Generally speaking, the standard output power unit of a voltage stabilizer is KVA, and a 1KVA voltage stabilizer can carry a resistive load of about 800W. Refrigerators, air conditioners, and water pumps in household appliances are inductive loads, and inductive loads have 2-3 times the inrush current at the moment of starting.
What are the components of a stabilized power supply? A DC stabilizer is mainly composed of a power transformer, a rectifier circuit, a filter circuit and a stabilized circuit. The functions of each part are as follows.
The overload operation of the transformer means that the transformer exceeds the rated current value when it is running. The long-term severe overload operation of the transformer will not only reduce the efficiency of the transformer, but also increase the copper loss and cause equipment damage, which is not conducive to the economic and safe operation of the transformer.
1. Connect the input of the automatic power regulator to the power distribution board, and install a fuse that meets the power guarantee rate of the instrument on the user power distribution board to ensure the safety of electricity. 2. Connect the power supply of the electrical equipment to the output terminal of the fully automatic power supply voltage stabilizer.
High and low voltage protection-when the mains voltage is too high or too low, the UPS power built-in voltage regulator (AVR) will make appropriate adjustments to keep the mains voltage within the usable range. If the voltage is too low Or it is too high to exceed the usable range, UPS will convert battery DC power to AC power to continue power supply to protect user equipment.
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. I
