The model for the input control signal type, E 0-5V; F said 0-10V; G 4-20mA; H 1-5V.
Full isolation single-phase AC voltage regulator module (hereinafter referred to as the single-phase voltage regulating module DTY) is a set of synchronous transformer, phase detection circuit, phase shift trigger circuit and output SCR in one, when changing the control voltage of the size, you can change the output triggering angle, namely single alternating current voltage regulator. According to the output silicon controlled devices, there are three types of silicon controlled rectifier, one is bidirectional thyristor, the other is unidirectional silicon controlled rectifier, and the other is one-way silicon controlled rectifier. According to the rated voltage of single-phase AC load 220V and 380V two categories, according to the control signal of different E, F, G, H type and other four categories, the following specification model: (Note: current level is the internal SCR maximum current effective value)

Note: the type of input control signal type, E 0-5V; F said 0-10V; G 4-20mA; H 1-5V.
|E series||F series||G series||H series|
|Effective input range||0.75~4.75V||1.5~9.5V||5~19mA||1.25~4.75V|
|Range of phase shift angle||150°~0°||150°~0°||150°~0°||150°~0°|
The output voltage level is 380VAC, which can be used in the power grid less than 420Vac. According to the different thyristor in the module, like the solid state relay, it can also be divided into ordinary, enhanced and half wave type. The half wave mode is a one-way silicon controlled rectifier as the output contact, only the positive half cycle voltage adjustment of the AC voltage (the inner module of the unidirectional thyristor is connected with the anode, the end of the cathode).
(3) for the internal synchronous transformer of the module, 220VAC and 380VAC are divided into two specifications: the 220VAC module is allowed to use in the power grid of 165 - 240VAC, and the 380VAC module is allowed to use in the power grid of 285-420VAC.
The COM is the internal terminal, the CON is the control end, and the +5V terminal is internally generated for manual control of the potentiometer. The weak part of the strong electricity part and the +5V, CON and COM are all isolated.
|Half wave mode||Airport combination for electric shock|
|Ordinary type||Low current module or dv/dt requires lower occasions|
|Enhancement type||High current module or dv/dt requires higher occasions|
|220V||220V loop load|
|380V||380V loop load (i.e. two firing lines added to the load)|
|Current capacity selection||When the resistive load is selected, the current rating of the SSR should be more than or equal to 2 times the rated current of the load.|
|When the load is an AC motor, the current rating of SSR must be greater than or equal to 6-7 times the rated current of the motor.|
|When the alternating current electromagnet, the intermediate relay line protection, the inductance coil and so on load, selects the SSR current class to be supposed to be more than or equal to 4 times the load rated current.|
|When the load of power compensation capacitor is selected, the current rating of SSR must be more than 5 times the rated current of the load.|
|Transformer should be more than or equal to 5 times of transformer primary rated current. Special inductive capacitive load should be enlarged according to the actual experience of SSR current margin.|
The single phase AC voltage regulator module can select the following radiators:
1. If the voltage on the load is not the same as that of the voltage at the third level, the user can declare the voltage of both of them. The company can customize the voltage for the user, but the phase of the two must be the same, and the voltage level of 220VAC or 380VAC and 50HZ must be the same. There was no polarity between the two groups. For example: a load rated voltage of 36VAC (220V power grid step-down through the transformer), select 75A single-phase voltage regulator module, can be customized to our company model TY-H36D75P-220 module, in which one foot and load series connected to the 36V power grid, and the third foot connected to the 220V grid.
2, CON must be positive for COM, if polarity is opposite, output is out of control (fully open or fully closed). When the control terminal CON changes from 0-5V, the voltage on the AC load is adjustable from 0 volts to the maximum (for resistive load). The CON is about 0-0.75V in the fully closed area, reliable output shutdown module; CON in 0.75V-4.75V for adjustable region, with the increase of the control voltage, conduction angle decreases from 150 DEG to 0 DEG linear, AC voltage on the load from tens of volts increases to a maximum at about 4.75V-5V CON; when the open area, AC voltage on the load is the maximum value.
3. The input impedance of E, F and H series CON is greater than 30K, and the input impedance of G series CON to COM is 250 ohms, COM. +5V voltage signal is only provided for manual potentiometer, not for it, the selected potentiometer resistance is between 2-10K ohms.
4, single-phase AC asynchronous motor speed control should usually use frequency converter, only fan, pump motor and other soft characteristic load, or torque motor situation can be adjusted by pressure to achieve speed regulation.
5, three single-phase voltage regulator modules can not be used in three-phase power grid for three-phase load voltage regulationThree phase voltage regulation）。
6. The insulation voltage between the weak current part, the strong current part and the module bottom plate is greater than 2000VAC.
7. The heat output of the whole module is calculated by 1.5 watts / ampere according to the actual ampere current of the load, and the radiator can choose E-40, F-70, F-100 and G series
