INTRODUCTION

Overview

The rectifiers provide load power, battery float current, and battery recharge current during normal operating

conditions. The rectifiers are a constant power design. The rectifiers are rated at their maximum output power.

This means that, within the normal operating ambient temperature range and input voltage range, the

maximum output power available is a constant 2500W (R24-2500) or 3000W (R24-3000). Within these

ranges, the rectifier operate 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,

rectifiers continue to operate but at derated output power levels.

•Constant Voltage Mode: For any initial output voltage setting from 23.5 to 28.5 volts, output voltage

remains constant regardless of load. This is the normal operating condition, in which loads are 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 2500W (R24-2500)

or 3000W (R24-3000).

•Constant Power Mode: As load increases above approximately 2500W (R24-2500) or 3000W (R24-

3000) (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

•Voltage: Nominal +24 volts DC, Negative Ground. Output voltage is adjustable from 23.50 to 28.50 volts

DC via the associated controller.

•Current (One 2500W Rectifier Module): 87.7A at 28.5VDC to 104.2A at 24.0VDC.

•Current (One 3000W Rectifier Module): 105.3A at 28.5VDC to 125.0A at 24.0VDC.

•Power (One Rectifier Module): 2500W or 3000W at Vout ≥24VDC.

•Output Characteristics: The relationship between output voltage and current is depicted graphically in

the following illustrations.

Vertiv |NetSure Rectifier Module User Manual (UM1R243000 / 11BJ1307WA)|Rev. G

•Power Derating Based on Input Voltage:The rectifier can provide maximum rated power (2500W or

3000W) as long as the input voltage is within the range of 180 to 275 VAC. From 180 VAC to 90 VAC,

the rectifier will continue to operate, but maximum power is reduced. The relationship between the

output power and input voltage is illustrated below.

•Power Derating Based on Temperature:Each rectifier continuously monitors the ambient temperature

surrounding the power conversion circuit. If this temperature for any reason (such as a high ambient

temperature or failed fan) 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 +65°C (149°F) will

result in the output power being decreased linearly to 80% of full rated power at +65°C (149°F). Full

power capability is restored when the temperature decreases to below approximately +50°C (+122°F).

Refer to the following curve illustrating typical operating parameters.

Vertiv |NetSure Rectifier Module User Manual (UM1R243000 / 11BJ1307WA)|Rev. G

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 +65°C (+149°F) will result in output power decrease. Operation

above +65°C (+149°F) is considered abnormal and should be used on a temporary1basis only.

1Temporary 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 ±0.5% 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 improved regulation.

b) Dynamic Load: For any step load change within the range of 10% to 90% of full load within 50

microseconds, per Telcordia GR-947-CORE, the maximum voltage transient will not exceed ±5% of

the initial steady state voltage within 250 microseconds. Recovery to within 1% of the initial steady

state voltage does not exceed 4 milliseconds.

c) Dynamic Line: Any step change of line voltage within the specified operating range shall not cause

the output voltage to deviate outside the ±0.5% regulation band.

•Filtering (with or without battery): Typical readings were taken at nominal input voltage, nominal output

voltage, 50% load, and 25°C (77°F) ambient.

a) Voice Band Noise: Complies with Telcordia GR-947-CORE.

1. Typically 30 dBrn with C-message weighting. Does not exceed 32 dBrn C.

2. Typically 0.6 millivolt psophometric. Does not exceed 1 millivolt psophometric.

b) Wide Band Noise: Complies with Telcordia GR-947-CORE.

1. Typically 80 millivolts peak-to-peak. Does not exceed 250 millivolts peak-to-peak.

2. Typically 6.3 millivolts rms. Does not exceed 50 millivolts rms.

AC Input Ratings

•Voltage:

a) Normal: Nominal 208-240 volts AC, single phase, 50/60 Hz, with an operating range of 180 to 264

volts. Acceptable input frequency range is 47 to 65 Hz.

b) Reduced Output: The rectifier operates and provides reduced output power from 180 to 90 volts.

c) Extended: The rectifier operates safely to 275 volts AC.

d) Safe Voltage: The rectifier tolerates 300 volts AC without damage.

•Harmonic Content: Meets EN 61000-3-2.

•Inrush Current: Peak does not exceed 2 times the RMS input current at full load, nominal input voltage,

and for any duration of AC input interrupts. Under the above conditions, standard AC distribution circuit

breakers will not trip.
