SANUPS N11D
Standby UPS SANUPS N11D designed to provide a stable power supply for motor-driven equipment. The product delivers up to 200% overload capability at rated output, ensuring reliable operation even for equipment subject to large power fluctuations. Combining high energy efficiency with flexible installation options, the UPS provides dependable backup power across a wide range of applications. The lineup includes three models―a lead-acid battery model, a lithium-ion battery model, and an EDLC(1) model.
Features
200% Overload Capability at Rated Capacity
During backup operation, the UPS delivers up to 200%(2) overload capability, supporting equipment with fluctuating loads, such as commercial elevators, robots, and motor-driven equipment.
High Efficiency, Energy Efficient, and Low Noise
With a power conversion efficiency of up to 98.6%,(3) the UPS reduces power consumption and CO2 emissions, contributing to the achievement of SDGs. The EDLC model can reuse regenerative power,(4) further enhancing energy efficiency. A low noise level of about 30 dB(5) allows installation in noise-sensitive environments. Using eco-friendly technologies, the product is certified as an Eco Product Plus.(6)
Abundant Lineup
The lineup includes the industry’s first(7) single-phase, 2-wire UPS offering a long-life, lightweight lithium-ion battery model, as well as an EDLC model optimized for voltage-dip compensation, in addition to a lead-acid battery model. Users can select the most suitable model based on their application and maintenance requirements. Its slim design makes it well suited for in-panel or wall-mounted installation. In addition, the UPS unit and battery can be installed separately,(8) greatly expanding installation flexibility.
