80026-524-01-R 1500W 1PH AC/DC POWER SUPPLY

Ac/DC power supplies can be classified in a variety of ways, the following are some common categories:

Switching power supply:
Also known as switching power supply, switching converter, is a high-frequency power conversion device.
The input part is mostly AC power supply or DC power supply, and the output part is mostly the device that requires DC power supply.
Complete the conversion of voltage and current between the two.
Ac power supply:
A power supply device that generates and provides alternating current electrical energy.
The output voltage and current vary with time and vary from one extreme value to the opposite extreme value within the sine wave period.
It can be used to power a variety of electrical equipment, from household appliances to industrial equipment,

and can also be used for analog experiments, such as the measurement and analysis of AC signals.
Dc power supply:
A device that maintains a constant voltage and current in a circuit, such as a dry battery, a storage battery, a DC generator, etc.
Dc power supply has positive and negative two electrodes, when the two electrodes are connected with the circuit,

a constant potential difference can be maintained between the two ends of the circuit, thus forming a current from the positive to the negative in the external circuit.

Ac power supplies and DC power supplies each have their own unique advantages and disadvantages, the following is a detailed analysis of the two:

Advantages of AC power supply:

High transmission efficiency: Because AC can easily rise and fall voltage through transformer during

transmission, thereby reducing line loss and improving transmission efficiency.
Widely used: suitable for large-scale power systems, can meet the needs of various equipment for power supply.
Easy conversion: It is easy to convert electrical energy from one form of voltage or current to another through

transformers and other equipment to meet the needs of different equipment.
Disadvantages of AC power supply:

Poor stability: The output voltage and current change with time, and the stability is relatively poor. For devices

that require a stable power supply, it is usually necessary to add a voltage regulator.
Energy storage is difficult: Due to the characteristics of alternating current, energy storage is relatively difficult

and needs to be achieved by special equipment (such as capacitors, inductors, etc.).
Advantages of DC power supply:

Good stability: the output current and voltage are stable, small fluctuations, suitable for equipment with high

power stability requirements, such as communication equipment, computers, etc.
Easy to store energy: DC power can be stored by batteries and other devices, which is convenient to use in the absence of direct power.
The circuit is simple: in the direct current circuit, the voltage and current direction are always unchanged, so the

behavior of the capacitor and coil is always unchanged, and there is no current interruption or voltage conversion difficulty.
Disadvantages of DC power supply:

Low transmission efficiency: In the process of long-distance transmission, direct current is easy to produce a

large voltage drop due to resistance, resulting in low transmission efficiency.
High cost: The production cost and maintenance cost of DC power supply are high, because it requires more circuit

components and complex control circuits to achieve a stable output of current.
In summary, AC power supplies and DC power supplies each have their own application scenarios and advantages.

When selecting a power supply type, consider the actual requirements and device features.
