EPS power supply is also known as EPS and fire emergency power supply. The full name is Emerge 13Cy Power Supply (emergency power supply), and the new national standard is GB17945-2010 "Fire Emergency Lighting and Equipping Instruction System".It is an emergency power supply used in important buildings for power guarantee and fire safety today.
The difference between EPS power supply and UPS working principle: UPS is uninterrupted power supply. The reserve energy rely on during work is some chemical energy generated inside the battery.After there is a certain problem with the power supply equipment, this power device can quickly provide some electricity to meet the needs of users.In fact, its working principle is not the only one, and it can be divided into three types.Here we will talk about the first one, that is, the backline of the backup. In this, the UPS power supply has a battery. Generally, it is powered by the municipal power.Switch for power supply.The structure of this power supply is generally simple, and the cost is not very high, but the voltage is unstable. If the requirements of some equipment are relatively high, this power supply cannot be used.The working principle of EPS is relatively similar to the working principle of the backup UPS. It also uses a battery to power the power, but when the conversion is converted, the switch is not converted, but the contactor is used.EPS consists of five parts, including chargers, inverters, battery packs, etc.The composition of this power supply is not very complicated, and the energy consumption is very low, and there is no noise at work.This power supply is generally used in some high -rise buildings.
EPS power repair
EPS power maintenance steps: 1. Check the EPS power supply, not only to check the voltage size with a multimeter, but also use an oscilloscope to check the voltage waveform.2. Check whether the crystal vibration is vibrated, you can use the oscilloscope to check the waveform of the crystal foot to view.3. Check whether the reset signal is normal, and whether the reset pulse is correctly sent to the reset of the CPU chip.4. The data bus, address bus, and control bus in the EPS emergency power supply can cause failure. You can judge whether there is any failure of a certain road on the ground resistance of the parallel bus to the ground resistance of the parallel bus, or observe the bus of various bus linesPolytable judgment.5. The EPS fire power interface chip is the most bad type of component. It can be determined whether it is damaged by replacement or dedicated instrument detection.
EPS power supply price
EPS power supply is generally between 200 and 300 yuan.
