GAMATRONIC 1UDC+ Power Systems DC 12V, 24V, 48V

Modularni ispravljači velike snage (AC/DC rectifiers) nominalnog napona po izboru (12V, 24V ili 48V) izraelskog proizvodjača Gamatronic. Ovi ispravljači se često koriste za napajanje telekomunikacione opreme kada se traži pouzdan rad i visoka efikasnost. Sistemi se mogu daljinski kontrolisati i nadgledati.

Karakteristike:

1UDC+ Power System
The Gamatronic 1U DC+ power system provides clean DC power to sensitive equipment while simultaneously charging the battery bank, and supplying backup power during mains failure.

The 1U DC+ contains a 19” 1 U subrack that can house up to 3 hot-plugged rectifiers, or 2 rectifiers + controller and an LVD device.

Max system capacity: Up to 13 subrack (38 rectifiers + controller), 1266 A with height of 13 U.

Basic shelf:

1U DC+ type I – includes a 19” 1U shelf (subrack) with up to 3 rectifiers.

Electronic Basic shelf:

1U DC +type II – includes a 19” 3U shelf with up to 2 rectifiers + SC
1UDC+ controller and an Electronic LVD device.

Main Features:

• 100A for each 1U shelf
• Intelligent power module, digitally controlled
• One to three hot-swap rectifiers in each shelf
• Active current sharing among rectifiers
• Universal input voltage
• A built-in dual 70 A Electronic Low Voltage Disconnect device (ELVD) for battery protection
• Option to connect 2 external LVD contactors up to 1600 A
• A high-performance, hot-swap system controller (SC 1UDC+) to measure, monitor and control voltages, current, power, battery, temperature, etc.
• USB (SC1U DC+) or TCP/IP+USB communication (SC 1UDC+ NET)
• Temperature compensation enhances battery life
• Battery current limit
• Up to two battery sets handled in one system
• Automatic and pre-programmed battery test (for each battery set)
• Automatic and pre-programmed equalized charging mode
• Comprehensive remote control and monitoring system using a dedicated graphical user interface (GeMSi, PSM-1UDC+)
• Breaking alert by modem (optional)
