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.

Specifications

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

Vertiv |NetSure Rectifier Module User Manual (UM1R483000e3) |Rev. 1.0

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.

and 50%-75%-50% at rated output voltage and current, meets YD/T731-2008.

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.

•Filtering:

2. Psophometric noise is ≤ 2 mV typical at 220Vac input,53.5 Vdc output and 30% to 90% of

rated load for more than one rectifier.

b) Wide Band Noise: Complies with YD/T-731-2008.

1. Wideband noise emission is < 20 mV between 25HZ-20kHz according to ETS 300132-2 .

AC Input Ratings

•Voltage: Nominal 208/220/230/240 volts AC, single phase, 3-wire, 50/60 Hz, with an

operating range of 200 to 250 volts. Acceptable input frequency range is 45 to 65 Hz.

•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
