Output frequency range: the default is 30HZ-10KHZ. (According to the input voltage, the output frequency will change, the two are proportional relationship);
the installation of fixed: 4 * M3 screw hole.
the use of instructions and wiring (reference the picture).
Features:
1. Power supply has anti-reverse function.
2. Power on the power indicator light.
3. By adjusting the potentiometer on the board, you can match the calibration of different voltage and frequency of the corresponding relationship.
4. The output voltage of this module can be adjusted as needed. The output frequency is adjusted according to the input voltage change.
5. Duty ratio of about 50%, with the frequency changes will change.
The correspondence between voltage and frequency is as follows:
0.5V = 500HZ,
1V = 1KHZ,
2V = 2KHZ,
.................... 9V = 9KHZ,
10V = 10KHZ,
If the voltage at 1.1V, the output frequency is 1.1KHZ. The accuracy of this module can be 0.1V DC voltage into 100HZ.
Such as: If the power supply access 12V, the input signal is DC3.6V, the output is 3.6KHZ square wave, the output amplitude (12V * 0.7) 8.4V to 0V adjustable between the peak and peak.
12V power supply, the default signal output, we will be located in about 6V. This output will vary depending on your supply voltage. The frequency varies with the level of the control voltage and does not vary with the power supply.
Duty cycle: varies with the input voltage
6. The module output can be used to make the driver pulse signal, and the drive with a total of when the anode connection, the relevant wiring is
OC-OUT: Connect the PUL- or PUL of the drive
12-30V: then the driver PUL + or common +5 V, (12V power supply, to string a 330R resistor, 24V power supply, to string a 2.7K resistor current limit)
