The Gravitas X75-48S DC power system combines high-power-density hot-swap rectifier modules with a DC battery load distribution section and a monitor and control section.
DC standby system is intelligent for telecomms
Power systems bring together the intelligent control capabilities of the DSC1000 controller and the Gravitas ultracompact fully integrated DC standby system.
2+1 redundancy with up to 1300W output is possible.
The expanded system adds an additional "expander" shelf making the total height 2RU.
The expanded system holds up to six rectifier modules capable of providing up to 3900W.
It can be operated with up to 5+1 redundancy at up to 3250W.
Each rectifier is cooled by a fan at a speed which is a function of load and temperature.
The new X75 incorporates a high degree of intelligence offering remote control programmed via a PC web page over an Ethernet LAN.
The controller manages the system rectifiers, monitors the system parameters and has alarms for system failures.
These include rectifier problems, AC input alarm and overvoltage and overtemperature conditions.
AC input is a wide 85 to 264V and up to five circuit breaker protected DC outputs or up to 10 GMT fuse protected outputs are available with the base system.
A battery string breaker and a low-voltage battery disconnect are standard.
The expander shelf is supplied with the capability to link both shelves and comes with bus bar links to parallel the outputs.
The base and expander shelf can be operated as a battery backup, single feed power system. Request a free brochure from Unipower Europe ...
