Dual Inline Power Distribution Unit

Time and space are important considerations when selecting and installing wireless components at

base transceiver station sites. The simple, compact design of ADC’s ClearGain Power Distribution

Unit (PDU) is intended to help service providers save both. From a compact unit that is easily mounted

on a wall or in a rack, the ClearGain PDU provides power and alarming for up to three ClearGain

Tower-Mounted Amplifiers.

• Provides power and alarm functions for on-site monitoring of up to three dual-inline masthead

units (MHUs)

• Monitors condition of feeder cable

• Wall or rack-mountable to fit available space

• LED indicators for alarm functions

• Simple, compact design allows for easy installation and connections

• AISG compliant

The ClearGain Dual Inline TMA system is modular, consisting of an MHU and a PDU, providing full

compatibility with all base stations.

The ClearGain Dual Inline PDU is an integrated unit that provides power and alarm functions for the

ClearGain TMA system. The PDU monitors the current of the MHU. If an MHU fails, the ClearGain Dual

Inline PDU gives an alarm indication. The ClearGain Dual Inline PDU also monitors the condition of the

feeder cable. Alarm indicators identify failure in the feeder cable or MHUs and in which MHU the

failure occurred, providing fast and easy on-site diagnostics.

The flexible design of the ClearGain Dual Inline PDU allows it to be rack-mounted or mounted indoors

on the wall or on the side of a BTS cabinet.

An external Bias-T unit is used in conjunction with the Dual Inline PDU and is designed to connect

directly into the BTS coaxial connector. Bias-T units are available with various connector types, with

gas tube arrestors for lightning protection on the ANT and MHU ports. Quarter wave stub lightning

protection is integrated on the BTS port of the Bias-T units.
