Mercury MDC3310S 10KVA/10KW 3-Phase Online UPS with USB/RS232/RS485 Interface

The Mercury MDC3310S is a high-efficiency 10KVA (10KW) true online double-conversion UPS engineered to provide stable, uninterrupted power for demanding industrial, commercial, and critical IT applications. Designed with a 3-phase input and 3-phase output (3/3 phase), it ensures balanced, regulated power distribution across mission-critical systems such as data centers, medical equipment, telecom infrastructure, and manufacturing plants. With a unity power factor (1.0), ±120VDC battery configuration, and advanced communication ports (USB, RS232, RS485), the MDC3310S delivers robust performance, extended runtime, and real-time management capabilities for environments where power reliability is non-negotiable.

Product Features

True Online Double-Conversion Technology with Unity Power Factor

The Mercury MDC3310S delivers continuous, isolated, and clean AC power by converting incoming AC to DC and then back to AC. This protects against all forms of power disturbances—spikes, sags, surges, and frequency variations—ensuring critical equipment operates without interruption. Its 1.0 power factor maximizes usable output, making the full 10KW power available for connected loads.

10KVA/10KW High-Capacity Output

Offering 10,000 VA (10,000 W) of power, this UPS is ideal for running enterprise-grade servers, switchgear, industrial control systems, and communication infrastructure. It handles high current demands and supports sustained uptime during outages or grid instability.

±120VDC Battery System with 20 x 9Ah/12V Batteries

Equipped with a robust battery bank (20 x 12V/9Ah SLA batteries), the MDC3310S provides significant backup time and ensures reliable performance during power loss. The ±120VDC architecture balances power delivery and allows for rapid recharging (6–8 hours to 90%), maintaining optimal uptime.

Flexible Input/Output/Battery Terminal Design

Integrated terminal blocks for input, output, and battery allow for easy and secure connection to complex power setups. This flexibility makes it suitable for scalable deployments in large facilities requiring centralized or distributed power architecture.

Advanced Monitoring with USB, RS232, and RS485 Interfaces

Users can monitor UPS status in real-time through USB for local access, RS232 for system integration, or RS485 for long-distance communication and connection to Building Management Systems (BMS). These ports support automated alerts, system shutdowns, and status reporting to ensure operational transparency and fast response to faults.
