The Unipower Guardian Access 2U 100 amp dc power system is a 2U high 19″ rack-mounted, integrated dc power system providing an output of -48Vdc. These systems can accommodate up to 3 Guardian family high efficiency hot-swap rectifiers.

The Guardian access 2U system provides a total load current of 100A / 5.4kW is available with battery charge current up to 65A in addition. The rectifiers are internally fan cooled with speed control which is a function of load and temperature, keeping acoustic noise to a minimum.

The dc output circuits can provide up to 6 loads which utilize circuit breakers rated from 4A to 150A; 2 additional 80A; 100A or 125A breakers provide battery protection. A programmable 125A low voltage battery disconnect (LVD) is standard while a partial load disconnect (PLD), also rated at 125A and programmable, can provide non-critical load shedding when operating on batteries.

The ACC extended remote access controller monitors system parameters, controls rectifier output, and provides alarms for system failures.The Controller Module is also pluggable for easy field replacement in case of failure. There are 2 LED alarm indicators which indicate failures, (red) Alarm and (yellow) Message. A third green LED indicates the controller is working properly. As standard four form-C relay outputs provide the alarms for remote use. An additional 6 can be included as an option. Two digital inputs and outputs are also provided as well as a microSD card slot that accepts an up to 4GB card which is sufficient for more than 20 years data logging.

The system can be programmed by means of a remote PC web page display. Communication is by Ethernet LAN with SNMPv3 including alarm trapping. It also has provision for temperature compensated charging of an external battery using a supplied TC probe. An LCD display/touchpad is included for local metering, status, and setup.

The Guardian Access 2U is compatible with Unipower’s free PowComsoftware which offers local and remote management through an advanced Windows GUI.
