MEGA POWER+ delivers one of the highest Calculations based on USA electricity cost
e ciency rates available. At an e ciency rate of MEGA Pay back time = 1.5 Years
96 %, MEGA POWER+ provides signi cant energy
and cooling savings.
MEGA POWER+ User-Friendly Controller
Each MEGA POWER+ features a unique and proprietary controller, which is the user's main interface with
the MEGA POWER+. The controller features a colored, touch-sensitive screen which enables the user to
navigate through the system screens by pressing various icons. Multilanguage functions allow simple
usage worldwide. The controller is not a failure point and UPS operation is not interrupted if the
controller is removed. Its interface o ers up-to-the-minute, intelligent monitoring of all UPS parameters,
including intelligent battery monitoring functionality, system voltage, temperature etc. Each system
element has its own control and history log. Built in SNMP/TCIP provides complete control over unit's
operation without installing software or using dedicated computers or control hardware.

5. MEGA POWER+ is a True Parallel Redundant UPS
True N+1 redundancy of 25 kW modules provides several critical advantages, including:
Flexible scalability: MEGA POWER+ ensures future growth in load increase with a wide power capacity
range: from 25 to 500 kVA / 500 kW. This scalability feature enables the user/designer unprecedented
exibility to correctly size the UPS for today, next month, next year (There is no need to supply spare UPS
capacity in advance; only what the user/designer currently needs.)
Minimal maintenance: MEGA POWER+ delivers very low MTTR (Mean Time To Repair), which results in the
fastest service with minimal costs.
Minimal Maintenance / Minimal Down Time
MEGA POWER+ o ers a truly modular con guration. Each 25 kVA / kW module is entirely self-contained
and ready for hot-swap and hot-plug – without requiring complex and expensive stocks of components,
subsystems, and spare parts. At any time, without shutting the entire unit down, any module can simply
be hot-swapped for replacement. This enables MEGA POWER+ to back up critical applications and data
centers that cannot a ord any downtime.
Unity Output Power factor
MEGA POWER+ performs unity output PF 500 kVA = 500 kW . The UPS is perfectly suitable for power
capacities loads , such as blade servers with ZERO reduction in active power.

leading solutions in this range.
The Mega Power+ is installed in many datacenters, hospitals, institutions, manufacturing
and industrial plants, telecom facilities and in many other applications.
The Highest Power Density / Smallest Footprint
Gamatronic's studies have shown that the issue of space requirements in today's world is critical.
MEGA POWER+ delivers extremely high power density = 5 kW / inch3. MEGA POWER + modules are
each 25 kVA / kW 3U and saves space in data centers, IT rooms and other critical sites.
Unique Design and Engineering
MEGA POWER+ o ers an “all-contained” original and proprietary design, where all connections and
cables are internal. Minimal access to the sides and rear of the unit is required.
MEGA POWER+ unique mechanical design provides a modular UPS solution to 500 kW (available bases:
125, 250 and 500 kW), setting a new standard for the market.
Mega Power+ Double Conversion True On-Line Battery (VFI)
According to IEC 62040-3
Complying with international standards such as AC Input DC link AC Output
the IEC-62040-3, and the highest classi cation Rectifier Inverter
VFI-SS-111, the Mega Power+ features a galvanic
battery connected between the recti er output Battery
