2.1Description
The Helios DC System 4000/48 is a positive ground, -48 V DC nominal power system consisting of
one control and distribution cabinet and one or more rectifier cabinets. It is available in capacities
of 1500, 3000, 4000 and 6000 A. Auxiliary distribution cabinets can be added as required for additional distribution. Remote monitoring, temperature compensation and battery disconnect
options are also available. The 1500, 3000 and 4000 A versions use internal -48 V bussing and
external BR+ bussing, while the 6000 A version uses overhead bussing.

Cables are used for inter-cabinet connections (1500, 3000 and 6000 A systems) or connections to
the overhead busbars (6000 A system) for ease of expansion on live systems. In a 1500, 3000 or
4000 A systems, the power system battery return (BR) busbar is mounted externally from the cab-
inet to facilitate the connections of the battery return cables. In a 6000 A system, a separate BR
busbar dedicated to the battery returns for the loads is mounted externally from the overhead
busbar duct to facilitate the connections of the load battery return cables.
The Helios DC System 4000/48 provides a variety of monitoring and alarm features, such as high/
low float and high/low voltage alarm, high voltage shutdown, fuse and breaker alarm and rectifier
failure alarms.
The Helios DC System 4000/48 uses Helios Rectifiers 200I/48, Helios Rectifiers 200E/48 or Helios
Rectifiers 100/48 connected in parallel as building blocks to reach the maximum capacities. The
Helios Rectifiers 200I/48 operate from a 380 V to 415 V three phase, 50 or 60 Hz AC source. The
Helios Rectifiers 200I/48 operate from a 480 V three phase, 50 or 60 Hz AC source. The Helios
Rectifiers 100/operate from a 208 V to 240 V single phase, 50 or 60 Hz AC source.
The 1200 A rectifier cabinet accepts up to six Helios Rectifiers 200I/48 or 200E/48, while the 1000
A rectifier cabinet accepts up to 10 Helios Rectifiers 100/48.
The control and distribution cabinet and the auxiliary distribution cabinets are available with
distribution busbar risers of 2000 A or 3000 A capacity.
The cabinets are seismic qualified to zone 4 (Bellcore) when anchored to a concrete floor whose
compressive strength is at least 2.11 kg/mm
The cabinets are seismic qualified to zone 2 without the seismic kit.

(3000 psi) and when equipped with a seismic kit.
1200 A rectifier cabinets
The cabinets are equipped with a ventilated, lockable door, a ventilated top cover and two rear
ventilated panels.
In many applications, such as with DMS, a consistent single-point ground (SPG) topology must be
maintained for all associated equipment. The Helios DC System 4000/48 complies with this
requirements for single-point grounding (the isolation kit is required).
2.2Applications
The Helios DC System 4000/48 is designed to operate with DMS systems or any other telecommu-
nication systems whose input is nominal -48 V DC and whose current requirements do not exceed
6000 A capacity.

PECIFICATIONS
3.1Framework
The Helios DC System 4000/48 uses cabinet type frameworks. The same cabinet design is used for
the main control and distribution cabinet, the auxiliary distribution cabinets and the rectifier cabinets. The cabinet is always equipped with a front door and door frame (lockable, equipped with
ground straps, and easily removable for installation or maintenance access), a ventilated top
cover made of non-flammable plastic, and two ventilated rear cover panels (equipped with ground
strap and easily removable for installation and maintenance access). Bussing and equipment
(controller, rectifiers, distribution panels, etc.) are added as required, depending on the use of the
cabinet. Seismic bracing is also available as options.
When using the Cable Trough, overhead cabling cannot enter from the front or rear of the system.
It must be confined to the system foot print and enter at the ends of the lineup.
The cabinets may be either top or bottom cabled as determined by the location of the bussing.
