Product Description

Product Description

Product Overview

The LDT - M900 series long - distance intelligent power supply upper computer (host) is a high - efficiency, high - performance double - conversion product with a modular design. It is mainly suitable for scenarios in electromechanical projects such as high - speed railways where the power supply mode is strip - shaped, the power supply distance is long, and the load is relatively small and scattered. It is generally set in management centers, toll stations, service areas, or maintenance work zones. It mainly solves the power supply problem for equipment with a transmission distance within 30km and a cumulative capacity of less than 50KVA.

The system adopts advanced pulse width modulation IGBT inverter technology and an internal AC - DC - AC circuit design structure. Equipped with a professional isolation transformer, it completely eliminates power grid interference. The output waveform is pure, with voltage stabilization and frequency stabilization functions. Meanwhile, it has high precision, light weight, small size, a wide input frequency range, and high output voltage frequency stability. The output uses an isolated power module, ensuring safety and reliability.
