Mercury MDC3310S Online UPS

The Mercury MDC3310S represents a robust three-phase UPS solution engineered for mission-critical enterprise applications. This high-capacity online UPS system delivers exceptional power protection for data centers, industrial equipment, and large-scale infrastructure installations.

Three-Phase Excellence

The MDC3310S utilizes true online double-conversion technology with three-phase input and output capabilities. This sophisticated system ensures perfect power quality by converting incoming AC power to DC, then back to clean AC power, eliminating all power disturbances. Furthermore, the unity power factor (1.0) design delivers the full 10KVA/10KW rating without derating.

Advanced Control System

A powerful DSP-based control system manages all critical operations, ensuring precise voltage regulation and frequency stability. Additionally, the system supports parallel operation of up to 4 units for expanded capacity or N+1 redundancy configurations. The system continuously optimizes performance through real-time monitoring and adjustment of operating parameters.

Comprehensive Monitoring Interface

A 7-inch color touchscreen display provides detailed system status, power flow analysis, and historical data logging. Moreover, multiple communication interfaces enable seamless integration with building management systems and remote monitoring solutions. The integrated SNMP capability allows network-based management and automated notifications.
