SOROTEC UPS

Under normal operation, high frequency switching power supply equipment has little maintenance workload, mainly dustproof and regular dedusting. Especially in the area where the climate is dry, the dust in the air is more and the dust will be deposited in the machine. When the air is wet, the host control disorder will cause the main engine to be disturbed and the inaccurate alarm will occur. A large amount of dust also causes poor heat dissipation in the device. Generally, every quarter should be thoroughly cleaned. The second is to check whether the connectors and plugging parts are loose or unfastened during the dust removal. Because rectifier can not eliminate instantaneous pulse interference, there is still interference pulse after rectification. In addition to the function of storing DC power, the equivalent capacitance of the battery is directly proportional to the capacity of the storage battery. Therefore, maintenance of battery work is very important, although the battery ...

Pure sine wave inverter  power supply is specially designed for power plant, substation, communication industry, automation control equipment, solar energy, oil field, wind energy, new energy and so on. It is mainly applied to places where load equipment has high requirements to power quality. Such as power telecontrol, RTU, power line carrier, monitor, program-controlled switchboard, computer room, network, server and accident lighting. If the AC input is broken down, the DC screen or the external battery cabinet prepared by the power system and the telecommunications system will supply a long and uninterrupted power supply through the inverter for the load equipment. If the DC screen is broken down, the inverter overloads or failed, the system will automatically switch to the bypass power supply, which ensures the continuity of the system power supply. The use of pure sine wave inverter power supply to important load equipment in DC power station has the following advantages: ...

1.Check the power equipment regularly. Pay attention to the environment temperature and equipment operation status of the computer room, use the power supply monitoring system to monitor all kinds of operation parameters of the power equipment in real time, and find out the problems in time. 2.Power inspection content. Whether the configuration of the module is reasonable; Whether the charge current limit is correct or not; System AC voltage and current, DC floating charging voltage, load current, battery supplementary electric current, fan running status and lightning protection device status; Whether the running parameters of the monitoring module are correct or not; Whether the temperature compensation is normally used; Whether the module’s average flow is less than 5%; Battery insurance and connection bar temperature rise; Whether the battery is climbing acid, leaking or bulging; The ambient temperature of the machine room, etc. 3.The power supply monitoring system is used to ...

Low frequency UPS  and  high frequency UPS  are distinguished according to the operating frequency of the design circuit of UPS. Low frequency UPS is designed on the basis of traditional analog circuit, composed of thyristor (SCR) rectifier, IGBT inverter, bypass and power frequency step-up isolation transformer. Because of its rectifier and transformer working frequency are 50Hz, so called low frequency UPS. High frequency UPS is usually composed of IGBT high frequency rectifier, battery converter, inverter and bypass. The IGBT can control its opening and closing by adding control to the gate. The switching frequency of the IGBT rectifier is usually from thousands of Hz to tens of kHz, even up to a hundred kHz, far higher than the low frequency UPS, so it is called high frequency UPS.
