Introduction: UPS power supply is also called uninterrupted power supply. It is mainly used in computers, solenoid valves, pressure transmitters, etc. UPS power supply usually provides protection against high voltage or low voltage. The main factors affecting its service life include the product itself. The quality and storage usage.
UPS power is also called uninterrupted power supply. It is mainly used for computers, solenoid valves, pressure transmitters, etc. UPS power supply usually provides protection against high voltage or low voltage. According to the working principle, UPS is divided into three categories: online, backup, online interactive, the most commonly used is a backup.
The actual life of a large UPS battery pack is generally 5-8 years. The general manufacturer's warranty is 3 years and the battery price is very high. The general application is much higher than the cost of the generator, so many occasions are using the battery to play the role of transition buffer, 5kw equipment to ensure battery life can be 2 days, the price is estimated at 30w role. In addition UPS battery car battery, it is not easy to put the light, so that the battery life is damaged, and the UPS charging speed is relatively slow, with photoelectric full power takes about 72 hours.
According to the different quality of products, the service life is also different. The UPS power supply with high quality and good quality can be used for 10 years or more. In addition, depending on the environment in which the UPS power supply is stored, the environment must be dry, cannot be discharged frequently, and can be used for a longer period of time without being used for a long period of time.
KNLE2-63 Residual Current Circuit Breaker With Over Load Protection
KNLE2-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
