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.
1.2.4 Altitude: The maximum operating ambient temperature should be derated by 10°C at an
elevation of 10,000 feet above sea level. For elevations between 3,000 feet and 10,000 feet,
derate the maximum operating ambient temperature linearly.
1.2.5 Heat Dissipation: With Rectifier Module output adjusted to 54.48 volt DC at rated full load and
nominal input voltage.

1.2.6 Ventilation Requirements: The Rectifier Modules are fan cooled and utilize front to back
forced ventilation. The Power Bays must be mounted so ventilating openings are not blocked
and temperature of the air entering the Rectifier Module shelf does not exceed the Operating
Ambient Temperature Range stated above.
1.2.7 Audible Noise: The audible noise does not exceed the following when measured at any point
two feet from any vertical surface of a Power Bay and five feet from the floor using a Sound
Level Meter conforming to ANSI S1.4.

1.2.8 EMI/RFI Suppression: Rectifier Modules operating in a Power Bay conform to the
requirements of FCC rules Part 15, Subpart B, Class A for Radiated and Conducted emissions
limits.
1.2.9 Surge Protection: Compliance with EN61000-4-5 Installation Class 4, and capable of
withstanding surges per ANSI/IEEE C 62.41-1991 Category B across the input terminals.
Note: This level of protection is a widely used standard for telecommunications power
equipment. As with all such equipment, it is the end user's responsibility to provide an
adequately sized Surge Suppression Device at the commercial power service entrance of
the building that reduces all incoming surges to levels below the classes/categories
stated for the equipment.
1.2.10 ESD Protection: Complies with EN61000-4-2 Level 4 (8kV contact).
