48vdc to 110vac inverter for Railway Signal & Telecom

Views: 0 Author: Site Editor Publish Time: 2026-01-19 Origin: Site

NASN 48VDC to 110VAC pure sine wave inverter, designed for railway signaling and telecommunications, converts 40-60VDC telecom battery power into stable 110VAC/60Hz. The pure sine wave inverter feature rack-mountable designs, high efficiency (≥85%), and robust protection (overload, short circuit), including automatic AC bypass for high reliability.

Key Features for Railway/Telecom Applications

Voltage Range: Designed for 48VDC nominal inputs, with operating ranges generally spanning 40VDC to 60VDC, suitable for battery-backed systems.
Output Stability: Pure Sine Wave (PSW) output ensures compatibility with sensitive electronic equipment, signaling systems, and data equipment.
Reliability: Built in automatic transfer switches (ATS) from inverter to grid/generator power, critical for unattended sites.
Design & Standards: Rack-mount configurations (1U, 2U, or 4U) with built-in LCD monitoring for real-time voltage, current, and status display.
Remote Power Management optional via RS-232 port,SNMP optional.
