Product Features

True Online Double Conversion with DSP Control

Delivers pure sine wave output with zero transfer time, isolating critical loads from surges, spikes, brownouts, and other power disturbances. DSP (Digital Signal Processor) control ensures fast, accurate voltage regulation and improved system responsiveness.

3-Phase Input and Output

Ideal for large facilities and high-load applications, the three-phase architecture provides efficient, balanced power distribution and compatibility with industrial and enterprise-level equipment.

High Output Capacity with 0.9 Power Factor

Provides 36000W of usable power, maximizing real power delivery and supporting a wide range of modern, high-efficiency equipment.

N+X Parallel Redundancy (Supports up to 4 Units)

Supports up to 4 UPS units in parallel configuration for load sharing or full redundancy. N+X design provides automatic failover protection, maintaining continuity even during individual UPS failure.

Built-in and External Battery Support

Includes inbuilt batteries for standard backup time. External battery packs can be added to extend runtime based on critical load requirements.

Zero Output Transfer Time

Ensures seamless transition between mains and battery power with 0ms output transfer time—essential for sensitive systems and uptime-critical infrastructure.

Wide Input Voltage and Frequency Compatibility

Accepts input voltage from 208V to 478V AC and input frequency from 40Hz to 70Hz, ensuring stable performance even in challenging or unstable power conditions, including generator operation.

Low Input Harmonic Distortion with PFC

PFC (Power Factor Correction) technology keeps input current harmonic distortion under 3%, minimizing stress on upstream power infrastructure and reducing energy waste.

ECO Mode Operation

Offers energy-saving ECO mode during stable input power conditions, optimizing power usage without sacrificing protection.

Fully Digital Charging and Power Conversion

Utilizes advanced digital control over charging, rectifier, and inverter functions, ensuring accurate performance, higher efficiency, and better adaptability to varying loads.

Cold Start (DC Start) Capability

Allows the UPS to start from battery power when no utility power is available—critical for emergency startup or disaster recovery scenarios.

Intelligent Battery Charging Management

Monitors and manages battery charge cycles based on temperature and usage, helping extend battery life and prevent premature failure.

Emergency Power Off (EPO)

Includes EPO functionality for immediate shutdown of the UPS in emergency situations, meeting safety protocols and regulatory compliance.

7-Inch Touchscreen LCD Display

The large, full-color 7” touchscreen interface offers real-time status updates including input/output voltages, battery condition, alarms, and load information. Provides intuitive control and monitoring in a single panel.

Terminal-Based Input/Output Ports

Robust terminal ports allow secure connections for high-capacity systems and industrial installations requiring direct wiring.

Multiple Communication Interfaces

Standard communication includes USB, RS232, RS485, dry contact, and parallel port. Optional SNMP and relay cards support integration with building management systems, remote monitoring platforms, or automated alerts.
