Product Description

220V DC to 220V AC Pure Sine Wave Industrial Telecom Power Inverter Features Overview Banner
DC AC Converter Features
  • AC input startup available: The system can power on using the mains supply 220V input if there is no DC input.
  • Unattended operation: The system automatically switches between the DC input and AC input to provide continuous AC 220V to the load.
  • Comprehensive safety protection: Includes DC input polarity converse, over/low voltage, short-circuit, over-load, over-temperature, and inverting malfunction protections.
  • Converse current control: Designed not to disturb other communication devices operating in the same DC cabinet.
  • DC-dominated Mode: The inverter provides AC 220V to the load normally, and automatically switches to bypass AC 220V input if a DC input fault occurs.
  • AC-dominated Mode: The inverter remains on standby while the bypass provides AC 220V to the load. The load automatically switches to the inverter if a bypass AC 220V input fault occurs.
  • Maintenance bypass: Available for convenient battery replacement and system servicing.
DC AC Converter Application Scope
  • The pure sine wave inverter is specially designed for electricity utilities and communication systems.
  • It functions as a conversion device converting electricity from utility AC voltage or battery DC voltage into a continuous, purified AC power supply for computers and other critical electrical equipment.
  • Helps systems prepare for utility instability and power cuts, preventing supply distortions such as voltage drops, surges, spike voltages, and broadcast frequency interference.
  • This DC AC Converter is a new generation dual-input inverter solution designed to support high-reliability communication systems.
  • Equipped with 110V/220V/230V AC power supply inputs and 220V DC power supply support, bridging the gap between traditional UPS power supplies and standard pure sine wave inverter solutions.
  • Utilizes a novel design structure that helps supply clean, stable, and durable AC power for critical loads, matching the high reliability of the DC power system.
  • Designed specifically for telecom standards to ensure seamless conversion between AC and DC power supplies with virtually zero transfer delay.

Frequently Asked Questions
What is the advantage of using a Pure Sine Wave Inverter for telecom applications?

A pure sine wave inverter provides clean, stable, and harmonic-free AC output that matches or exceeds standard grid quality. This protects sensitive communication, data, and audio equipment from electrical noise, interference, and potential malfunctions.

How does the dual-input design function under normal and fault conditions?

The system supports two main modes: DC-dominated mode, which prioritizes the battery/DC system and switches to AC bypass dynamically on a fault; and AC-dominated mode, which defaults to the AC mains and switches to the inverter instantly upon a grid outage.

What is the switching delay between the Inverter and the Bypass?

The switching delay is exceptionally short (≤5 milliseconds). This ensures seamless system operation and keeps critical connected loads online without power interruption or reboot issues.

Does this inverter fit into a standard server rack?

Yes, it features a standard 19-inch rack-mount chassis (482mm width) with a compact 2U height (88mm), making it easy to integrate into standard telecom and IT racks.

What built-in protections are included for safe operation?

The inverter includes full automatic protection against DC input reverse polarity, over-voltage, low voltage, output short-circuits, overload, and high temperatures, ensuring reliable performance in harsh industrial environments.

How noisy is the inverter during full load operations?

The inverter is designed to operate very quietly, keeping noise levels under ≤40dB at a 1-meter distance, which is ideal for office, laboratory, and control room environments.
