The Unipower Aspiro 2U is a compact 2U high 19″ or ETSI rack-mounted, integrated dc power system providing an output of -48Vdc. The system can accommodate up to 4 Aspiro family high efficiency hot-swap rectifiers. A total loadcurrent of 60A / 3.2kW is available with a battery charge current up to 30A 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 systems offer full front access for cable connections with an optional push-pull mounting bracket for either 19″ or ETSI mounting..

The dc output circuits can provide up to 8loads with breakers rated from 1A to 30A. 2additional circuitbreakers providebattery protection. A programmable 125A low voltage battery disconnect (LVBD) 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. Two digital inputs and outputs are also provided as well as a micro SD 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 Aspiro 2U is compatible with Unipower’s free PowCom software which offers local and remote management through an advanced Windows GUI.
