21V1.5A DC Regulated Battery Charger Supplier

DC regulated power supply generally has multiple outputs: for example, it provides a fixed output of 5V and 2A; Provide two channels (A and b) with adjustable output of 0 ~ 24V and 0 ~ 1a. The adjustable output generally has two working modes: voltage stabilization and current stabilization.

Basic functions of DC regulated power supply

Precautions for use

1. According to the required voltage, first adjust the "coarse adjustment" knob, and then gradually adjust the "fine adjustment" knob, so as to achieve correct cooperation. For example, when 12V voltage needs to be output, set the "coarse adjustment" knob to 15V, and then adjust the "fine adjustment" knob to 12V, while the "coarse adjustment" knob should not be set to 10V. Otherwise, the maximum output voltage is less than 12V.

2. After the voltage is adjusted to the required load.

3. During use, if it is necessary to change the "coarse adjustment" gear, disconnect the load first, and then connect the load after the output voltage is adjusted to the required value.

4. During use, when the protection is caused by load short circuit or overload, first disconnect the load, then press the "reset" button, or turn on the power again, the voltage can return to normal operation, and then connect the load after troubleshooting.

5. When various power supplies with different rated currents are used in series, the output current is the rated value of the least rated one.

6. Each power supply has a meter, which indicates the output current or output voltage of this circuit respectively in different states of a / v. It is usually placed in the voltage indication state.

7. Each circuit has two output terminals, red and black. The red terminal represents "+" and the black terminal represents "-". A black terminal connected to the "Earth" symbol in the middle of the panel indicates that the terminal is connected to the chassis and has no electrical connection with each circuit of output. It is only used as a safety wire. It is often taken for granted that the "Earth" symbol indicates grounding, and "+" "-" indicates that the positive and negative power outputs are used to supply power to the dual power operational amplifier.

8. The two voltages can be used in series. Parallel connection is absolutely not allowed. The power supply is a kind of supply instrument, so it is not allowed to short circuit the output terminal for a long time.
