| The difference between Santak UPS power supply and DC panel |
| Time：2018-09-01 Source： Views：2690 |
If the DC screen alone, it is only a distribution panel, like AC distribution, it is AC input and DC output, the middle is some protective components, circuit breakers or fuses, each protective component has a monitoring line connected to the monitoring unit for monitoring, DC input in general there will be a backup battery, AC. When the power goes out, it can support for a period of time. If it is the whole set of switching power supply, it will include AC screen rectifier screen DC screen.
The differences between DC screen and UPS are as follows: __1, DC screen and UPS have different application occasions; _2, DC screen mainly provides operating power or control power for switchgear, integrated protection devices; UPS mainly provides backup power for computer room, computer and so on. The principle of UPS is that the AC is converted into DC and the load is supplied by the DC screen; the principle of UPS is that the AC is converted into DC first, and then through the inverter unit, the DC is converted into AC to supply the load. The two of them are powered by their battery pack when the power failure occurs.
4. The function and structure of DC screen and USP are different: DC screen is the abbreviation of DC power supply operating system. Common name is intelligent maintenance-free DC power supply screen, referred to as DC screen, the general model for GZDW, and DC screen is used to supply this DC power. The power supply used in power plants and substations is DC power supply. It provides power supply for controlling load, power load and illumination load of DC accident. It is the basis of control and protection of modern power system. DC screen consists of AC and distribution unit, charging module unit, buck silicon chain unit, DC feeding unit, distribution monitoring unit, monitoring module unit and insulation monitoring unit. Mainly used in power system small and medium-sized power plants, hydropower stations, all kinds of substations, and other use of DC equipment users (such as petrochemical, mining, railway, etc.), suitable for switching on and off and secondary circuit instruments, meters, relay protection and fault lighting occasions. __USP is the uninterruptible power supply, which connects the storage battery (mostly lead-acid maintenance-free battery) with the host computer, and converts the direct current into the market power through the host inverter and other modular circuits. Mainly used for a single computer, computer network systems or other power electronic equipment such as solenoid valves, pressure transmitters to provide a stable, uninterrupted power supply. When the power input is normal, UPS will supply the load after voltage stabilization, at this time UPS is an AC voltage stabilizer, and it also charges the battery in the machine; when the power supply is interrupted (accident power failure), UPS will immediately supply the DC power of the battery to the load through the method of inversion zero-switching conversion to continue to supply 220V to the load. Alternating current keeps the load working properly and protects the load software and hardware from being damaged; UPS devices usually provide protection against high or low voltages.
