UPS Power Supply-related Power Terms Glossary (3)

Power factor: There are two different parameters of input power factor and output power factor for a device. The absolute value of power factor is between 0 and 1. It is between W (active power) and VA (apparent power). The number. The higher the input power factor, the higher the utility of the UPS to the power grid. The power factor of the energy-saving UPS is above 0.9. Considering from the output side, the higher the output power factor is, the stronger the UPS load capacity is, and the lower the output power factor is, the weaker the UPS load capacity is.

Power factor correction: means used to increase the input power factor of the electronic device. After the UPS is equipped with a power factor correction circuit, it can greatly increase its input power factor.

China socket: China's standard socket form, zero, FireWire V font arrangement, the ground in the V head.

American standard socket: The standard socket form of the United States, zero, FireWire is arranged in 11 fonts, the ground line is in the head of 11.

Common mode: refers to a way of the noise flow path. Any noise that comes from the HOT or NEUTRAL and returns through the ground is called common mode noise.

Silicon barrier diode: It is a diode designed with silicon (AILICON) as the main raw material. The difference between the silicon barrier diode and the general diode is: When the voltage exceeds its designed rated voltage. The polar body will produce an AVALANCHEEFFECT and turn on, so the silicon barrier diode is often used as a voltage regulator diode.

Fault current: refers to the flow of abnormal current in the line.

"Three remote": remote letter, telemetry, remote control. Refers to the remote monitoring of equipment.

Isolation: The power grid transmits power by fire line and neutral line, so external lightning strikes or * will damage the internal electronic components of the electrical appliances through the fire and neutral lines, so many UPS or electrical equipment are equipped with transformers at the output and input terminals. The equipment is electrically isolated from the grid to solve the above problems and reduce noise*.

High-frequency machine: The use of high-frequency switching technology to replace high-frequency switching components in rectifiers and inverters bulky power frequency transformer UPS commonly known as high-frequency machines, high-frequency machine small size and high efficiency.

Frequency machine: UPS, which uses power frequency transformers as the components of the rectifier and inverter, is commonly known as power frequency machine. The main features are the main power components are stable, reliable, overload capacity and strong impact resistance.

Management Information Base: A software module for supporting SNMP network equipment, which stores the status information of the network equipment for the network management system or user to query the equipment status.

Interactive: A working mode of the UPS. The basic structure consists of a bidirectional inverter, a battery, and a switch. When the grid fails, the inverter supplies power to the load. When the grid is normal, the inverter turns to charge the battery. The interactive UPS has a strong charging function, but the output has a switching time.

Backup type: A working mode of the UPS. The basic structure consists of an inverter, a battery pack, and a switch. When the grid is normal, the inverter stops outputting AC power, and the grid AC power is supplied to the load via the UPS. When the power grid fails (power failure, under voltage, overvoltage, etc.), the UPS goes to the inverter output mode by switching the switch. This conversion process has a switching time of 3-10ms.
