L Series
7 Models Single Output Up To 250 Watts
1U Redundant Hot Swap Power Supplies

Description
The L Series is part of Deltron's SlimLine group of 1U high power supplies. This series of single output self-cooled models is rated up to 250 watts, with each unit measuring 1.58”H x 1.86”W x 11.32”L. Uniquely packaged and highly compact, L Series modules fit a wide range of industrial, telecom and computer networking applications. These hot-pluggable units can be paralleled for additional power or used in combination with other models to meet multiple output requirements. When used in Deltron’s RA20A racking system, up to six L Series units can be mounted in a 1U high rack space to provide 1500 watts.

Designed to meet applicable NEBS standards, units feature a proven topology coupled with excellent thermal management to achieve outstanding performance and safety. DC Good feature provides logic signal for monitoring power supply status. All models are available with redundancy option for parallel or N+1 hot pluggable applications. Low voltage models include N channel ultra low drop Or-ing circuit to maintain power supply efficiency.

L Series Rack System
The RA20A 1U high, 19”-wide racking system is available for paralleling or N+1 redundant systems. The 1.75”-high by 12.0”-deep rack accommodates up to six L Series power supplies providing up to 1500 watts. Racks include a top cover for added strength and protection.

Each power supply plugs into the backplane and is securely held in place by removable front panels. Individual output and signal connections are made via rear accessible Euro-style terminals and headers. Two 3-terminal Euro-style input connectors are provided, one for each half of the rack. Racks are designed to accept either EIA or Bellcore NEBS mounting and heavy-duty solid-bearing slides.

Option 04 is available for 250 watt models with voltage ratings of 12 volts or greater. Not available in combination with Option 08.
