Mission Critical Support Systems for Data Centers

Don’t Be Left in the Dark on Emergency Lighting

Are you in the dark when it comes to emergency lighting? With the Staco FirstLine® central lighting inverter, you can rest assured that your personnel will have the lighting they need in the event of a power failure.

That’s because the FirstLine® 924 automatically supports the connected lighting loads – providing power without interruption for a full 90 minutes.  When the utility power returns to normal, FirstLine® 924 automatically recharges the batteries to be ready for the next power disturbance.

This three-phase system will support three-phase or single phase loads.  Thanks to the true-online double-conversion technology, the FirstLine® 924 outputs a true sine wave with continuous no-break operation.  A compact, freestanding steel enclosure provides front and top service access for easy maintenance, along with an LCD front panel display for control and monitoring. All FirstLine® products are backed by an industry “on-site” warranty.

Additionally, the FirstLine® 924 protects the connected load from the AC primary supply, protecting it from damaging sags, swells, harmonics, noise, voltage imbalances and interruptions (blackouts). In addition to meeting life safety requirements, the FirstLine® 924 also can increase the life expectancy of the protected lighting and reduce long-term cost of ownership.

Single point operations allow simplified testing and recordkeeping.  Simplified service reduces overall cost of ownership.  Virtually all lighting types are supported, including:

• Incandescent
• Magnetic and electronic fluorescent ballasts
• High power factor compact fluorescent
• High Intensity Discharge (HID)
• High Pressure Sodium (HPS)
• Metal Halide (MH)

With a variety of user-friendly features and benefits, the FirstLine® 924 is ideal for use in many types of facilities including:

• Public buildings
• Theaters
• Schools
• Parking garages
• Housing complexes
• Manufacturing facilities
• Office buildings
• And more!

Is the Electrical Equipment in Your Plant Working in Harmony?

How Do You Know If You Have a Problem? Unlike a seized bearing or a fried motor, the effects of harmonics are often masked, because they don’t necessarily occur with the equipment causing the problem. Some common effects of harmonics problems are:

• Tripping of circuit breakers
• Controls, relays and other devices not functioning properly
• Overheating of bus bars, conductors and switchgear
• Breakdown of insulation which leads to shortened equipment life, and more.

What Is the Cause of the Problem? Technically – harmonics. But in layman’s terms, it’s really your electrical equipment that you use on a daily basis and can’t live without – like your computers. Yes, harmonics are created by such commonly used devices as transformers, computers, variable speed drives and UPS’s, and arcing devices like fluorescent and vapor lighting, arc welders and arc furnaces. Clearly, harmonic distortions are widespread – creating havoc in diverse businesses like small accounting firms to large manufacturing facilities.

What are Harmonics? Simply put – harmonics are voltages or currents that have multiplied within an electrical system. Commonplace linear loads continue to become more non-linear due to electronic and digital devices. These multiplied voltages or currents distort the shape of the traditional sine wave.

OK.  What Can I Do About It?
The main solutions to harmonic distortion are:

• StacoVAR® passive tuned filters – application designed
• StacoSine® Active Harmonic Filters – which clean the sine wave for all types of harmonic orders – from the 3rd to the 51st

Where both power factor correction and harmonics are a concern, StacoVAR fixed or switched capacitor banks can be provided with filter reactors.

Staco works with professionals across the country to help you identify which solution is best for you. Cleaning up your harmonic problems will have your facility singing a new tune. Who knows, maybe your productivity will finally hit that high note?
