UPS Systems

UPS Types Explained

Standby UPS Systems

Power is fed through surge and noise suppression circuitry and on to your equipment. Meanwhile, a battery charger keeps an internal battery topped off and ready for use. During a blackout, brownout or overvoltage, an inverter converts battery power into a simulated sine wave output. When power returns, the UPS switches back to AC power and the battery is recharged. Sensing of a low voltage situation and switching to battery power happens so quickly that your equipment continues to operate flawlessly.

Ideal for: desktop computers, home networks, lab equipment, industrial control applications.

Line-Interactive UPS Systems

Power is fed through surge and noise suppression circuitry. Then built-in line conditioning circuitry regulates high or low voltages back to normal levels, and sends clean power on to your equipment, without using battery power. Meanwhile, a battery charger keeps an internal battery topped off and ready for use. During a blackout, an inverter switches on and converts battery power into a simulated sine wave output. When power returns, the inverter switches off and the battery is recharged. Because all switching happens within a few milliseconds, your equipment is unaffected.

Ideal for: audio/video equipment, office networks, small server racks.

On-Line UPS Systems

This is the highest level of battery backup protection available. Power is first broken down and then perfectly reconstructed by the inverter, which is "on-line" 100% of the time. There is absolutely no transfer switching time. This process completely eliminates incoming surge and line noise, adjusts high or low voltages, and produces perfect sine wave power.

Ideal for: server rooms, data centers, telecom equipment, sensitive, mission-critical equipment.
