Product Description Fully isolated single-phase AC voltage regulator module DTY-H220D75E DTY-H220D75F DTY-H220D75G DTY-H220D75HThe last digit of the model is the input control signal type, E means 0-5V; F means 0-10V; G means 4-20mA; H means 1-5V. Fully isolated single-phase AC voltage regulation module (hereinafter referred to as single-phase voltage regulation module DTY) is a synchronous transformer, phase detection circuit, phase shift trigger circuit and output thyristor in one, when the size of the control voltage is changed, the output can be changed The triggering phase angle of the SCR can realize the voltage regulation of single-phase alternating current. According to the different output thyristor devices, it is divided into three types: a common type of bidirectional thyristor, an enhanced type with two unidirectional thyristors in anti-parallel, and a half-wave type with one unidirectional thyristor. According to the rated voltage of single-phase AC load, it is divided into two categories: 220V and 380V, and four categories according to the different control signals: E, F, G, H, etc. The following is a table of specifications and models: (Note: The current rating is SCR inside the module Maximum current effective value)2 Model list Types ofElectric currentChoose one of 220V loadlast E\F\G\HChoose one of the last E\F\G\H of 380V load Enhanced15ADTY-H220D15EDTY-H380D15E35ADTY-H220D35EDTY-H380D35E55ADTY-H220D55EDTY-H380D55E75ADTY-H220D75EDTY-H380D75E120ADTY-H220D120EDTY-H380D120E150ADTY-H220D150EDTY-H380D150E190ADTY-H220D190EDTY-H380D190E240ADTY-H220D240EDTY-H380D240E290ADTY-H220D290EDTY-H380D290E350ADTY-H220D350EDTY-H380D350Enormal type10ADTY-220D10EDTY-380D10E25ADTY-220D25EDTY-380D25E40ADTY-220D40EDTY-380D40EHalf-wave10ADTY-220D10XEDTY-380D10XE25ADTY-220D25XEDTY-380D25XE50ADTY-220D50XEDTY-380D50XENote: The last digit of the model is the input control signal type, E means 0-5V; F means 0-10V; G means 4-20mA; H means 1-5V.

According to the difference of thyristor inside the module, it is also divided into ordinary type, enhanced type and half-wave type like solid state relay. The half-wave type is a unidirectional thyristor used as the output contact, and only regulates the positive half cycle of the AC voltage (the anode of the unidirectional thyristor inside the module is connected to the 1. end, and the cathode is connected to the 2.end).3.4.It is the primary part of the internal synchronous transformer of the module, which is divided into two specifications of 220VAC and 380VAC: the module of 220VAC specification is allowed to be used on the power grid in the range of 165-240VAC, and the module of 380VAC specification is allowed to be used on the power grid of 285-420VAC, 3.4. regardless of the end of the same name .COM is the internal ground terminal, CON is the control terminal, and the +5V terminal is internally generated. It is only used for manual control of the power supply. The strong current part of 1.2.3.4. is fully isolated from the weak current part of +5V, CON and COM.Half-waveUsed for electric shock airport closurenormal typeSmall current module or dv/dt with lower requirementsEnhancedHigh current module or dv/dt demanding occasions220V220V loop load380V380V loop load (that is, add two live wires to the load)Current capacity selection1. For resistive loads, the current level of SSR should be greater than or equal to twice the rated current of the load.2.When the load is an AC motor, the current level of SSR must be greater than or equal to 6-7 times the rated current of the motor.3. For AC electromagnet, intermediate relay wire protection, inductance coil and other loads, the current level of SSR should be greater than or equal to 4 times the rated load current.4.When compensating for capacitor-type loads, the current level of SSR must be greater than 5 times the rated current of the load.5. The transformer requires 5 times or more of the transformer primary rated current, and the special inductive and capacitive loads should also amplify the SSR current margin according to actual experience.The single-phase AC voltage regulation module can be equipped with the following radiators: E-40/F-70/F-100/G-120/G-150/G-185/A-250/A-330 1. If the voltage applied to the load through 1.2. is inconsistent with the voltage of 3.4., please declare the voltage of the two, our company can customize it for the user, but the phase of the two must be the same, and 3.4. must be 220VAC or 380VAC, 50HZ Voltage level. There is no polarity between 1.2.room and 3.4.room. For example: if the rated voltage of a load is 36VAC (the voltage is reduced by a 220V power grid via a transformer), if a single-phase voltage regulation module of 75A is selected, a module of type TY-H36D75P-220 can be customized from our company, where 1.2. feet are connected in series with the load Connected to 36V grid, 3.4. pin connected to 220V grid.2. CON to COM must be positive. If the polarity is reversed, the output terminal will be 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 about 0-0.75V, it is a fully closed area, and the output of the module is reliably turned off; CON is about 0.75V-4.75V, which is an adjustable area, that is, as the control voltage increases, the conduction angle α is from 150 The temperature decreases linearly from ° to 0°, and the voltage on the AC load increases from tens of volts to the maximum value. When CON is around 4.75V-5V, it is a fully open area, 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 provided to the manual potentiometer, not used for other purposes. The resistance of the potentiometer selected is between 2-10KΩ.4. The speed regulation of single-phase AC asynchronous motors should usually use frequency converters. Only the soft characteristic loads such as fans and pump motors, or torque motors can be regulated by voltage regulation.5. Three single-phase voltage regulation modules cannot be used to regulate the three-phase load on a three-phase power grid (see Three-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 heating value of the entire module is calculated by the actual current amperage of the load multiplied by 1.5 watts/ampere. The radiator can be selected from E-40, F-70, F-100 and G series.8. Please refer to the single-phase AC solid-state relays for the precautions regarding the selection and protection of current levels .9. If the load has high requirements on the linearity of voltage regulation and voltage regulation, please increase the voltage negative feedback module .
