The INEX inverter series is an integrated telecommunications power system, including inverter, static switch, LCD display controller, and interface modules. With a versatile “building block” design and N+1 redundant configuration, the INEX inverter system facilitates complex telecommunications and industrial power demands, and provides ultimate flexibility for your current and future power requirements.

N+1 parallel redundancy allows power capacity expandable up to 18KVA. INEX "all master" dynamic mechanism automatically shares and re-organizes critical loads to prevent interruption should any inverter module fail. The DSP-microprocessing controller gives real-time system status through a comprehensive LCD display, and allows programmable settings through the display panel. With a communication interface module installed, you can further control and monitor the system remotely.

  • Versatile modular design provides flexibility for different power applications
  • Expandable capacity up to 18KVA with N+1 redundancy configuration
  • "All master” dynamic mechanism eliminates single point failure to optimize reliability
  • Hot-swappable operation allows module addition or removal without powering down
  • High power density and high efficiency

Technische Daten


Electrical

The INEX inverter module provides pure sine wave AC power output for critical telecommunications equipment. Adopting N+1 redundancy design, the INEX inverter can operate up to 12 units in parallel. The INEX inverter module is specially designed with a compact size of maximized power density that can reach up to 5.57W/ inch3 for INEX 1000 and 8.36W/inch3 for INEX1500. A 1U height design allows the module to be installed onto a standard ETSI 300mm rack. The INEX module is a revolutionary telecom power solution in terms of maximum flexibility and reliability.

  • Pure sine wave
  • Hot-swap replacement in shelf
  • High efficiency >88%
  • DSP design for higher system reliability
  • Lower audible noise <55dBA
  • Smart fan speed control
  • N+1 redundancy system, load sharing difference < 5%
  • -48VDC Telecom system application
  • Wide operation temperature range, -20 to 70° C                                                                        
 
STS Module
The INEX STS (Static Transfer Switch) module increases
system reliability by automatic power transfer between
the inverter output and the AC mains. By setting up the
priority of operation mode, users can change the system
status of “on line mode” or “off line mode”. The on line
mode will keep the input power provided by the inverter
line and when the inverter fails, the line will switch to
AC utility line. In off line mode, the system power is
always connected to the AC utility line and will switch
to inverter power line when AC utility fails. The transfer
time is less than a quarter cycle which prevents the
power interruption. The reliable performance of INEX
STS module will provide the maximum protection to
the connected telecommunication equipment against
possible damage caused by the system power failure.
  • Universal input range
  • Back-feed protection
  • Redundant fan design
  • Operation Priority Setup of transfer by setting in Control Module
  • Fast transfer time, typically less than ¼ cycle
  • Wide operation temperature range, -20 to 70°C
  • Lower audible noise <55dBA
  • No-cross connect
  • Optional maintenance bypass switch function
   
Controller Module
The INEX controller module allows users to monitor the
system status in real time. Its superior design enables
users to manage the inverter and STS module status
including voltage, current, frequency, capacity and
temperature. With a user-friendly interface design, users
can easily manage the inverter and STS module settings
including voltage, frequency, redundancy (for inverter
module), and priority (STS module). The controller
module can also record the alarm history which can help
to understand the operating status while maintaining the
system or making further adjustments to improve system
performance.
  • CAN Bus protocol for module communication
  • Relay contact output for customized alarms
  • Hot swappable design
  • Real time clock embedded
  • Comprehensive LCD & LED for status display
  • Audible alarm function
   
INEX MBSDU

The INEX MBSDU maintenance bypass switch plus
AC distribution unit allows user to perform maintenance
service to system without shutdown. The integrsated
AC distribution manages output power connections
with NEMA or IEC outlets and bulk output terminals
with breaker protection.

Communication Interface

The communication interface includes several options
for wider applications which facilitates the remote
managing to the system. The standard ports include
relay contacts, RS-232, RS-485 and USB. Relay
contacts provide five programmable settings to display
customized information. RS-232 & USB ports provide
the serial connection to the PC for software monitoring.
RS-485 provides a long distance connection for direct
monitoring. The communication interface provides
powerful monitoring and management solutions to the
system manager.
