High Density Remote Power Supply Unit (HD R-PSU)

SKU: 0101-0066 Categories: ,

The Tellabs 1000 Multi-service Access Platform (MSAP) Series High Density Channel Bank Assembly (HD CBA) Remote Power Supply Unit (HD R-PSU) plug-in card converts standard -48 V DC from batteries or a rectifier into the voltages required by the common control equipment and plug-in cards located in a HD CBA.

  • Low thermal dissipation
  • Low output voltage alarm
  • Over-voltage/over-current shutdown
  • Thermal overload protection
  • Reverse input polarity protection
  • Programmable ringing generator
  • High-efficiency switching DC-DC converter
  • Compatibility with the Tellabs 1000 series HD CBA only

Superior Reliability

A Tellabs 1000 series HD CBA requires only one HD R-PSU card; however, a second dedicated power supply slot allows for redundancy. When two HD R-PSUs are installed, they share the total power load to the HD CBA. In addition, if one HD R-PSU fails, the second carries the total power load. The HD R-PSU card features input fusing to protect redundancy.


Efficient Operations

The HD CBA R-PSU card also generates sine wave ringing voltage for use by the subscriber interfaces. The card uses a DC-to-DC switching converter for high efficiency and low thermal dissipation.


Ease of Maintenance

LEDs and receptacles on the faceplate of the HD R-PSU plug-in card have the following uses. Visual LEDs to identify quick operations, troubleshooting and fusing conditions. Three system voltage sampling jacks are also present for +5Vj ack, -48V jack, and Ground.
