Environmental Specifications
ALL MODELS (Unless Otherwise Specified)
0 °C to +50 °C at 100% rated load.
-40 °C to +85 °C. For Liquid Cooled models, liquid must be drained before storage
Up to 9,842 feet above sea level (3,000 meters)
Up to 30,000 feet above sea level (9,144 meters)
Operating Sinusoidal Vibration MIL-STD-810G Method 528 Procedure I (Type 1): NEBS Office
Vibration Environment, Alternate Procedure Operating Random Vibration: IPC-9592B Class 1
Non-Operating Vibration (Packaged): IPC-9592B Class 1; MIL-STD-810G, Method 514.6, Procedure 1,
Category 7, Table 514.6C-VII General Exposure
MIL-STD-810G Method 516.6 Procedures I, II, IV, VI
NSTA for <100 lbs.; MIL-STD-2073-1 >100 lbs.
Cooling and Audible Noise
<65 dBA with 80% load @ 30 °C at nominal input voltage with Smart Fan algorithm to be optimized
based on module and rack thermal sensors. When modules are inhibited via software control, the
fan speed is reduced to idle and acoustic noise is <46 dBA. With modules off via front panel switch
fans are at idle for 1 min, and off for 9 min.
1.3.2 Electrical Specifications
The electrical specification for each module type is dependent on if the module is operating in voltage mode or
current mode. Table 1-5 lists the electrical specifications when operating in voltage mode and Table 1-6 lists
the specifications when operating in current mode.
