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.
•
Ventilation Requirements: The rectifier is fan cooled and utilizes front to back forced ventilation. A
rectifier must be mounted so ventilating openings are not blocked and temperature of the air entering
the rectifier does not exceed the Operating Ambient Temperature Range stated above.
•
Single Rectifier Audible Noise: The audible noise at any point two feet from any vertical surface of a
Rectifier Mounting Shelf (with one rectifier installed and fans operating) does not exceed the following
limits. The audible noise was measured with the fan control circuit enabled. A Sound Level Meter
conforming to ANSI S1.4 was used.
a)
50dB-A maximum at less than 32°C ambient, half load or less.
b)
60dB-A maximum at less than 32°C ambient, full load.
c)
70dB-A maximum at greater than 32°C ambient, full load.
•
EMI/RFI Suppression: Rectifier operating in an approved Module Mounting Shelf conform to the
requirements of FCC rules Part 15, Subpart B, Class B for Radiated and Conducted emissions limits.
Compliance Information
•
Safety Compliance: This unit meets the requirements of UL 60950-1, Standard for Information
Technology Equipment, and is UL Recognized as a power supply for use in Telephone, Electronic Data
Processing or Information Processing Equipment. This unit meets the requirements of CAN/CSA 22.2,
No. 60950-00 and is tested and Certified by UL ("c UR") as a Component Type Power Supply.
•
The rectifier is RoHS 5/6 compliant.
•
NEBS Compliance (when used in a compliant system): Compliance verified by a Nationally Recognized
Testing Laboratory (NRTL) per GR-1089-CORE and GR-63-CORE. Contact Vertiv for NEBS compliance
reports.
Standard Features
•
Type of Power Conversion Circuit: High frequency.
•
Constant Voltage Mode: For any initial output voltage setting from 23.5 to 28.5 volts, output voltage
remains constant regardless of load. This is the normal operating condition, in which loads are supplied
and batteries are float charged. Rectifiers operate in the Constant Voltage Mode unless load increases
to the point where the product of load current and output voltage is approximately 2500W (R24-2500)
or 3000W (R24-3000).
•
Constant Power Mode: As load increases above approximately 2500W (R24-2500) or 3000W (R24-
3000) (non-adjustable), output current continues to increase, but output voltage decreases as required
to maintain constant output power. Rectifiers operate in the Constant Power Mode unless load
continues to increase to the point where the current limit setting is reached.
•
Constant Current Mode: If load increases above the current limit setting, output voltage decreases
linearly to maintain output current at current limit.
