Wiring diagram 1 and 2
1. When the output end is connected with a large electrolytic capacitor filter, because the voltage at both ends of the capacitor can not change suddenly, such high voltage and large capacitance places are very easy to cause the module over-current and damage. Therefore, before the module is powered on, it is necessary to ensure that the con working voltage at the control end is 0V. After the module is powered on, the con must increase slowly from 0V to ensure the minimum capacitor impulse current.
2. Con must be positive for com. If the polarity is opposite, the output will be out of control (fully open or fully closed). When con of control terminal changes from 0-5V, the working voltage of load can be adjusted from 0V to the highest value (for resistive load). Among them, when con is about 0-0.8v, it is the fully closed area, which can reliably turn off the output of the module; when con is about 0.8v-4.6v, it is the adjustable area, that is, with the increase of the control working voltage, the conduction angle α decreases linearly from 180 ° to 0 ° and the working voltage on the load increases from 0V to the highest value; when con is about 4.6v-5v, it is the fully open area, and the working voltage on the load is the highest value.
3. The input impedance of con to com is higher than or equal to 30K Ω for e, F and H type, and 250 Ω for G type. +5V working voltage signal is only used for manual potentiometer, not for other purposes. The resistance value of the selected potentiometer is between 2-10k Ω. Note: the G type of 4-20mA can not be adjusted manually by potentiometer, and the + 5V terminal has no effect at this time.
4. The load needs linear voltage regulation and voltage stabilization.
5. The calorific value of the whole module is calculated by multiplying the specific load current ampere by 3.0 watts per ampere.
6. The working voltage of the insulation layer between the weak current part, the strong current part and the module bottom plate is greater than 1200vac.
7. Single phase rectifier module can only be used in 50 Hz power grid, among which 220 V series is used in 120-230 VAC power grid, 110 V and 36 V series are used in 50-120 VAC and 20-50 VAC power grid respectively, and 380 V series is used in 180-400 VAC power grid.
