Introduction
Figure 1. Output Voltage vs. Output Current
Output Voltage vs. Output Current,
Max. Output Power 2000W
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 2000W.
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 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.

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
(2000W) as long as the input voltage is within the
range of 176 to 300VAC. 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.

Power Derating Based on Temperature: The rectifier
delivers full power when operating at an ambient
temperature of +55°C (+131°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 +55°C (+131°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 +55°C (+131°C) and +80°C
(+176°F) will result in output power being decreased.
Full power capability is restored when the
temperature decreases to below approximately +55°C
(+131°F). Refer to Figure 3 to view the relationship

between the output power and the ambient
temperature.
b.
WARNING! The module is rated for continuous
operation at full output power up to +55°C (+131°F).
Operation between +55°C (+131°F) and +80°C
(+176°F) will result in output power decrease.
Operation above +80°C (+176°F) is considered
abnormal and should be used on a temporary1 basis
only.
Warning

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.)

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.
b.
•
Current Limiting: The rectifier has a current limit
function. The current limit point can be set
between the range of 4 to 41.7 A, adjustable via
the Controller. The current limit accuracy is
±1.5A when the output voltage ranges from 42 to
58 V. Below 42 V the current will fold back to a
lower value.
c.
Advanced Current Limit Function: The rectifier
has an advanced Current Limit Function. When a
short circuit occurs at the rectifier output
terminals, the rectifier will keep its output current
at a value below the maximum current limit set
point. This function effectively protects the
rectifier and the equipment connected to the
rectifier. When the short circuit fault is cleared,
the rectifier will automatically restore back to
normal operation.
d.
High Voltage Shutdown:
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: 80V, ±5 V;
hysteresis is 15 VAC for restart.
2.
High Voltage Disable Point: 305V, ±5 V;
hysteresis is 10 VAC for restart.
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 85V with output >48V,
max output power is 800W.
2.
At input voltage of 120V with output >48V,
max output power is 1364W.
3.
At input voltage of 154V with output >48V,

Active Load Sharing: The rectifier uses advanced
digital active load sharing technology that maintains
balancing to within 3% of rated current.
•
Hot Swappable: The rectifier is designed to be plugand-play. The rectifier can be inserted or removed
from a live DC power system with no damage. When
the rectifier is plugged into the system, the system

fan fails. Fan failure is detected and reported to
Controller. The fan is not field replaceable.
b.
Fan Control: Fan speed is continuously variable.
When input voltage is within normal range, the
built-in processor adjusts fan speed according to
the rectifier module’s internal temperature and
output power. For example, a higher
temperature or output power increases the fan
speed. This feature can be disabled via the
controller, allowing the fan to run at full speed
regardless of temperature.
•
Paralleling: Up to 32 rectifiers can be connected in
parallel in one system.
•
Communication Failure: The rectifier’s protection
indicator (yellow) will flash should it experience a
communication failure. The failure information will be
reported to the Controller and the Controller will
process the failure accordingly. During a
communication failure, in order to protect the
battery, the rectifier output voltage will automatically
be adjusted as follows. When used with the SCU+
Controller, rectifier output voltage goes to a default
value (53.5 V, which can be modified using the SCU+
Controller). When used with the ACU+ Controller,
rectifier output voltage goes to the ACU+ float voltage
setting (this setting is stored in the rectifier). The
rectifier will revert to normal operation once normal
communication is restored.

Requirements/Recommendations
Rectifier Current Limit
Refer to the system documentation supplied with the system
the rectifier is installed in.
When setting total rectifier current limit, the set point to each
rectifier is the total set point divided by the number of rectifiers.
For example, if the system contains five rectifiers and the
current limit is set to 150 amps then each rectifier has a current
limit set point of 30 amps. If one or more rectifiers are removed
or fail it will take several seconds for the individual set points to
the remaining rectifiers to be reset. In the example given, if one
rectifier is removed the current limit set point will drop to 120
amps (30 amps times four remaining rectifiers) until the
controller can send updated set points to the remaining
rectifiers. This takes a couple communication cycles (several
seconds) after which each rectifier would have a new set point
of 37.5 amps for a total of 150 amps. The total current limit of
the rectifiers should not be set such that the loss of the
redundant rectifiers will cause this temporary set point to drop
below the actual maximum expected load. If batteries are used
on the rectifier output, the batteries should support the load
until the current limit set points can be re-established due to
loss of a rectifier.
Local Indicators
Location and Identification: Refer to Figure 5.
Description: There are three (3) indicators located on the
rectifier’s front panel. The functions of these indicators are as
shown in Table 6.
Note: DC voltage must be present at the rectifier output terminals
(from battery or an operating rectifier) or AC voltage at the
input terminals.
