Product Overview
The document is a product catalog for static converters used in AC voltage emergency supply systems. It outlines the principles of operation, technical specifications, and features of these devices, which are designed to provide reliable power supply in both normal and emergency conditions.

Principles of Operation
There are two types of users: those always fed (SA) and those fed only in emergency conditions (SE). The converters can operate in two modes:

• UPS Mode: SA users are continuously fed by the inverter, while in power failure conditions, both SA and SE users are supplied.
• Emergency Supply (Eco-mode): Users are fed directly by the main supply under normal conditions, and by the inverter during power failures.

External contacts can control the feed of SE users.

Technical Specifications

• Input: Nominal voltage of 230V single-phase or 400V 3-phase, with a frequency of 50Hz ±2% and a power factor > 0.95.
• Output: Nominal voltage of 230Vac ±1% or 400Vac ±1%, with a frequency of 50Hz ±1% and a sinusoidal waveform.
• Other Features: Includes a backup time of 60 minutes, lead-sealed batteries, and an inverter efficiency of 92% at nominal load.

Additional Features

• LCD meters and LED signaling for various parameters such as input/output voltage, frequency, and battery status.
• Interfaces include RS232 and dry contacts, with an optional SNMP interface.
• Commands for online working, energy saving, battery testing, and emergency power off (EPO).

General Information
The converters are designed with advanced components for high reliability and easy maintenance. They are suitable for emergency lighting and privileged users, ensuring protection from main disturbances. ELIT Srl reserves the right to modify products without notice.
