Product Introduction
  NHDA series high-frequency inverter power supplyIt is a specially designed and produced inverter power supply for the practical needs of communication systems and power systems, considering the size of space installation and the automation and networking requirements of inverter power management in the IT era, as well as the impact of noise on office or computer room work.
This inverter power supply adopts SPWM and CPU control technology, and the main circuit adopts imported power modules. It uses DC power from the DC screen or battery as input and outputs pure sine wave AC power after inversion. The output voltage and frequency are extremely stable and can work continuously for a long time, eliminating the adverse factors such as power interruption, voltage instability, noise interference, and lightning intrusion caused by direct use of mains power. At the same time, it overcomes the fatal defect of short power supply time of small UPS and ensures the continuous and reliable operation of electrical equipment.
Widely used in telecommunications, mobile, China Unicom, aerospace, financial management, office automation, industrial automation control, medical and health, military research and other fields.
  The inverter power supply can choose from three working modes (to be determined when ordering):
  Pure DC power supply type:Pure DC input, the inverter power supply shuts down and stops working after DC power failure.
  DC main supply type:DC and AC dual input, DC priority power supply, AC backup; Automatically switch to AC power supply after DC power failure.
  Exchange main supply type:DC and AC dual input, AC priority power supply, DC backup; Automatically switch to DC power supply after AC power outage.
Main Features

☆ Adopting intelligent CPU control technology and advanced PWM+SPWM pulse width modulation technology, the output is pure sine wave.

☆ LED+LCD status display, alarm signal display, and alarm recording function.
Flexible setting of AC main supply type and DC main supply type (changed through LCD panel or communication backend software).
Standard RS232 and RS485 communication interfaces, as well as fault dry contact signal interfaces.
☆ Protection against reverse connection, overvoltage, overload, short circuit, over temperature, temperature controlled fan, inverter faults, etc.
