Toshiba G8000MM - Manual (Page 2)

State-of-the-Art Modular Design Provides Maximum Flexibility
The Toshiba G8000MM Uninterruptible Power System
utilizes state-of-the-art design and construction to
deliver industry-leading reliability and the flexibility to
meet today’s critical power demands.
• Technologically Advanced Control of Fast-Switching IGBTs Delivers
94% Efficiency
• Combination Diode Bridge and Broad Range Harmonic Input Filter
Delivers Low Input Total Harmonic Distortion (THD)
• Low THD Reduces Heat Loss in Associated Feed Equipment and
Increases Component Life
• Self-Contained Modular Design Allows Low Cost Future Expansion
• Combine up to Eight Modules for Increased Capacity or
Redundancy
• Highly Efficient Hybrid Static-Transfer Switch Built Into Each Module
• Parallel Output Tie-Cabinet Requires Minimal Intelligence Circuitry
Reducing Purchase Cost
• Superior Output Voltage Regulation Provides Non-Distorted Output
Power when Subjected to Severe Step Loads with Minimal
Utilization of Batteries
• Generator-Friendly Interface Allows 1.1 kW Generator Capacity to 1.0 KVA UPS Load
• Advanced Battery-Control Ingenuity Produces Low DC Ripple -- Extending Battery and Capacitor Life
• Fail-Safe Design Incorporates Robust, Conservatively Engineered Devices to Reduce Failures and Ensure
Reliability
High Efficiency Design
• G8000MM Efficiency Greater than 90% at Loads 25% and Larger
• Higher Efficiency Means Lower Power Losses Equating to Lower
Utility Cost
• Lower Air-Conditioning Requirements
• Reduced Total Cost of Operation and Ownership
• High Efficiency Provides Rapid Return of Investment
Hybrid Static Transfer Switch
• Each UPS Module Equipped with Hybrid Static-Transfer Bypass
Switch
• In-Line Configuration and Make-Before-Break Switch Design
Ensure a Seamless Transfer of Power to Critical Load
• Redundant Switches Reduce Single Point of Failure in One Static
Switch Cabinet Design
• Hybrid SCR/Contactor Design Improves Static-Switch Efficiency
to Nearly 100%
• Lowers Utility Cost and Overall Cost of Operation
