b)
R48-2000 and R48-2000H: At 25°C ≤ 53dB(A) with fan in high speed. Measurement made at 0.6m
distance in front of rectifier and at same horizontal line of the middle of rectifier.
• EMI/RFI Suppression:
a)
Rectifiers operating in an approved rectifier Mounting Shelf conform to the requirements of FCC
rules Part 15, Subpart B, Class B for Radiated and Conducted emissions limits.
b)
Rectifiers operating in an approved rectifier Mounting Shelf conform to the requirements of
European Norm, EN55022, Class B for Radiated and Conducted emissions limits.
Compliance Information
• EMC: ETSI EN 300 386 class B, FCC CFR 47 Part 15 class B, Telcordia GR-1089-CORE class B.
• Safety: IEC 60950, EN 60950, UL 60950.
Standard Features
• Type of Power Conversion Circuit: High frequency.
• Constant Voltage Mode: For any initial output voltage setting from 42 to 58 volts, output voltage
remains constant regardless of load. This is the normal operating condition, in which loads are being
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 2000W.
• Constant Power Mode: As load increases above approximately 2000W (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 to the current limit setting, output voltage decreases linearly
to maintain output current at the current limit setting.
• Input Protection:
a)
Input Over/Under Voltage Protection: The rectifier will shut down at low or high voltage input; based
on the following voltage levels:
1.
Low voltage disable point 80 V, ±5 V; hysteresis is 10 - 20 VAC for restart.
2.
High voltage disable point 305 V, ±5 V; hysteresis is 10 - 15 VAC for restart.
b)
Between 85 V and 176 V the output power will be derated linearly based on the input voltage as
follows:
1.
At input voltage of 85 V with output >48 V, max output power is 800 W.
2.
At input voltage of 120 V with output >48 V, max output power is 1262 W.
3.
At input voltage of 154 V with output >48 V, max output power is 1700 W.
4.
At input voltage of 176 V and output >48 V, max output power is 2000 W.
