Datasheet for PDU-6A - Radio Frequency Systems
Product Data Sheet
PDU-6A
Power Distribution Unit, indoor, 6 channels, automatic current sensing
Product Description
The PDU-6A power distribution unit (PDU) from RFS can be used with single or dual Tower
Mounted Amplifiers (TMAs). It powers up to six TMAs through the bias-T. Its intelligent self-learning
current ability allows multiple TMAs with different current draws to be automatically powered, without
complex adjustments at the site. Upon a manual reset of the front panel switch the PDU measures
the current flow in each of the DC output channels. Once a DC output channel is enabled the normal
operating current is saved and if a significant change in operating current (±30mA) is detected on
any channel of the PDU an alarm state is raised. The PDU displays individual TMA monitoring status
via 6 LEDs located on the front panel (1 per channel). The PDU-6A is extremely compact and
lightweight, and allows for easy installation in a standard 19” rack. Additionally, its superior design
ensures maximum reliability in the most extreme environmental conditions. The following cables are
included with the units: Power supply cable, alarm cable,and grounding cable. A DC-injection cable
can be purchased separately.
Features/Benefits
• Self-learning current ability that works with a wide variety of TMAs – Eliminates complex site adjustments
• 22-50 volt DC input range that is compatible to most BTS’s – Provides flexibility for overall system design
• 19 inch rack mount design – Facilitates easy installation
• Summary relay alarm output – Adds additional monitoring
• LED status indicators for each individual TMA – Ensures system reliability
