LD Series
4 Models    Single Output    Up to 2000 Watts
2U Redundant Hot Swap or
Embedded System Power Supplies


Description
The LD Series is part of Deltron’s SlimLine2 group of 2U high-power, high-density supplies. Rated up to 2000 watts, these single output models measure only 3.16"H x 3.48”W x 12.93”L. System integration is facilitated through a choice of two interfaces. Standard configuration includes a Positronic PCI connector for a reliable, cost-effective hot pluggable interface. Optional field terminations enable the interfacing of units into an embedded system via studs and screw terminals. 48VDC models offer a high-density front-end solution for powering Intermediate Bus Converters (IBCs).

LD Series modules fit a wide range of high power requirements ranging from heavy duty industrial applications to fault tolerant front-end networking and computing applications. Units can be paralleled for additional power or used in combination with other models to meet multiple output requirements. When used in Deltron’s RA120A or RA120B racking system, up to four LD Series units can be mounted in a 2U high rack space, providing up to 8000 watts.

Designed to meet applicable NEBS standards, units feature a proven topology coupled with excellent thermal management to achieve outstanding performance and safety. Power Fail, DC Good, Hi Temp, and Fan Fail features provide TTL-compatible logic signals for monitoring power supply status. IEEE 802.3at compliance option is available for Power over Ethernet (PoE) applications. All models are available with redundancy option for parallel or N+1 hot pluggable applications.

LD Series Rack Systems

Two racking systems are available, each 2U-high and accommodating up to four LD units providing a total output of 8kW. The RA120A rack offers hot-pluggable configuration for paralleling or N+1 redundant operations. Each power supply plugs into the backplane and is securely held in place. Individual output and signal connections are made via rear accessible studs and shrouded headers. A heavy-duty barrier block is provided for input connections. The RA120B rack holds field-terminated units. Accessory bus bars are available for paralleling outputs. Racks are designed to accept either EIA or Bellcore NEBS mounting.
