Rectifier Shelves
The rectifier shelves integrated into the
NetSure
™
211 system are either 1.75"
(1RU) or 3.5" (2RU) high and available
in 19" and 23" widths. These shelves
provide front to back ventilation and
can be mounted directly above or below
other electronic equipment, maximizing
revenue-generating space. Each unit

As load demand grows, the system can be easily
expanded with additional modular components.

Rectifiers
The R48-500 and R48-1000 NetSure
™
rectifiers are rated for 500W or 1000W
watt constant output power when
operated at 208/240VAC nominal input.
The 1000W model rectifier provides
approximately half its rated output when
operated at 120VAC. This auto-sensing
circuit enables each rectifier to automati-
cally adjust its output to the available line
voltage. The rectifier will provide up to
100% of rated power at 45°C.
Controller
The SCU+ and ACU+ (for 2RU systems
only) are powerful control units that en-
able remote monitoring of the main AC
supply, DC power plant, battery backup
and site environment.
The controller enables advanced battery
management such as sophisticated boost
charge control, remaining capacity test-
will operate from 120/208/240VAC and
is equipped to accommodate plug-in AC
connections or open wire line cords.
DC output connection options for each
shelf include terminal blocks, plug-in
DC jumpers for GMT load, and two-hole
compression lugs for breakers. The shelf
with rectifiers is UL Listed and meets FCC
Class B EMI/RFI requirements.
As the temperature increases from 45°C
to 75°C, the thermal power limit circuit
linearly decreases power. In the typical
operating range, these rectifiers have
a total harmonic distortion less than 5%,
and efficiencies greater than 92%
(1000W). Each hot-swappable rectifier
has an integral multi-speed cooling fan
and tri-LED status indication.

basic energy saving functions, the SCU+
is a cost-efficient system component. For
more sophisticated site monitoring the
ACU+ is available as an option for 2RU
systems only. Information and alarms from
a specific site are monitored or checked
