(200 VAC / 208 VAC / 220 VAC)

NEDM30 Series – Modular Online UPS

Nova Electric’s NEDM-Series Modular Online UPS provides the compact footprint of less than 4.5 m2 with maximum capacity of 900 kVA in parallel, designed to protect any critical load for medium and larger data center achieving maximum availability. The DM series feature the latest 3 level technology and PFC input control, which guarantees high efficiency of 94% and ultra-reliability, making it an excellent choice for medium and larger facilities.

 FRIENDLY USER INTERFACE

Each power module has an independent LCD which gives users’ direct overview pf status data and alarms in real time.

 FRIENDLY INTERFACE

The LCD display accurately communicates the comprehensive status of the UPS to the user. UPS parameters can be modified easily through the 10.4” LCD display.

 COMPREHENSIVE MONITORING MANAGEMENT

In each power module, information of critical components is monitored and displayed in real time, giving customers a view of inner
status of the system and providing reminder information for maintenance.
• Maintenance reminder, running time of capacitors and fans displayed and recorded
• Comprehensive temperature monitoring for thermal abnormal detection
• Intelligent battery charger for long battery life

 CRITICAL WAVEFORM RECORDING

UPS can record and save the data of the main parameters automatically when faults happen for further analysis.
• Can record data information and present as waveform for further analysis
• Can easily spot the causes of the failures, avoid future similar faults

 SMART SLEEP

Smart Sleep function can intelligently make some power modules go to sleep when load is relatively low, improving the efficiency of the remaining power modules and saving customers on power and cooling costs.
• Improving efficiency, reducing power and cooling costs
• Easy setting with just two steps. Customers can select sleep mode and rotation period
• Power modules working in rotation, prolong the life time

 SELF-AGING

Self-aging is an advanced function applied in all three phase UPS, Self-aging function can test UPS under different load situation
without real load, saving more than 90% of energy.
• Simulate different load conditions without connecting to any real load, saving 90% of energy
• On site setting supported, easy for factory testing

 PROGRAMMABLE DRY CONTACTS

Programmable dry contacts are available in all NEDM, NERML and NC11 series UPS. Customers can easily expand or modify the
definition of each port.
• Abundant options with three inputs and four outputs, all programmable
• Easy setting, just pull the drop-down menu and set
• Compatible with all the NEDM, NERML and NC11 series
