IMPORTANT SAFETY INSTRUCTIONS
General Safety
DANGER! YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to hazards. These procedures should
be performed by qualified technicians familiar with the hazards associated with this type of
equipment. These hazards may include shock, energy, and/or burns. To avoid these hazards:
a) The tasks should be performed in the order indicated.
b) Remove watches, rings, and other metal objects.
c) Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no
voltage or the expected voltage is present. Check for voltage with both AC and DC
voltmeters prior to making contact.
d) Wear eye protection.
e) Use certified and well-maintained insulated tools. Use double insulated tools appropriately
rated for the work to be performed.
Voltages
AC Input Voltages
DANGER! This system operates from AC input voltage capable of producing fatal electrical
shock. AC input power must be completely disconnected from the branch circuits wiring
used to provide power to the system before any AC electrical connections are made. Follow
local lockout/tagout procedures to ensure upstream branch circuit breakers remain de-
energized during installation. DO NOT apply AC input power to the system until all electrical
connections have been completed and checked.
DC Output Voltages
DANGER! This system produces DC power and may have a DC source connected to it.
Although the DC voltage is not hazardously high, the rectifier can deliver large amounts of
current. Exercise extreme caution not to inadvertently contact or have any tool
inadvertently contact an output terminal or exposed wire connected to an output terminal.
NEVER allow a metal object, such as a tool, to contact more than one termination at a time,
or to simultaneously contact a termination and a grounded object. Even a momentary short
circuit can cause sparking, explosion, and injury.
DANGER! Follow local lockout/tagout procedures to ensure DC branch circuit protection
devices remain de-energized during installation at loads, as required.

Rectifier Overview
The rectifier provides load power 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 2000 W. 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 VDC to -58 VDC
(factory set at -54 VDC), output voltage remains constant regardless of load. This is the
normal operating condition, in which loads are being supplied. The rectifier operates in the
Constant Voltage Mode unless load increases to the point where the product of load current
and output voltage is approximately 2000 W.
•Constant Power Mode: As load increases above approximately 2000 W (non-adjustable),
output current continues to increase, but output voltage decreases as required to maintain
constant output power. The rectifier operates 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.
Rectifier Specifications
The specifications are for a single unit only, unless otherwise noted.

DC Output Ratings
1. Voltage: -42 VDC to -58 VDC, positive ground. Output voltage is factory set at -54 VDC.
2. Output Power and Current:
a) 2000 W (41.7 A) @ 200 VAC to 250 VAC input and -48 VDC output.
3. Output Characteristics: Refer to Figure 1 for a graph of output voltage vs. output current.
Figure 1: Output Voltage vs. Output Current
4. Power Derating Based on Input Voltage: The rectifier power varies with changes in input
voltage. It uses an advanced power limitation method. The lower input threshold is 85 VAC. The
rectifier can provide its maximum rated power (2000 W) as long as the input voltage is within the
range of 176 VAC to 300 VAC. 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.

5. Power Derating Based on Temperature: The rectifier delivers full power when operating at an
ambient temperature of +50 °C (+122 °F) or below. The 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
+75 °C (+167 °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 +75 °C (+167 °F) will result in output
power decrease. Operation above +75 °C (+167 °F) is considered abnormal and should be
used on a temporary1basis only.
6. 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.)
Other power rating values are as follows (refer to Figure 3):
a) At an ambient temperature of +65 °C (+149 °F), the power delivered by the rectifier is 800 W.
b) At an ambient temperature of +75 °C (+167 °F), the power delivered by the rectifier is 0 W.
NOTE! If used outdoors under full solar radiation, all the operation temperature ratings are
decreased by 15 °C.
Figure 3: Power Derating Based on Temperature
7. 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.
b) Dynamic: Response time ≤200 us and overshot ≤5 % for load changes at 50 % - 25 % - 50 %
and 50 % - 75 % - 50 % at rated output current.

