1. Product Introduction:
The NHDS series DC remote power supply station terminal machine is an intelligent station terminal boosting system developed by our company based on years of power development and operation experience to meet the remote power supply needs of communication products. This system is the core of the remote power supply system, capable of isolating and boosting the 220VAC/380VVAC local power supply to 0-1000VDC (AC/DC). It adopts advanced pulse width modulation (PWM) IGBT inverter technology, and adopts an AC-DC-AC circuit design structure internally. It is also equipped with a dedicated high-frequency isolation transformer to completely eliminate power grid interference. The output waveform is pure, with stable voltage and current functions, high accuracy, intelligence, high reliability, high efficiency, high power density, low electromagnetic interference and other characteristics.
2. Product features:
--Adopting PWM power electronic conversion regulation technology;
--Protection functions such as input and output overvoltage, overheating, short circuit, power overlap, and strong current intrusion;
--Modular hot swappable structure, high power density, and support for N+M redundant parallel design;
--Both software and hardware adopt anti-interference design to improve anti-interference ability;
--Provide equipment self diagnostic function to facilitate equipment maintenance;
--Automatic power on function, no need to restart when receiving a call;
--Input/output configuration with lightning protection and surge protection;
--DC output suspension safety design ensures the safety of remote power supply effectively;
--Equipped with intelligent monitoring and management functions, fully Chinese LCD display, and user-friendly human-computer interaction interface;
--Equipped with remote control and communication interfaces for easy connection with computer control systems;
