DC Power Supply Voltage Range: DC9-32V2. Signal Input Specifications: Signal Level Amplitude: The output signal level amplitude can be set by the jumper on the board, which can support three general and conventional level controls of 3.3V, 5V, and 24V.3. Load Output Specifications: The LOAD output interface is directly connected to the solenoid coil. 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 0-100% through the on board PWM potentiometer. The frequency of PWM is 2-20KHZ, 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 probeThe 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 30-755 degrees.5. Instant start time of full load outputTIME 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 0-2 seconds adjustable.6. Output frequency working rangeThe PWM frequency adjustment when the electromagnet is working normally, the range is 2-20KHZ. 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 controlThe 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 1/3-1/4 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 30% 10%. 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 protectionThe 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 0.2-15A.9. Install wiring and use settingsThis 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.
