1�4 Electrical Safety WARNING! The DC input to the modules (and the converter system) – though not dangerous in volt- age – has a high short circuit current capacity that may cause severe burns and electri- cal arcing. The DC output is a potentially dangerous voltage. Do not touch the output connections when under power.
2� Product Overview • High efficiency >92% for increased OPEX savings and reduced carbon footprint • High temperature tolerance for installation in harsh OSP cabinet environment • Industry leading power density enabling 16 channels in a compact 2RUx6” footprint • High reliability convection-cooled design with optional fan tray The LPS36 Compact is a modular DC to DC up-converter system designed for distributed power communications applications using +/- 190Vdc (RFT-V circuit) over existing copper network.
3� Product Specifications Electrical Input voltage: -40 to -60Vdc Recommended breaker: Output voltage: ±190Vdc (RFT-V) Power: 96W nominal per output, >92W for worst case conditions (4 outputs per module) Efficiency: >92% Regulation: <2% no load to full load <1% line Output Noise: Wide band: <500mV...

4� Site Evaluation and Pre-Installation 4�1 Pre-Installation Requirements 4�1�1 Effective Capacitance The effective capacitance of each output of the LPS36 is 2.7 microfarads maximum between the output connections to the telecommunications network and 0.5 microfarads between each output connection to the telecommunica- tions network and earth ground.
5� LPS36 Compact System Installation This chapter is provided for qualified personnel to install an LPS36 Compact system. 5.1 General Instructions This chapter provides cabling details and notes on cable sizing for DC applications. Connections to the converter system must comply with all the local codes and ordinances. 5.2 Safety Precautions WARNING! The DC input to the modules (and the converter system) –...
CAUTION! The LPS36 Compact is suitable for connection to the central office. The LPS36 Compact must be grounded via a copper ground conductor. Before making connections all bare grounding connection points to the LPS36 Compact must be cleaned and coated with an anti-oxidant solution. Before making connections all surfaces on the LPS36 Compact that are un-plated must be brought to a bright finish and treated with an anti-oxidant solution.
