Key Features:

True Online Double Conversion: The UPS continuously converts incoming AC power to DC and then back to AC, providing high-quality power without interruptions.
Microprocessor Control: Utilizes sophisticated microprocessor-based technology for precise regulation and increased reliability.
Input Power Factor Correction: Ensures efficient power usage and reduces energy losses by correcting the power factor of the incoming AC supply.
Output Power Factor: Typically has an output power factor of around 0.8, allowing it to support a wider range of connected devices.
Wide Input Voltage Range: Capable of accepting a broad range of input voltages (e.g., 110V-300V), ensuring stable operation even in fluctuating grid conditions.
High Efficiency: Operates in a high-efficiency mode (often a "Green" or ECO mode), reducing energy consumption and heat generation.
Generator Compatibility: Designed to work seamlessly with generator power sources, making it ideal for backup power systems.
Monitoring and Control: Many models include an optional SNMP (Simple Network Management Protocol) card that enables remote monitoring and management, along with USB and RS232 interfaces for local management.
Emergency Power Off (EPO): Safety feature that allows for immediate shutdown of the UPS in case of emergencies.
Battery Management: Advanced smart battery charging technology increases battery life and performance through regulated charging cycles.
Built-in Isolation Transformer: Some models come with an optional built-in isolation transformer, providing electrical isolation for enhanced safety and protection.
Maintenance Bypass Switch (Optional): Some units offer an optional maintenance bypass switch that allows for servicing the UPS without interrupting power to connected equipment.
LCD Display: Typically equipped with an LCD display that shows real-time information about battery status, load levels, and operational parameters.Overload and Short Circuit Protection: Built-in protections prevent overloads and short circuits, ensuring the safety of both the UPS and connected devices.
