STATIC WARNING
This equipment contains static sensitive components. The warnings listed below must be
observed to prevent damage to these components. Disregarding any of these warnings may
result in personal injury or damage to the equipment.
1. Strictly adhere to the procedures provided in this document.
2. Before touching any equipment containing static sensitive components, discharge all static
electricity from yourself by wearing a wrist strap grounded through a one megohm resistor.
Some wrist straps have a built-in one megohm resistor; no external resistor is necessary.
Read and follow wrist strap manufacturer’s instructions outlining use of a specific wrist strap.
3. Do not touch traces or components on equipment containing static sensitive components.
Handle equipment containing static sensitive components only by the edges that do not have
connector pads.
4. After removing equipment containing static sensitive components, place the equipment only
on conductive or anti-static material such as conductive foam, conductive plastic, or
aluminum foil. Do not use ordinary Styrofoam™or ordinary plastic.
5. Store and ship equipment containing static sensitive components only in static shielding
containers.
6. If necessary to repair equipment containing static sensitive components, wear an
appropriately grounded wrist strap, work on a conductive surface, use a grounded soldering
iron, and use grounded test equipment.

INTRODUCTION
Overview
The rectifier provides load power, battery float current, and battery recharge current during normal
operating conditions. The rectifier is a constant power design. The rectifier is rated at its maximum
output power. This means that, within the normal operating ambient temperature range and input
voltage range, the maximum available output power is a constant 3000W. Within these ranges, the
rectifier operates in one of three modes, depending upon load demands. Transition between
modes is completely automatic. If ambient temperature rises above or input voltage falls below
acceptable values, the rectifier continues to operate but at derated output power levels.
•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 3000W.
•Constant Power Mode: As load increases above approximately 3000W (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.

DC Output Ratings
NOTE! A current limitation can be set by the User and the output voltage level is set through
the controller.
•Voltage: Nominal -48 volts DC, positive ground. Output voltage is adjustable from -42 to -58
volts DC via the associated Controller.
•Output Power and Current: 3000W (62.5A) @ 208/220/230/240VAC input and -48VDC
output.
•Output Characteristics: Refer to Figure 1 for a graph of output voltage vs. output current.
Figure 1: Output Voltage vs. Output Current
•Power Derating Based on Input Voltage: The rectifier power varies with changes in input
voltage and output voltage. It uses an advanced power limitation method. The lower input

threshold is 85 VAC. The rectifier can provide its maximum rated power (3000W) as long as
the input voltage is within the range of 176 to 305VAC. Below 176 VAC, and down to 85 VAC,
the rectifier will continue to operate normally but will be in a power derating mode. The
relationship between the output power and input voltage is illustrated in Figure 2.
Figure 2: Power Derating Based on Input Voltage
•Power Derating Based on Temperature: The rectifier delivers full power when operating at
an ambient temperature of +50°C (+122°F) or below. Each rectifier continuously monitors
the ambient temperature surrounding the power conversion circuit. If this temperature for
any reason (such as a high ambient temperature) increases above approximately +50°C
(+122°F), the rectifier will not shut down. Rather, the rectifier limits its maximum output
power to maintain the temperature of the power conversion circuit within design
parameters. Operation between +50°C (+122°F) and +70°C (+158°F) will result in output
power being decreased. Full power capability is restored when the temperature decreases
to below approximately +50°C (+122°F). Refer to Figure 3 to view the relationship between
the output power and the ambient temperature.
WARNING! The module is rated for continuous operation at full output power up to +50°C
(+122°F). Operation between +50°C (+122°F) and +70°C (+158°F) will result in output power
decrease. Operation above +70°C (+158°F) is considered abnormal and should be used on a
temporary1basis only.
Temporary Operation at Abnormal Temperature:Temporary operation is defined as a period of
not more than eight consecutive hours per day, and a total of not more than 15 days in a year.
(This refers to a total of 120 hours in any given year, but no more than 15 occurrences in that one-
year period.)

•Regulation:
a) Static : Steady state regulation is ±0.6% as controlled within the rectifier for any and all
combinations of load from no load to full load, input voltage, and input frequency at a
constant ambient temperature. The associated system Controller may provide increased
regulation.

For any step load change within the range of 10% to 90% of full load within 1 milliseconds,
per Telcordia GR-947-CORE, the maximum voltage transient will not exceed 5% of the initial
steady state voltage within 250±10 microseconds. Recovery to within 1% of the initial
steady state voltage does not exceed 4 milliseconds.
