Product Description
The LCD Power Supply Pure Sine Wave Inverter is a new generation of intelligent MCU high frequency Power Supply inverter developed and designed for the requirements of communication Power systems, railway power systems, and other power systems to meet the high quality and High reliability requirements, and applicable to all the uninterrupted sine wave AC output systems that are sensitive to power interference and require reliable and clean.
Product Feature
1) The series is an intelligent dedicated inverter power supply, using intelligent microcomputer control technology, advanced control theory and mature and stable high frequency inverter mode, which can quickly respond to changes in the external environment and provide uninterrupted high quality AC output in real time.
2) Using advanced PWM+SPWM pulse width modulation technology, the output is a Pure Sine Wave with stable frequency and voltage stabilization, noise filtering, and low distortion.
3) Advanced DC-AC electrical isolation technology is different from other pseudo-isolation modes. It can truly achieve complete electrical isolation between DC and AC in all circuits, meets the isolation requirements of all application systems, and eliminates all possible interactive interference.
4) The unique non-linear control circuit can output pure sine wave under any load condition, with strong load capacity and good load compatibility.
5) With power-on self-check function, strong load capacity and good load compatibility. The built-in bypass switch improves the continuity and reliability of the inverter power supply.
6) With mains input 50Hz/60Hz adaptive function, you can track and memorize the mains input screen rate and inverter output the same frequency mode, so that the input frequency range of the inverter can reach 44Hz～66Hz, and the output 50Hz or 60Hz, a wide range Adapt to different power grids and equipment requirements.
7) With intelligent unattended function, after the output is turned off when the DC voltage is too high or too low, the mains power is down, etc., the DC voltage or mains returns to normal, and the power is automatically restored, especially suitable for unattended communication base stations.
8) The Pure Sine Wave Inverter has complete safety protection functions, DC input rush protection, and comprehensive protection measures such as overvoltage, overload, overtemperature, short circuit, and inverter failure.
9) The Pure Sine Wave Inverter adopts advanced anti-injection noise suppression technology and does not interfere with other communication equipment sharing the DC screen. The AC input terminal adopts multiple filters to eliminate the interference of the mains power grid and meet the needs of the application system for the main AC power supply.
10) There are two working modes of type A and type B in inverters, as below,
A) Grid Power AC main Supply: Type A power supply inverter is in the Grid Power AC output mode, when there is AC Grid Power, and automatically switches to the inverter output mode when the AC Grid Power input fails.
B) DC Power main Supply: Type B power supply inverter normally works in inverter output mode, and automatically switches to AC Grid Power bypass output mode when DC input fails.
11) The Pure Sine Wave Inverter has an LED/LCD status display and alarm signal display functions, and provides a complete and friendly man-machine interface.
12) The inverter has the function of direct power on of the mains, allowing users to bypass the mains output to supply power to the load when there is no DC input, allowing the DC to be cut off when the power is on, and automatically switching to the mains bypass, which does not affect the power supply of the load and facilitates the maintenance of the battery And replacement.
13) The inverters provide 5 groups of passive dry contacts, respectively used for DC input failure, AC input failure, inverter failure, load overload, bypass output alarm.
14) The inverters offer RS232 / RS485 communication interface to support real-time data communication function.
