Why do you need an UPS?

• Common power problems• Complete Power Failure – Total loss of utility power• Transient Voltage Sag/Spike – Short-term Under/Over-voltage• Brown-out – Long-term Under-voltage• Line-noise – Electro-magnetic interference• Frequency variation• Switching transient – Instantaneous under-voltage• Harmonic Distortion – Multiples of power frequency imposed on power

waveform (think ‘echo’)• “Utility power” for you and me means consistently clean, reliable and grounded

electricity from your regional electrical-utility company (Dominion Power, e.g..)• “Utility power” for a sailor, marine, or solider, usually means dirty, unreliable, and

often ungrounded electricity from a field-generator, fueled by diesel gasoline.

Power Solutions Portfolio

Who We AreWhere We Are

Standard Portfolio Features

• Power products function as both power conditioners and battery backup power• Double-conversion technology converts AC input power to a DC bus and then

generates a custom AC output waveform (defn. “online”)• Will accept wide input voltage range

before going to battery backup• Provides uninterrupted output

power regardless of input voltage

• Ungrounded delta input power is galvanically-isolated providing grounded wye output power

• Power Factor Corrected to near unity on input, thereby eliminating harmful load harmonics

NOVA appreciates the costs of environmental testing and work’s closely with our customers, often

observing tests at no cost to ensure successful acceptance.

Power Supply Limits – Battery Runtime

• Backup runtime directly related to battery capacity• Industry standard for as long as there have been UPS’s:

Valve Regulated Lead Acid / Sealed Lead Acid

• Disadvantages:• Poor energy density• Bulky size and weight

• Advantages• Ideal for long-term, stand-by use:

• Slower self-discharge rates • Float charge without voltage depression (ie. “memory”)

• Intrinsically safer than Lithium Ion

Type Energy/Weight Energy/Volume Self-discharge rate

VRLA 30-40 Wh/kg 60-75 Wh/L 3%/mo

NiCd 40-60 Wh/kg 50-150 Wh/L 10%/mo

NiMh 30-80 Wh/kg 140-300 Wh/L 30%/mo

Li Ion 150-200 Wh/kg 250-530 Wh/L 5-10%/mo
