High voltage inverter power supply

1. Overview
The NHDA series sine wave inverter power supply adopts advanced sine wave pulse width modulation (SPWM) technology, with the main circuit using Siemens IGBT modules from Germany and the driving protection using Mitsubishi thick film circuits from Japan. It has the advantages of high reliability, comprehensive protection functions, low waveform distortion, and high power.
2. Main features
The NHDA series inverter power supply has an input DC voltage of 600VDC and an output AC 220VAC, with the following main characteristics:
(1) The main circuit adopts INTEL microprocessor from the United States, IGBT module from Siemens from Germany, and Mitsubishi movement from Japan for drive protection. The output part adopts isolation transformer, which is safe and reliable
(2) Using SPWM pulse width modulation technology, the output is a pure sine wave with stable frequency and low distortion
(3) Full bridge circuit structure, suitable for any load
(4) The DC input terminal adopts advanced backflow noise suppression technology, and the AC input terminal adopts multiple filtering to eliminate interference from the mains power grid, without interfering with other communication devices that share the DC screen
(5) Continuous switching of communication bypass
(6) It has a comprehensive power protection scheme and perfect self detection and protection functions. When there are low DC input voltage alarms, overload alarms, overheating alarms, and short circuits, the power supply will shut down the inverter output. After troubleshooting, manually reset the power supply to work normally; After the input undervoltage protection fault is eliminated, the output will automatically recover
(7) Compact circuit structure, high efficiency, and strong functionality
(8) Group screen installation, beautiful and elegant
