1Introduction

1.1 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 1000 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, 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 1000 W.

•Constant Power Mode: As load increases above approximately 1000 W (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.

1.2.1 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 VDC, positive ground.Output voltage is adjustable from -42 VDC to -58 VDC via the associated

controller.

•Output Power and Current: 1000 W (17.24 A) @ 208 VAC / 240 VAC input and -58 VDC output.

•Output Characteristics: Refer to Figure 1.1 for a graph of 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 (1000 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 1.2.

Figure 1.2 Power Derating Based on Input Voltage

NOTE!

Blue Line:

Linear derating from 85 VAC to 176 VAC;

Green Line:

Keeping constant power from 90 VAC to 132 VAC, the output power is 500W.

•Power Derating Based on Temperature: The rectifier delivers full power when operating at an ambient temperature of +45 °C

(+113 °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 +45 °C (+113 °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 +45 °C (+113 °C) and +75 °C (+167 °F) will result in output

power being decreased. Full power capability is restored when the temperature decreases to below approximately +45 °C

(+113 °F). Refer to Figure 1.3 to view the relationship between the output power and the ambient temperature.

Other power rating values are as follows (refer to Figure 1.3):

a) At an ambient temperature of +55 °C (+131 °F), the power delivered by the rectifier is 1000 W.

b) At an ambient temperature of +65 °C (+149 °F), the power delivered by the rectifier is 825 W.

c) At an ambient temperature of +70 °C (+158 °F), the power delivered by the rectifier is 720 W.

Additional conditions:

When operating in ambient between 65C to 70C the rectifier can provide 825W of power if the AC input voltage is 200VAC to

250VAC and the DC output voltage setting of the rectifier module is 52VDC to 58VVDC. When operating in an ambient between 65C

to 70C the rectifier module will linearly derate to 800W if the AC input is 200VAC to 250Vac and the DC output voltage setting of the

rectifier module is 50VDC to 56VDC.

WARNING! The rectifier is rated for continuous operation at full output power up to +45 °C (+113 °F). Operation between

+45 °C (+113 °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.

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.)

NOTE!

1000 W @ +45 °C (+113 °F) and 176 VAC < Vin < 264 VAC and 50 VDC < Vout < 56 VDC.

•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.

b) Dynamic: Response time ≤200 microseconds and overshot ≤5 % for load changes at 50 % - 25 % - 50 % and 50 % - 75 %

- 50% at rated output voltage and current.

For any step load change within the range of 10 % to 90 % of full load within 50 milliseconds, the maximum voltage

transient will not exceed 5 % of the initial steady state voltage within 50±10 microseconds. Recovery to within 1 % of the

initial steady state voltage does not exceed 1 millisecond.

•Filtering:

a) Voice Band Noise:

1. Output noise is < 38 dBrnC typical at normal input (208 VAC / 240 VAC) and 30 % to 70 % of rated load for more

than one rectifier.

2. Psophometric noise is ≤ 2 mV typical at 30 % to 70 % of rated load for more than one rectifier.

b) Wide Band Noise:

1. Wideband noise emission is < 250 mV peak to peak between 0 Hz –100 MHz, and < 50 mV rms in any 3 kHz band

10 KHz –20 MHz.
