1-10kVA High-Frequency Online UPS | DAXIN 11-H Series

Description

What Is the DAXIN 11-H Series 1-10kVA Online UPS?

The DAXIN 11-H Series is a high-frequency single-phase online UPS family available in 1kVA, 2kVA, 3kVA, 6kVA and 10kVA capacities. It is designed to provide continuous power protection for telecom, IT, healthcare, industrial control, financial and other critical electronic equipment.

Using true online double-conversion technology, the UPS continuously supplies connected loads through the inverter, providing 0ms mains-to-battery transfer during utility power interruptions.

The series supports wide input-voltage operation, input power factor correction, pure sine-wave output, ECO mode, generator compatibility and intelligent battery charging. Communication options include RS-232 and USB, with optional SNMP network management for remote UPS monitoring.

Standard and long-run configurations are available according to model and backup-time requirements. Optional features such as an isolation transformer and maintenance bypass can be reviewed according to the selected configuration and project requirements.

Why Use an Online Double-Conversion UPS?

An online double-conversion UPS continuously powers connected loads through the inverter rather than waiting for a utility failure before switching to battery operation.

This architecture provides 0ms mains-to-battery transfer and helps isolate critical equipment from certain utility-power disturbances. It is commonly selected for applications where power continuity and output quality are important, including telecom, IT, healthcare, industrial control and other critical infrastructure.

How to Select the Right 11-H Series UPS

Selecting the correct UPS capacity requires more than matching the nominal kVA rating. Consider the total active load in watts, equipment power factor, startup or surge requirements, required backup time, input-voltage conditions, communication requirements and future load expansion.

For long-runtime applications, battery capacity should be selected according to the actual connected load and required backup duration.

Provide DAXIN ENERGY with your equipment list, total load, input and output voltage, required backup time, communication requirements and installation conditions to determine the appropriate UPS and battery configuration.
