The higher the temperature, the faster the speed. The ambient temperature is lower than the set startup temperature. When the speed governor controls the fan to stop running.
Features:
1. Dual-mode operation (fixed temperature range + adjustable temperature), high power, maximum support 4A current fan access
2. Support various 2 3 4 wire DC fan speed regulation, users can achieve temperature control speed regulation without buying expensive 4 wire PWM fan.
3. The use of industrial-grade PWM speed regulation chip and frequency conversion technology, stable performance and accurate control, eliminating the large radiator of ordinary linear speed regulator, lower power consumption, higher efficiency, and save installation space.
4. Dynamic LED indicator, intuitive and real working status of demodulator.
5. Most of the devices use SMD packaging, stable performance, small size and save space.
6. The temperature probe is sealed with epoxy resin, waterproof and moisture-proof, with mounting holes on the top of the probe for easy installation.
7. Fixed mode: The startup temperature is fixed at 30 degrees, the fan speed increases linearly from 30 to 50 degrees, and the fan runs at full speed above 50 degrees
8. Adjustable mode: The range of starting temperature is adjustable from 10 to 50 ° C (full speed temperature = starting temperature + 20 ° C)
9. The maximum temperature of the temperature probe is 110 degrees, exceeding this temperature probe will be damaged
The temperature probe is made of 1% high-precision thermistor with epoxy seal, which is waterproof and moisture-proof. The metal part of the probe is a temperature sensing point. The length of the connecting wire is 30cm by default. You can use a wire to extend it! Fix the probe to a heat source during use.
The governor is designed with high power and double voltage range. No matter what type of fan, no matter how many lines the fan has. Just make sure the voltage of the fan is 12V / 24V and the current is within 2A. The voltage version of the governor must be consistent with the voltage of the fan, and the current of the governor must also be consistent with the current of the fan.
How many fans can a governor connect to
Number of fans connected = current version of governor / current of single fan
For example, the customer orders the 2A version, if the fan current is 0.5A;
Number of connected fans = 2A / 0.5 = 4
Instructions:
1. Connect the power and fan wiring according to the interface instructions
2. Plug the temperature probe into the governor, and fix the metal part of the probe to the heating place
3. Turn on the power. The governor will adjust the fan speed according to the temperature detected by the temperature probe.
4.About the use of fixed mode and adjustable mode
4.1: In fixed mode, set the No. 10 switch to the F position, and the startup temperature of the governor becomes 30 ° C. When 30 ~ 50 ° C, the fan speed increases with the temperature, and when the temperature reaches 50 ° C, the fan runs at full speed.
4.2: Adjustable mode. Turn the No. 10 switch to the A position. At this time, the temperature range of the governor is set by the No. 11 potentiometer.
4.2.1: When leaving the factory, the No. 11 potentiometer is in the middle position (the corresponding starting temperature is 20 degrees)
* Turn the potentiometer No. 11 slowly counterclockwise, and the startup temperature of the governor will slowly decrease.
Turn it to the end, the corresponding starting temperature is 10 degrees,
* Turn the No. 11 potentiometer slowly clockwise to increase the startup temperature of the governor.
Turn it to the end, the corresponding starting temperature is 50 degrees,
The potentiometer No. 11 is rotated from the left to the middle position (clockwise), and the starting temperature is evenly changed from 10 to 20 degrees
* The potentiometer No.11 is rotated from the middle position to the far right (clockwise), and the starting temperature changes uniformly from 20 to 50
This governor completely adopts industrial-grade technical solutions and is suitable for industrial control environments.
1.Energy saving and noise reduction of fans in outdoor enclosures and cabinets
2. Machine room fan energy saving and noise reduction
3.Other fan temperature control and speed regulation applications
