RST Power Supply Unit (R-PSU)
The Tellabs 1000 Remote Power Supply Unit (R-PSU) plug-in card converts standard -48 V DC from batteries or a UPA into the voltages required by the common control equipment and plug-in cards located at the Tellabs 1000 MSAP Series. The R-PSU card also generates sine wave ringing voltage for use by the subscriber interfaces. The card employs a DC-to-DC switching converter for high efficiency and low thermal dissipation. The R-PSU features input fusing for redundant source coordination.
Features
- High-efficiency switching DC-DC converter
- Reverse input polarity protection
- Output over-voltage and over-current shutdown
- Low output voltage alarm
- Low thermal dissipation
- Programmable ringing generator
Features
High Reliability
Only one R-PSU is required to power an RST shelf; however, a card slot is provided for an additional redundant R-PSU. And, the R-PSU features input fusing for redundant source coordination
Efficient Power
The R-PSU uses a DC-to-DC switching converter for high efficiency power generations in a compact form-factor.
Low Thermal
The R-PSU uses a DC-to-DC switching converter for high efficiency and low thermal dissipation to minimize impact on surroundings
