1EN609DRA-NS4015 / 0913
A safe, reliable and efficient AC to DC power system
intended for 400V DC critical power applications.
Description
The NetSure
™
4015 is an AC to DC power system designed for applications operating
up to 400V DC. The foundation of the system is our patented, next generation 15 kW
eSure
™
rectifier, featuring high frequency switching technology in a compact package.
Equipped with these rectifiers, this 400V DC power system offers high efficiency over
a wide operating range in addition to exceptional NetSure
™
reliability.
Designed for easy deployment in lab evaluation or field installations, all components
of this system fit into standard 19" IT racks. The three major components are:
1. Power and Control Sub-Rack (6U)
2. Load Distribution Sub-Rack (6U)
3. Battery Tray(s) (4U each)
The NetSure
™
4015 is a configurable system that can be integrated into a 24U or 42U
tall rack, either with or without batteries.
Safety features include opera-
tion with high resistance
mid-point ground. With
permanent high resistance
between both the positive and
negative busses and ground
[see Figure 1], personal safety
is increased. Available current
that could accidentally flow
through an individual or equip-
ment from line to ground is
limited to a level consistent
with today’s -48V DC systems.
An independent, online ground fault detection (GFD) system is included to alert users
to unintended insulation breakdowns in the system. The NetSure
™
4015 can also be fac-
tory configured for other grounding topologies upon request.