Vertiv |NetSure R48-2000C Outdoor Rectifier Installation & User Manual (UM1R482000C) |Rev. A

For any step load change within the range of 10 % to 90 % of full load within 50 ms, per Telcordia
GR-947-CORE, the maximum voltage transient will not exceed 5 % of the initial steady state voltage
within 50±10 us. Recovery to within 1 % of the initial steady state voltage does not exceed 1
milliseconds.
8. Filtering:
a) Voice Band Noise: Peak-peak voltage is ≤200 mV at 0 MHZ to 20 MHZ and normal output
voltage.
b) Wide Band Noise: Wideband noise voltage is ≤50 mV at 3.4 kHz to 150 kHz and ≤20 mV at 0.15
MHz to 30 MHz.
AC Input Ratings
1. Voltage: Nominal 120 VAC / 208 VAC / 220 VAC / 230 VAC / 240 VAC, single phase, 3-wire, 50 Hz
/ 60 Hz, with an operating range of 85 VAC to 300 VAC. Acceptable input frequency range is 45 Hz
to 65 Hz.
Permitted Variation: 85 VAC to 300 VAC.
2. Harmonic Content (THD): Meets EN61000-3-2. ≤5 % from 50 % to 100 % of rated output current
at 220 VAC.
3. Inrush Current: Peak does not exceed 1.5 times of the peak value of the maximum steady-state
input current at full load, 220 VAC input voltage, and for any duration of AC input interrupts. Under
the above conditions, standard AC distribution circuit breakers will not trip.

3. Safety: IEC 60950, EN 60950.
Standard Features
1. Type of Power Conversion Circuit: High frequency.
2. 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:
Low Voltage Disable Point: 80 VAC, ±5 V; hysteresis is at least 15 VAC for restart.
High Voltage Disable Point: 305 VAC, ±5 V; hysteresis is at least 10 VAC for restart.
b) Between85 VAC and 176VAC the output power will be derated linearly based on the input
voltage as follows:
At input voltage of 85 VAC with output >48 VDC, maximum output power is 1000 W.
At input voltage of 176 VAC with output >48 VDC, maximum output power is 2000 W.
3. Output Protection:
a) Overload / Reverse Current: The rectifier has a fuse wire in the negative output DC bus. This
fuse is not customer replaceable.
b) Current Limiting: The rectifier has a current limit function. The current limit point is factory set
at 41.7 A. The current limit accuracy is ±1.5 A when the output voltage ranges from 42 VDC to 58
VDC.
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
constant value (factory set at 34.5 A). 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:
•Fixed Control: If rectifier output voltage exceeds a factory set value of 59.5 VDC and the
rectifier is delivering more than 10 % of its rated current, the rectifier shuts down. (The
restart hysteresis is 0.5 V ±0.2 V.)

The rectifier then restarts and a HVSD restart timer starts (factory set at 5 minutes). If
output voltage again exceeds the high voltage shutdown value before the HVSD restart timer
expires, the rectifier shuts down and locks out. Manual restart is then required (by turning
power to the rectifier off , waiting until the LEDs on the rectifier extinguish, then turning
power to the rectifier on). If the rectifier does not experience a high voltage condition
before the HVSD restart timer expires, the restart circuit is reset.
If two or more rectifiers are paralleled, only the rectifier causing the high voltage condition
shuts down.
•Backup: If rectifier output voltage exceeds 59.5 VDC ±0.5 V (non-adjustable), the rectifier
shuts down. The rectifier then restarts and a HVSD restart timer starts (factory set at 5
minutes). If output voltage again exceeds the high voltage shutdown value before the HVSD
restart timer expires, the rectifier shuts down and locks out. Manual restart is then required
(by turning power to the rectifier off, waiting until the LEDs on the rectifier extinguish, then
turning power to the rectifier on).
4. Over-Temperature Protection: The rectifier provides over temperature protection by derating
output power and recovers automatically.
5. Active Load Sharing: The rectifier uses advanced digital active load sharing technology that
maintains balancing to within 5 % of rated current.
6. Paralleling: Up to three (3) rectifiers can be connected in parallel in one system. Do not exceed
the load rating of a single rectifier.
7. Rectifier Output Current Imbalance: When the average current of the system is greater than
10% of full rated current, and a load sharing severe imbalance occurs (such as an output fuse
opens) and the output current drops to zero, then the red fault indicator illuminates.
8. Monitoring Function: The rectifier has a built-in advanced DSP that monitors and controls the
operation of the rectifier.
WARNING! This product is not intended for oil exposure.
CAUTION! Double pole/neutral fusing.
