What Is an AC Power Plug?

AC power is a modern word and is a proper noun. It refers to the plug and socket refers to the device used to connect the AC power provided by the city power supply to the household appliances and portable small devices.

Household AC power plugs and sockets refer to devices that are used to connect AC power provided by the city power supply to power household appliances and portable small devices.
The power plug has a male connector protruding in the shape of a rod or a copper plate, and is a female connector type that is physically inserted into a slot or a recess.

The three-phase voltage regulator is actually to connect the three voltage stabilizing units with "Y" connection method. Then use the control circuit board and the motor drive system to control the voltage transformer to achieve the function of stabilizing the output voltage. The sliding arms of the voltage transformers are all driven by one motor. The voltage regulation method is a unified regulator. If the sliding arms of three voltage transformers are independently adjusted by three motors, the voltage regulator is a three-phase divided regulator. Device. They work in exactly the same way as single-phase regulators.

(1) The uninterruptible power supply shall be powered by two AC power sources.

(2) The AC input of the uninterruptible power supply device shall meet the requirements. The continuous fluctuation range of the AC input voltage does not exceed 10%, and the harmonic content does not exceed the relevant regulations.

(3) The AC power of the uninterruptible power supply device should not be powered by the same transformer and bus as other impact loads.

(4) The input and output circuits of the uninterruptible power supply device should use cables. ^[1]

The AC stabilized power supply is an important part of power supply technology. Its input is single-phase or three-phase AC power, and the output is still AC (single-phase or three-phase). According to the working principle of AC stabilized power supply, it can be divided into four categories:

1. Parameter adjustment (resonance) type (CWY series and JJW, JSW series) sinusoidal energy distributor;

2. Self-coupling (transformation ratio) adjustment type (ZTY series) Japan Matsunaga technology;

3. High power compensation type (SBW series);

4. Switch type (high-frequency switching power supply technology);

In order to deeply understand the performance characteristics of AC stabilized power supply, here is a brief description of the main technical indicators of AC stabilized power supply. Steady-state performance indicators:

1. Source voltage range: The input voltage range. The AC stabilized power supply does not stabilize the output voltage under any AC voltage input, but has an adaptation range.

2. Source voltage effect (also known as voltage adjustment rate): It is defined as "the effect that the output quantity changes only because of the change in input voltage. Expressed by:
Su = (Umax / Uon) * 100% where: Umaxthe maximum value (V) of the output voltage change when the input voltage is adjusted up or down.
