Can two single phase regulators be used in series?

Two single-phase regulators can be used in series. The following is for reference:

The solution commonly adopted by the domestic electrical test industry in the problem of 380V power supply input of contact voltage regulator is to connect the X end of a contact voltage regulator with two (or even) 220V coils, untie the A end of the two coils as the input end of 380V voltage, and untie the A end of the two coils as the adjustable output terminal of 0-430V voltage (so that when the two coils are connected in series, the original balance coil can be removed).

Two single-phase regulators can be used in series.

Method: Connect the X-end of a contact regulator with two (or even) 220V coils, unhook the A end of the two coils as the input of 380V voltage, and untie the A end of the two coils as the adjustable output of 0-430V voltage. In this way, when the two coils are connected in series, the original balance coil can be removed.

The pressure regulator is the fourteenth batch of energy-saving products in the electromechanical industry. It is widely used in voltage regulation, temperature control, speed regulation, dimming, power control and other places. The column-type electric voltage regulator has an output voltage waveform without distortion (the output voltage waveform distortion rate increment is <1%), and the column-type electric voltage regulator adopts an electric operating mechanism to reduce the operation labor intensity.

The output power can be adjusted from zero voltage, strong instantaneous overload capacity, low no-load current and no-load loss, high efficiency, low noise and long life. It is suitable for the use of various inductive, capacitive, and resistive loads. It is widely used in chemical industry, metallurgy, instrumentation, machinery manufacturing, light industry, public equipment, household appliances, etc.

Matters for use of contact regulators.

The wiring principle of the single-phase voltage regulator is like this, and the person stands in front of the voltage regulator and faces the terminal. The upper left is connected to the input live wire, the lower left is connected to the input neutral line, the upper right terminal is the output live wire, and the lower right terminal is the output neutral line. This explanation hopes to help you.

There are two binding posts on the left that connect to the incoming wire or connect to the bottom zero, and there are two binding posts on the right that connect the line to the fire and connect to the bottom zero. It turns out that the zero line is connected to the head and tail of the common incoming line, and the outgoing line is connected to the middle tap and the common head, which is the principle of autocoupling.

Thyristor voltage regulators are also known as "thyristor power regulators", "thyristor power regulators" or simply "power regulators". A thyristor, also known as a thyristor (SCR), is a four-layer, three-terminal semiconductor device that is connected between the power supply and the load, and with the corresponding trigger control circuit board, the voltage, current and power applied to the load can be adjusted.

Generally speaking, A is the input of the live line of the voltage regulator, X is the input of the neutral line of the voltage regulator, A is the output of the live wire of the voltage regulator, and X is the output of the neutral line of the voltage regulator. There are pressure regulators that cut corners, and X and X are a terminal terminator.

1. Single-phase pressure regulator in the cavity, input AC 220, output range: 0-250V, capacity: 500VA.

2. Wiring: phase wire at the input end.

Connect the A terminal. Neutral wire connection X terminal;

The output terminal is connected to terminal A on phase wire, and the neutral wire is connected to terminal X.

3. Precautions, before turning on and off the power supply, Yusen needs to rotate the adjustment knob counterclockwise to the minimum position, so as to avoid damage to the voltage regulator and the connected equipment caused by the inductor potential.

4. Rotate clockwise, and the output voltage will be increased by adding a virtual shirt; The counterclockwise rotation output decreases.

4. The voltage regulator is powered off.

It is possible to connect the AC regulators in series, but there are a few points that must be noted:

1. The output voltage of the pre-stage voltage regulator shall not exceed the rated input voltage of the rear stage voltage regulator, otherwise danger may occur.

2. No matter which voltage point is adjusted, the output current of each voltage regulator shall not exceed their respective rated output current.
