UMPS (Uninterrupted Motive Power Supply)

Specialized Drives Solutions

Beyond standard VFDs, Hitachi Hi-Rel offers highly innovative and specialized drive solutions engineered to enhance the reliability and performance of motor loads, particularly during power disturbances. These unique systems are designed to provide continuous operation and safeguard against critical process interruptions.

UMPS is a unique, energy-efficient solution providing uninterrupted power backup to 3-phase motor loads without requiring oversizing. This technically superior solution is ideal for critical motor applications where even a momentary power loss can be devastating.

Functionality: During normal power, UMPS provides online 3-phase power with double conversion, simultaneously charging its batteries. In the event of a power failure, the charged batteries seamlessly feed the motor through a controlled inverter, ensuring zero interruption to the load. Backup time is determined by load and battery capacity.

Key Features:
- Constant Motor Speed Control: Motor speed remains constant despite changes in input frequency or voltage variation.
- Rated Torque Delivery: Motor delivers rated torque even during lower input voltage conditions.
- Unity Power Factor: Offers unity power factor to the feeder, optimizing power usage.
- Microsecond Changeover: Ensures seamless switching of power sources within microseconds through an integrated Static switch.
- Multi-Inverter Compatibility: Possibility of connecting more than one inverter on a single battery bank for enhanced flexibility.
- Battery Protection: Automatically cuts off battery discharge after a pre-defined time if power is not resumed, preventing deep discharge and increasing battery life.
- Cold Start Capability: Optional feature for system start-up during complete blackouts.

Key Benefits:
- Uninterrupted Motor Operation: Ensures constant motor RPM and continuous operation until battery depletion, critical for maintaining process integrity.
- Superior Reliability: Offers a technically superior solution compared to conventional UPS for induction motor loads during total blackouts.
- Optimized Performance & Output Quality: Motor speed can be adjusted for maximum efficiency, throughput, and improved quality of output.
- Energy Savings: Variable motor speed control allows for significant energy conservation.
- Most Economical Solution: Provides uninterrupted power for motive loads more economically than conventional three-phase UPS systems in specific scenarios.
- Extended Battery Life: Protects batteries from deep discharge, prolonging their operational lifespan.

Key Applications:
- UMPS is ideal for any industrial application with critical 3-phase motor loads where continuous operation is paramount, and even momentary power loss can lead to significant production disruption or damage. This includes, but is not limited to:
- Process Industries: Where continuous mixing, pumping, or conveying is essential.
- Manufacturing: For critical production lines and automated processes.
- HVAC Systems: Ensuring constant airflow in sensitive environments.
- Pumping Stations: Maintaining water supply or wastewater treatment.
- Any application where consistent motor RPM is vital for product quality or process integrity.
