High efficiency 3500 watt constant power rectifiers
reduce energy costs and heat loss.
Description
The NetSure
™
722 Bulk Output Power System is intended for use to expand or
replace legacy -48V DC rectifiers while retaining the site’s existing distribution
power board. It can be used with any -48V DC power system, regardless of vendor
or plant type. Accommodating up to twenty-nine high efficiency 3500 watt rectifiers
per system, the NetSure

722 system contains a powerful, microprocessor-based control system
capable of monitoring and controlling all of the rectifiers in the system. The ACU+
controller also provides output alarming as well as monitoring of external alarms and
signals. It features a 4 x 16-character alphanumeric display, which can be activated at
the touch of a keypad, and remote access via Ethernet is provided with internal web
pages and SNMP.
