Embedding microprocessor chip technology and thyristor controllable technology in the design of intelligent AC voltage regulators (or automatic voltage regulators (AVRs)) can generate high-quality and stable power supply in the presence of significant and continuous deviations in the mains voltage.

The uninterruptible power supply system can cause power outages in equipment such as program-controlled switches, data communication processing systems, computers, communication base stations, and security monitoring systems during operation.

The dry-type transformer overload capacity is related to the ambient temperature, the load condition before overload, the insulation heat dissipation time constant of the transformer, etc., but the empty capacity of the dry-type transformer also determines the overload capacity.

CNKHZ (UPS) uninterruptible power supply, with its high efficiency, high reliability and intelligent design, ensures stable operation of equipment, filters out grid noise, and quickly switches to battery power supply. It is widely used in key industries such as IT, communications, and medical care.

In the classification of uninterruptible power supplies, Power frequency Uninterruptible battery primary and High-Frequency Uninterruptible Power Supplies are two common types, Which have obvious differences in technical characteristics, application scenarios, and performance.

Transformers are electrical equipment and need to be maintained after working for a certain period of time. However, for some special sites, the transformer cannot be stopped, so the maintenance items to be paid attention to during the operation of the transformer are more important.

For dry-type transformers, the allowable temperature during operation is generally related to the heat resistance level of their insulation materials. The H-grade insulation paint has a temperature rise of 125K and a maximum allowable temperature of 180 ℃.

During the installation of low-voltage power distribution cabinets, it is mainly divided into top line entry mode and bottom line entry mode. During installation, we connect the power supply to the input terminal of the circuit breaker of the low-voltage power distribution cabinet, and its output end is based on actual needs. Connect to the output terminals of the circuit breaker of the power distribution cabinet.

The service life of the transformer is the longest among the entire components, and the failure rate is extremely low only when it is not destroyed by humans and when the load fails. However, excessive temperature rise is the cause of transformer failure.

SMD inductors belong to a large category under inductance, which can be divided into multiple sub-categories, such as: SMD shielded inductors, SMD unshielded inductors, SMD high current inductors, etc. The big difference between high-current chip inductors and ordinary inductors is that they can accept larger currents.

A transformer is an electrical device that uses the principle of electromagnetic induction to convert an AC voltage into another AC voltage without changing the frequency. The converted output voltage fluctuates with fluctuations in the input voltage.

When choosing a transformer, the sales staff will ask how big a transformer is needed, and this size represents two values, one is the power and the other is the capacity. The capacity of the transformer is related to whether the purchased transformer can be used.
