Product introduction:
The fully isolated single-phase AC voltage regulating module (hereinafter referred to as the single-phase voltage regulating module DTY) is a synchronous transformer, a phase detecting circuit, a phase shifting trigger circuit and an output thyristor. When the control voltage is changed, the output can be changed. The trigger phase angle of the thyristor is the voltage regulation of the single-phase alternating current. According to the output thyristor device, a common type of two-way thyristor, two unidirectional thyristor anti-parallel enhancement type and one unidirectional thyristor half-wave type are classified into three types. According to the rated voltage of single-phase AC load, it is divided into 220V and 380V. According to the different control signals, it is divided into four categories: E, F, G, H, etc. The following is the specification model table: (Note: The current level is the internal thyristor of the module. Maximum current RMS)

Application:
12 is the output, the corresponding random solid-state relay output, the voltage level is 380VAC, can be used on the grid less than 420Vac. According to the different internal controllable silicon of the module, it is also divided into common type, enhanced type and half-wave type. The half-wave type is a one-way thyristor as an output contact, which only regulates the positive half cycle of the AC voltage (the anode of the unidirectional thyristor of the module is connected to the 1st end, and the cathode is connected to the 2nd end).
34 is the module's internal synchronous transformer primary, divided into 220VAC and 380VAC two specifications: 220VAC module allows the use of the grid in the 165-240VAC range, 380VAC module allows the use of the grid on the 285-420VAC, 34 not the same name .
COM is the internal ground, CON is the control end, and the +5V end is internally generated, and only the power supply unit is used for manual control. The strong part of 1234 and the weak part of +5V, CON, and COM are fully isolated.

Current capacity selection
|
①For resistive load, the current rating of the SSR should be greater than or equal to 2 times the rated current of the load.
|
②When the load is an AC motor, the current rating of the SSR must be greater than or equal to 6-7 times the rated motor current.
|
③When the AC electromagnet, intermediate relay line protection, and inductor coil are loaded, the current rating of the SSR should be greater than or equal to 4 times the rated current of the load.
|
④For power compensation capacitors, the current rating of the SSR must be greater than 5 times the rated current of the load.
|
⑤The transformer is required to be greater than or equal to 5 times the primary rated current of the transformer. For special inductive and capacitive loads, the current margin of the SSR must be amplified according to actual experience.

Precautions:
1. If the voltage applied to the load by①②is inconsistent with the voltage of③④, please declare the voltage of the two, our company can customize for the user, but the phase must be the same, and 34 must be 220VAC or 380VAC, 50HZ Voltage level. There are no polarity in①②or③④rooms. For example, a rated voltage of a load is 36VAC (220V power grid is stepped down by a transformer). If a single-phase voltage regulator module of 75A is selected, the module of model TY-H36D75P-220 can be customized to our company,①②of which are connected in series with the load. Received 36V grid,③④feet connected to 220V grid.
2. CON must be positive for COM. If the polarity is opposite, the 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 value (for resistive loads). Where CON is in the fully closed region at 0-0.75V, the output of the module is reliably turned off; CON is adjustable in the range of 0.75V-4.75V, that is, the conduction angle α is from 150 as the control voltage increases. The linearity decreases from ° to 0°, and the voltage on the AC load increases from tens of volts to the maximum value; when CON is about 4.75V-5V, it is the fully open region, and the voltage on the AC load is the maximum value.
3. The input impedance of the E, F, and H series CON to COM is greater than 30KΩ, and the input impedance of the G series CON to COM is 250Ω. The +5V voltage signal is only available to the manual potentiometer. It is not used for it. The potentiometer used is between 2-10KΩ.
4. The speed regulation of single-phase AC asynchronous motor should generally adopt frequency converter. Only soft characteristic load such as fan and pump motor, or torque motor can be adjusted by voltage regulation.
5. Three single-phase voltage regulator modules cannot be used to regulate three-phase loads on a three-phase power grid (see three-phase voltage regulation).
6. The insulation voltage between the weak current part, the strong electric part and the module bottom plate is greater than 2000VAC.
7. The heat output of the whole module is calculated by the actual current amperage of the load by 1.5 watts/ampere. The radiator can be selected with E-40, F-70, F-100 and G series.
8. Please refer to the single-phase AC solid state relay for the selection and protection of the current level.
9. If the load has high linearity and voltage regulation requirements, please increase the voltage negative feedback module.
