Installation DLM-E 3kW & 4kW Series Power Supplies
2.5 Location, Mounting, and Ventilation
The DLM–E system supply is designed for use in rack mounted applications. Ensure that
sufficient space is allowed for cooling air to reach the ventilation inlets on the front of the unit,
and for fan exhaust air to exit from the rear of the unit.
2.5.1 Unit Dimensions
Dimension Height Width Depth Weight
Standard 3.5 in 19 in 20 in 40 lbs
Metric 87.6 mm 482.6 mm 508 mm 18.2 kg
2.5.2 Rack Mounting
The supply is designed to fit in a standard 19" equipment rack. Use adjustable support angles
such as Hammond RASA22WH2, or a support bar such as Hammond RASB19WH2. Bolt holes
in the chassis sides are provided for rack mount slides such as the ZERO #C300S18 slides.
Be sure to provide adequate support for the rear of the unit while not obstructing the exhaust
outlets at the rear of the unit.
CAUTION!
Rack mounting bolts must not extend more than
3/16 " into the side of the
power supply.
2.5.3 Ventilation
The DLM–E system supply is fan–cooled, so it requires unobstructed space on the front
ventilation inlets and space at the rear for the ventilation exhaust. The following temperature
ranges apply for the best results when operating or storing the unit.
Operating Ambient Temperature 1 Storage Temperature Range
0 to 50° C with no derating. –40 to +85° C
1. From 50 to 70° C, derate 2% per °C.
From 40 to 70°C, derate 2% per °C below 190 VAC with single or three–phase inputs.
