With -48VDC output at 60A to 600A, the feature-rich system combines high-power output of bulk units with bullet breaker flexibility

January 7, 2020 (Coral Springs, FL) – UNIPOWER, a world-leading provider of quality high-efficiency power electronics and energy conversion systems and power supplies, today introduced its 19-inch rack-mount DC power system, the Guardian Access M38.

Based on customer feedback and market demand, the company designed the system to “combine the high-power output of our bulk systems with the ease and flexibility of a bullet breaker configuration,” according to John Ely, vice president of marketing. “The distribution can be totally configured in the field.”

The first in a new line of NPS products for the North American market, the Guardian Access M38 is a highly configurable system that provides output of -48VDC with current from 60A to 600A as needed, which can be shared between the load and battery charge current that is programmable via the controller.

Included are three rectifier shelves with up to 11 Guardian family high-efficiency hot-swap rectifiers which are internally fan-cooled with speed control, a function of load and temperature to minimize acoustic noise.

Ely added that the ACX Advanced remote access controller monitors system parameters, controls rectifier output, provides alarms for system failures and is replaceable in the field.

The easily installable system can be programmed via remote PC webpage display, allows communication by Ethernet LAN with SNMPv3 including alarm trapping, and temperature compensate external battery charging with a supplied TC probe. An LCD display is included for local metering, status and set-up, he said.

Other key features include three LED alarm/status indicators, 10 Form-C relay alarms, up to 20 load circuits and standard 600A LVD with battery.  In addition, the new Guardian Access M38 is compatible with UNIPOWER’s free PowCom software, offering local and remote management through an advance Windows graphical user interface (GUI).

Ely said UNIPOWER is the first company in the industry to offer a three-year warranty with the Guardian Access M38, a full year increase over most of its competitors.
