SPECIFICATIONS
1. SYSTEM
1.1 DC Operating Voltage
1.1.1 Nominal: -48Vdc.
1.1.2 Range: -42Vdc to -60Vdc.
1.2 Environmental Ratings
Note: See also ‘Environmental Ratings’ in the Rectifier Module section.
1.2.1 Operating Ambient Temperature Range: 0°C to +40°C (+32°F to +104°F).
1.2.2 Storage Ambient Temperature Range: -40°C to +65°C (-40°F to +149°F).
1.2.3 Humidity: This system is capable of operating in an ambient relative humidity range of 0% to
95%, noncondensing.
