The output LOAD+ is connected to the power supply+, LOAD is a high power NPN output interface, the control method is PWM, and the duty cycle is adjustable from 0100percent through the on board PWM potentiometer. The frequency of PWM is 220KHZ, which is adjusted by the FRQ potentiometer on the board. The maximum output working current is 15A. The output interface has an LED indicator.
4. Output over temperature protection and NTC thermistor probe
The product is designed with a temperature probe, which can be used to detect the temperature of the load or the temperature of the product itself. If the temperature is higher than the set value, the output is stopped. The probe parameters are: NTC thermistor, 3950 temperature curve model. The resistance value is 10K ohms. The temperature setting is set by the OTP over temperature protection potentiometer on the board, and the range is 3075+5 degrees.
5. Instant start time of full load output
TIME instant start time setting potentiometer can set the duration of the electromagnet start up full current output. That is, when the electromagnet is started, the maximum current is used to start the electromagnet, and the working time of this maximum current. The potentiometer can be set for 02 seconds adjustable.
6. Output frequency working range
The PWM frequency adjustment when the electromagnet is working normally, the range is 220KHZ. Different electromagnets have different mechanical resonance points. If the operating frequency is exactly the same as the resonance point of the electromagnet, the electromagnet will vibrate and emit a lot of noise. In order to solve the vibration and noise when the electromagnet is working. Therefore, the operating frequency must be designed to be adjustable. According to different types of electromagnets, adjust the FRQ frequency potentiometer to make the electromagnet work noise disappear.
7. Internal PWM duty cycle control
The PWM Duty Cycle Potentiometer Can Adjust The Locking Strength Of the electromagnet. The principle is to adjust the strength by adjusting the working current through PWM. The greater the strength and the greater the current, the greater the heat generation. For general electromagnets, adjusting to 1314 of the design current value can maintain the electromagnet in a locked state. The strength is different from the requirements, please decide by yourself. According to experience, the general electromagnet is powered by its nominal voltage power supply, and the current is about 30percent + 10percent . The standard is: As long as the maximum strength of the electromagnet does not exceed 65 degrees after working for half an hour.
8. Output current limit protection
The current limiting protection setting potentiometer is used to set the maximum operating current point of the output. Exceeding the set point is limited to this point, and the current output is not allowed to exceed the set current. To achieve the function of overcurrent protection. The setting range is 0.215A.
9. Install wiring and use settings
This product is mainly used to drive and control electromagnets, solenoid valves and other devices that convert electrical energy into pwm magnetic energy. Make this kind of device control more intelligent. When driving this type of device, it has the following characteristics:
a. When electromagnetic parts such as electromagnets and solenoid valves are energized for a long time, the working parts do not heat up. Solve the problem that ordinary electromagnets cannot be energized for a long time. When the conventional electromagnet is energized for a long time, the coil will generate heat. When the heat reaches a certain level, the magnetic core of the magnetic field will be magnetically saturated. The higher the temperature, the lower the magnetic saturation point, so the magnetic field will be smaller and weaker. When the temperature reaches the highest point that the coil can withstand, the coil will be damaged. Therefore, the general electromagnet cannot be energized for a long time.
b. It can control the thrust and lock strength of the electromagnet. By adjusting the PWM pulse width potentiometer on the board (0100percent PWM adjustable), you can control the strength of the electromagnet on the board. Adjust the FRQ frequency potentiometer (1.8KHZ20KHZ), you can adjust the operating frequency point of the electromagnet, used to match the working frequency and working noise of different types of electromagnets. 2 potentiometers can be combined and adjusted to match Various types of electromagnets.
c. Simple control. Just connect 4pcs wires, power supply positive and negative POWER+ and 2 positive and negative control wires, SIN+ can support NPN or PNP wiring. (Ie common anode COM+ or common cathode COM wiring) 3.3v, 5v, 24v control input, if the control level is 12V level, set the same setting as 24V.
D. Working Principle: At the moment of power on, if there is a control signal, the drive board will start the electromagnet with the maximum thrust designed by the electromagnet. When the electromagnet is stable, the electromagnet enters the lock working state, and the lock force is changed by the PWM potentiometer on the board. control. Generally speaking, when the locking force is set at about 25percent 40percent of the maximum force, the electromagnet can be locked stably, but different types of electromagnets will be different, so you can adjust it according to actual needs.
e. OCP over current protection, OTP over temperature protection function, OCP over current protection is used to prevent load short circuit protection, you can set potentiometer adjustment, over current protection point (current protection setting range is 0.2A15A).

Note:
The over temperature protection function can be used as a probe by connecting an external 3950NTC 10K thermistor. Fix the probe on the load and detect the temperature of the load. If the temperature is too high, the circuit will stop the output. After the temperature returns to normal, the output automatically recovers. The over temperature point can be set via the on board potentiometer.[HIGH SPEED RESPONSE] The electromagnetic actuator control board has high speed response time, input and output delay is less than 20ms.
