Modular 50 50 ~ 800kVA

Modular 50 series UPS is redundant, scalable, 3 – Phase UPS power protection system with on-line double-conversion and full DSP control technology. Its hot-swappable and flexible power module configuration makes the capacity scalable from 50 KVA up to 800 KVA, and the system capacity can be expanded to 2400 KVA by advanced “N+X” wireless parallel and redundancy technology. All internal modules (control module, power module and bypass module) are modularly designed and hot-swappable, assuring system compactness, reliability and easy maintenance.

Latest DSP digital control technology

High input power factor > 0.99, THDi < 3%, high efficiency 96%

“N+X” wireless parallel and redundancy technology: easily set up numbers of redundancy module on LCD panel, support 4 complete UPS in parallel, avoid single point failure and further strengthen the reliability

Consistently reliable protection for hardware and software, sophisticated detection inside the UPS, abundant event log for future check

Fault-tolerant design for fan system: 30% load can be taken when 2 fans fail and 50% load can be taken when 1 fan fails

High overload capability

105% ~ 110% for 60 minutes, 110% ~ 125% for 10 minutes, 125% ~ 150% for 1 minute

Intelligent hibernation design enables UPS to operate efficiently at low load rate

Independent bypass module design and redundant power supply components ensure higher reliability

Synchronous control function for 2N double bus system

7 inches LCD touch screen provides easy-to-use user interface

Easy maintenance with hot swappable operation for all modules

Hot-swappable modular design enables users to replace standard modules on-line, no need to turn off the UPS or switch to bypass for maintenance. This feature greatly decrease maintenance time, lower maintenance cost and difficulty

Load sharing technology

If any of the UPS modules fail, the load will be taken over by the rest of the modules without interruption. This increases the real time operation and power availability

Easy expandability and scalability

System capacity is scalable up to 600KVA constructed by each power module of 50KVA; each power module is equipped with charging function with maximum 10 A charging current. Users can periodically increase power modules according to load expansion plan to effectively control initial cost and reduce energy consumption per unit

Integrated power distribution

Mains input, bypass, maintenance and output breakers are integrated inside the UPS. It is easy for installation and save the cost of users

High power density

Modular 50 is featured with high power density of 50 KVA / 3U power module

Front accessible maintenance, top / bottom cable entry compatible ( 200KVA top cable entry )

Self-aging function make it easier to debug and test on site

Standard configuration with parallel port and BSC port

Ultra wide input voltage range and frequency

Modular 50 has a wide input voltage range (138 ~ 485Vac) and frequency range (40 ~ 70 Hz). It provides 50 Hz / 60Hz frequency auto-sense and two modes of frequency conversion: 50Hz input / 60Hz output and 60Hz input / 50Hz output

High output power factor 0.9

Output power factor 0.9 enables UPS to deliver more power and increase the load capacity

Flexible battery quantity settings

The battery quantity (30 ~ 46 pcs) can be configured flexibly. If there is battery failure, only removing the failed battery and resetting the battery quantity are required, no need to replace the whole group of battery

Cold start

Battery cold start is available. In the absence of mains power, battery cold start function allows users to start the UPS with the batteries to meet the emergency

Share battery pack in parallel operation, saving user’s battery cost

Soft-start technology improves generator matching up to 1:1.1

Standard Emergency Power Off (EPO)

Standard maintenance bypass switch

Advanced multi-platform communications: standard USB / RS485 / dry contacts and SNMP communication interfaces

Advanced intelligent battery management function: flexible battery configuration (30 / 32 / 34 / 36 / 38 / 40 / 42 / 44 / 46 pcs selectable), intelligent charging / discharging and float charging voltage temperature compensation
