NOTE: The vast majority of IDAS networks are DC powered only.
Typical Power Requirements - IDAS Remotes
Line Powered IDAS Remotes
Remote
Node
• Powering of electronics from a remote source using a copper cable
• Outdoor applications: Use an up-converter to boost voltage to ±190Vdc & use down-converter to drop voltage to 48Vdc at remote end
• Indoor applications: IDAS remotes require much less power (<100VA) and must be below 60V SELV (Safety Extra Low Voltage)
• Shorter distances for IDAS nodes can be met with 48Vdc without elevating the voltage but must be current limited to conform with Class 2 Communication Circuits per Article 725 of NEC
• For safety reasons, each circuit is limited to 100VA
Centralized
Power Source
Centralized
Power Source
Class 2 Requirements
Voltage: < 60Vdc
Power: < 100W
POTENTIAL ISSUES WITH LOCAL POWER ARCHITECTURE
• Proliferation of batteries increases cost, creates ongoing maintenance requirements
• Requires access to AC power at each remote
• Size of power conversion equipment and batteries, even if located in an equipment rack, can become a problem
• Cabinets are ideal for housing and securing electronics, but space consumption and/or aesthetics can be an issue for some venues
SOLUTION
• Centralized battery and power system at the head-end to avoid above mentioned potential pitfalls
SPECIAL REQUIREMENTS FOR INDOOR APPLICATIONS
Type MC Cable
Type MC-OF Cable
Certified electrician
Conduit
• However, deploying a centralized system brings its own challenges with it
• Specifically because Indoor DAS circuits are considered to be accessible to the public, so safety requirements are more rigorous
• The challenges include • Cabling cost to individual remote units
• Cost of using armored cable to be compliant with standards
• In some jurisdictions, cost of installing conduits to pass cable through
• Require the assistance of certified electrical personnel for wiring
WHY DOES IT MATTER?
Issue: Any installation that requires the use of conduit and an electrician will have a significantly higher cost
Goal: Line power the remote units using surface mounted
cable avoiding the cost of both the conduit and the electrician
Solution: Requires use of NEC Class 2 circuits
NEC CLASS 2 REQUIREMENTS
• For a product to be approved and obtain the benefits of NEC class 2 • Voltage <= 60Vdc • Power <=100VA
MAKING IT SAFE – NEC CLASS 2
• Class 2 circuits (Article 725 of the National Electric Code [not article 800])
• Class 2 circuits are considered safe from a fire initiation standpoint and provide acceptable protection from electrical shock
• Class 2 circuits can be installed using conventional surface-mounted cable (no conduit, MC or armored cable)
• Class 2 circuits do not require the authorization of a certified electrical personnel (permitting and licensing)
Class 2 Requirements
Voltage: < 60Vdc
Power: < 100VA
NEC CLASS 2 COMMON MISCONCEPTIONS
• Common misconception about NEC class 2 circuits are that a standard GMT fuse panel can be used a class 2
distribution panel.
• Current limiting panels distribute centralized power over copper cable to multiple remote iDAS nodes
• Panels include circuitry to limit the total power per circuit to 100VA
• Alpha pioneered this solution with the eLimiter™

POWERED iDAS: PRESENT MODE OF OPERATION
MARKET REQUESTS FOR PRODUCT ENHANCEMENTS
• Modularity • Reduce the total number of circuits on the customer interface devices • Minimize disruption to the network in the event of an equipment failure
or product upgrade
• Monitoring & Control • Add the ability to monitor the performance of each circuit as well as the
total system • Add the ability to provision and control circuits
• Extended Reach • PMO designs must be based on the battery cutoff voltage of 42Vdc, or
41.25Vdc when voltage drop from battert bank to eLimiter is considered • Increase the voltage to extend the distance served
• Improved Efficiency
INTRODUCING eLIMITER+
• Next generation iDAS line power system that distributes -57Vdc to remote equipment

Powering Outdoor Distributed Antenna System
• The main interface unit, optical converter devices & controller are
typically installed in a BTS hotel and optical fiber cables connect the
BTS to the RAUs.
• Outdoor remote access units are generally powered from an AC voltage
source as it’s readily available on the utility pole. DC powered remotes
are available but require a rectifier system.
• Power requirement for remotes can vary from 300W to 1600W
depending on the number of bands it’s configured to support.
• If the remotes require battery backup protection, then an outdoor
enclosure with outdoor rated AC UPS and batteries are required.
• Aesthetics of the cabinet is an important consideration especially if
these solutions are deployed in urban areas.
• RAUs are installed outside the power enclosure since they are
hardened for outdoor applications. However, if aesthetics become an
issue with too many items on a pole, then an enclosure/shroud to
conceal all items would be one possible solution.
