Delta 20-120kVA User Manual

NH Plus series

Three phase 20-120kVA

Uninterruptible Power Supply

NH Plus belongs to “Delta High UPS” product series.
Based on the patented technology, It is designed for
high efficiency, high reliability and cost-effectiveness
requirement.

As fast changing in the data center and IT frame, you
need more flexibility for future power needs.
NH Plus combines scalability, hot-swappable and
manageability as your business grows.

Features and benefits

• Double conversion and IGBT topology.

• High input power factor (pf > 0.99) and low harmonic distortion (iTHD < 3%).

• Overall high efficiency (> 94%), savings in the operating cost.

• N+X parallel redundancy and expansion.

• Easy parallel link (up to 4 units) without extra hardware needed.

• Modular design provides easy and fast maintenance.

• Hot-swappable capability ensures continuous power during module replacement.

• Dual mains input increasing the availability by two separate power source.

• Smart fan speed control to reduce the noise.

• Built-in manual and static bypass switch for maintenance.

• Compatible with generator installation.
