SANUPS E11A Series

Hybrid UPS Saves Energy and Achieves High Reliability
If commercial power were completely reliable, there would be no need for backup power. However, since occasional power interruptions and transients are inevitable, a UPS is essential to avoid device problems.
While the UPS must not waste power as long as commercial power is stable, it must be constantly available to provide power instantaneously in the event of a power interruption or transient. The SANUPS E11A is a UPS device that provides unprecedented power savings and high reliability.
Energy conservation

UPS:E11A Conversion efficiency has reached 95%.
This represents a 4% improvement over previous products (comparison performed at 1kVA).

The Hybrid type SANUPS E11A automatically selects the most efficient mode of operation for any given power condition.

High quality

Provides full sine wave output.

Output voltage accuracy is within ±2% (DOUBLE CONVERSION mode).

Self battery check feature

The SANUPS E11A automatically performs regular battery tests, and maintains the battery in peak condition for reliable operation during an actual power outage.

Easy power supply management

The UPS Management Software "SANUPS SOFTWARE STANDALONE" is included to enable you to manage power supply from a PC.
You can easily see the UPS status from a PC or server.

SANUPS E23A Series

Low energy, high quality, high reliability parallel processing type UPS
Communication equipment and computers are designed based on the assumption that uninterruptible power is supplied.

Input: AC200V, 3 phase 3 wire, Output: AC200V, 3 phase 3 wire
Output capacity: 20kVA(16kW), 50kVA(40kW, 100kVA(80kW), 200kVA(160kW)

Saves up to 13% on electricity rates.

・Achieved 97% of power conversion efficiency.
・Contributes to environmental protection.

Saves installation space.

・Achieved smaller size (area reduction of 40% compared to conventional model) and lighter weight (reduction of 50% compared to conventional model).
・When using a long-duration battery, since the optional charger is not necessary, the space required for installation can be reduced by 60%.

Supplies power for any system without voltage sag.

・Even during blackout, instantaneous blackout, or voltage dip, the complete sine wave power is supplied without interruption.
・Eliminates equipment malfunction caused by distortion of the waveform.
・Suppresses harmonic current.

Easy maintenance for cost reduction.

・UPS provides a routine automatic battery check.
・Since the capacitor supplies power when a short power interruption such as an instantaneous blackout, deterioration of the battery can be reduced.

Installation with a small investment.

・Maintenance bypass circuit is included as standard equipment.
・Eliminates the optional charger for long-duration backup.

The design considers the plant facility load.

・Since the overload capacity is high (800%: 0.5 seconds), rush current such as starting motor load can be endured.
