Introduction: Charging treasure is a must-have item for many people to carry around and recharge at any time. When charging the charging treasure, what should we pay attention to?
1, charging Po output voltage range.
The universal mobile power supply has a voltage output range of 5.3-0.5v. Although some devices have a USB interface, you also need to use PowerBag. However, you should pay attention to the input voltage range of your device. If your device requires an input voltage range that is not within the range of the mobile power supply, it is recommended that you do not use mobile power to power your device.
To ensure the life of your mobile power supply.
2, antihypertensive effect.
When using the 220V DC interface to charge the mobile power supply, it is required to charge the voltage down to 5V to charge the battery. The function of the PCBA board is tested here, and some protection boards will control the voltage and current of the charging. This guarantees security.
3, overcharge and over discharge.
Overcharge means that, for example, when the mobile power source is charged, it is 5V/1A. If it is too large, it will damage the core of the mobile power supply. The PCBA board will be strictly controlled. If it is within the fluctuation range, the PCBA is allowed to charge the mobile power. . If it exceeds, it will take the initiative to cut off electricity, unable to charge.
Overdischarge means that the cell is generally 3.7V. If it discharges to 3V when it is over-discharged, it will cause damage to the cell of the mobile power supply, reducing cycle times and performance.
Our company`s current transformers have high precision,wide range,small volume and good linearity that can be used to the field of electronic watt-hour meter, electric energy metering, electronic detection.
Performance
â—Power frequency insulation strength:The insulation between the primary winding and the secondary winding and the ground part of the CT can bear 4kV power frequency voltage for 1minute
â—Interturn insulation strength:The secondary open circuit, the primary winding through the rated current 1min, no inter-turn damage in the transformer
â—The deviation is better than the industry standards and national standards
