1.2 Warnings
Please read this manual prior to use to become familiar with the product’s numerous features and operating procedures. To
maintain the maximum degree of safety, follow the sequences as outlined.

Before using the product, read all instructions and cautionary markings on the product and on any equipment connected to the
product.
CAUTION – Unless otherwise noted, product usage that is not recommended or sold by the product manufacturer can result in
riskofre,electricshock,orinjurytopersons.
CAUTION – Do not operate the product if it has been damaged in any way. Return damaged products to their manufacturer for
repair or replacement.
CAUTION –
A) Elevated Operating Ambient - if installed in a closed or multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature of 55°C.
B)ReducedAirFlow-Installationoftheequipmentinarackshouldbesuchthattheamountofairowrequiredforsafe
operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given
to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
F) The supply input voltage ranges between -58Vdc to -40 Vdc (+/- 0%).
G) Rated Output Power (kW) = Input Voltage (Vdc) *275 (A).

2.0 Introduction
In a split Radio Base Station (RBS) architecture the typical RBS consists of a Base Band Unit (BBU) and Remote Radio
Heads (RRH) connected by cabling. Power to the RRH is provided through copper cables traveling from the base station
to the top of the tower or roof top. This creates a conductive path, making the active equipment at the top and the base of
the site vulnerable to damage by direct lightning strikes. Protection systems installed in front of both the BBU and the RRH
must be able to withstand direct lightning currents in order to protect the sensitive equipment. Raycap’s RRH solutions
featuring Strikesorb®SPDtechnologysignicantlyenhancethereliability&availabilityoftheRRHsitebyprovidingsuperior
electrical protection at the RRH and BBU. PowerPlus is Raycap’s solution for power transmission to the RRH units of a DAS
Telecommunication site. PowerPlus is a system installed at the PSU output that boosts the voltage at the base of a cellular site
to overcome the voltage drop on the DC power cables that provide power to the RRHs.

5. General Description
5.1 Functionality
• The PowerPlus 100-3-1U system is intended to boost the voltage of a telecom power supply to reduce
the current on the power cables. The output voltage of the system remains constant to a value that is
usercongurableduringitsinstallation.
• By reducing the current, the cable power losses are reduced, and the total system becomes more
efcient.
• Additionally,thePowerPlus100-3-1Uisbenecialwhenoperatingonbatterybackuppowerduringa
poweroutage.ThePowerPlus100-3-1Uwillmaintainaconstantoutputvoltage(ascongured)tothe
radio while the battery discharges. This allows the radio to operate for a longer period of time while
the batteries discharge.
5.2 Modes of Operation
• The PowerPlus 100-3-1U system is composed of a mounting rack and up to three pluggable modules.
• The PowerPlus 100-3-1U system may operate in one of two modes. The Single Mode and the
Parallel Mode.
• The voltage output of each module is intended to be connected to individual loads when the device is
conguredtooperatein Single Mode.
• ThemoduleoutputsmaybeconnectedinparallelwhenthedeviceisconguredtooperateinParallel
Mode.Inthisconguration,theloadissharedbetweentheinstalledmodules.
