Power Quality Protection

If your facility depends on the reliable performance of your equipment to meet demands for productivity, quality, and cost. Power interruptions, no matter how minor, can not only stop production but can damage equipment, ruin inventory, and cause costly cleanup and delays.

Active Power’s products provide clean, reliable power, protecting operations against all types of disturbances. Our Uninterruptible Power Supply systems sample the electrical input 333 times every cycle or once every 50 micro-seconds and eliminates every transient using its static switch, line inductance, line capacitance, active filtering, power converters and flywheel energy storage.

The system senses voltage deviation from nominal and immediately corrects back to the prevailing nominal. Upon a complete loss of input power or a major deviation in input voltage or frequency, the UPS will disconnect from the utility source and flywheel energy will be used to support the load at nominal voltage until the backup diesel generator comes online.

The Basics

Flywheel systems store kinetic energy (energy of mass in motion) by constantly spinning a compact rotor in a low-friction environment.

A flywheel’s stored kinetic energy is proportional to the mass of its rotor, the square of its radius, and the square of its rotational speed (RPM).

Ek = K ⋅ mass ⋅ radius² ⋅ RPM²

All About Balance

Developing the optimal flywheel for a given application requires carefully balancing numerous factors. Increasing the rotational speed of the flywheel, for example, increases stored energy, but also increase the stress on the flywheel, requiring the use of stronger and more expensive material for the rotor. Similarly, a heavier or larger diameter wheel will increase energy storage, but perhaps with an unacceptable tradeoff in system size or transportation and installation costs.

Active Power’s CleanSource flywheels balance weight, size, speed, stress, and material strength to support a stored energy and cost profile optimized for our target markets in data center, health care, and industrial and manufacturing applications.

Keeping Your Power Pure and Uninterrupted

CLEANSOURCE® UPS Technology is based on Active Power’s Parallel Online Architecture which provides excellent isolation between input and output, while delivering IEC 62040-3, Class 1 voltage regulation and dynamically cancelling effects of non-linear load harmonics. This topology continuously provides online power protection to your facility, creating a clean sinusoidal output waveform and protecting critical operations against all nine IEEE power disturbances in a power dense, reliable, and energy efficient package.
