Features:
1. Small volume, waterproof, anti vibration, no noise, no contact arc;
2. Photoelectric isolation, long service life, strong anti-interference, high reliability;
3. It can be matched with the output signal interface of temperature control instrument and microcomputer;
4. The module output interface can trigger any unidirectional and bidirectional SCR;
5. It is suitable for analog power regulation, including resistive load, inductive load, transformer, etc.
Control voltageucon and thyristor output conduction angle α curve (resistive load) and waveform diagram:
1. This module can select four signal input control modes:
a. 4-20mA input, COM corresponds to the negative end of control input.
b. 0-5vdc input, COM corresponds to the negative end of control input.
c. 0-10vdc input, COM corresponds to the negative end of control input.
d. The 2-10k potentiometer is input manually, and the + 10VDC terminal on the voltage regulating module provides power for the manual voltage regulating control potentiometer (not for other purposes here).
2. The voltage phase on the tilting load at the end of ① and ② must be consistent with the voltage phase at the end of ③ and ④, otherwise it is out of control, and the power grid frequency must be 50 Hz.
3. The input power supply of the AC voltage regulating module can be 36vac, 110VAC, 220VAC and 380VAC. The user should inform our company of the type selection, so as to avoid damaging the module by selecting the wrong voltage level.
4. The negative polarity of input control signal terminal shall not be reversed, otherwise the output load terminal will lose. When the input control signal is changed, the output voltage can be adjusted from 0 to the maximum ＆#118alue (for resistive load).
5. This single-phase AC voltage regulating module can only be used for single-phase motors of fans and pumps when the requirements are not high.
6. Three single-phase voltage regulating modules cannot be used in three-phase power grid to regulate three-phase load.
7. The working calorific ＆#118alue of the module is calculated according to the actual current * 1.5w/a, and the corresponding equivalent radiator must be equipped.
