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 available output power is a constant 4000 W, 3500 W, or 3200 W (depending on rectifier model). Within these ranges, the rectifiers 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 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 4000 W, 3500 W, or 3200 W (depending on rectifier model).

• Constant Power Mode: As load increases above approximately 4000 W, 3500 W, or 3200 W (depending

on rectifier model) (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.

• 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 (4000 W, 3500 W, or 3200 W) as long as the input voltage is within the range of 176 VAC to 290 VAC (R48-3200, R48-3200e) or 176 VAC to 305 VAC (R48-3500e) or 185 VAC to 305 VAC (R48-4000e). Below 176 VAC (R48-3200, R48-3200e, R48-3500e) or 185 VAC (R48-4000e), and down to 85 VAC, the rectifier will continue to operate normally but will be in a power derating mode.

a) R48-4000e (1R484000e): See Figure 5.

b) R48-3500e (1R483500e): See Figure 6.

c) R48-3200e (1R483200e): See Figure 7.

a) R48-3200 (1R483200): See Figure 8.

• 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 or failed fan) 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 °F) and +75 °C (+158 °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 9, Figure 10, Figure 11, and Figure 12 to view the relationship between the output power and the ambient temperature.

a) Rectifier 1R484000e provides a minimum of 3200 watts at 65 °C and from 48.0 VDC to 58.0 VDC.

b) Rectifier 1R483500e provides a minimum of 2700 watts at 65 °C and from 48.0 VDC to 58.0 VDC.

c) Rectifiers 1R483200 and 1R483200e provide a minimum of 2320 watts at 65 °C and from 48.0 VDC

to 58.0 VDC.

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

Operation between +45 °C (+113 °F) and +75 °C (158 °F) will result in output power decrease. Operation

above +75 °C (+158 °F) is considered abnormal and should be used on a temporary

• Input Protection:

a) Fuse: On the input, two UL recognized fuses are used, not user-replaceable.

b) Input Voltage Protection: Derating from 85 VAC to 176 VAC (R48-3200, R48-3200e, R48-3500e) or

85 VAC to 185 VAC (R48-4000e). Withstand 415 VAC input without damage.

1. The rectifier will shut down at low or high voltage input; low voltage disable point: 80 V ±3 V;

Hysteresis at least 15 VAC for restart. High voltage disable point: 295 V ±5 V for R48-3200 and R48-3200e, 310 V ±5 V for R48-3500e and R48-4000e; Hysteresis at least 10 VAC for restart.

2. Between 85 VAC to 176 VAC (R48-3200, R48-3200e, R48-3500e) or 85 VAC to 185 VAC

(R48-4000e) the output power will be derated linearly according to input voltage per Figure 5, Figure 6, Figure 7, and Figure 8.

3. Over Voltage Isolation: The rectifier will be disconnected from the AC input when a preset non-

adjustable value is reached.

• AC Fail Alarm: The rectifier issues an "AC Fail Alarm" when AC input voltage drops below 164 VAC. This

alarm clears when AC input voltage recovers above 169 VAC. This level can be set by the controller.

• Output Protection:

a) Overload / Reverse Current: An output fuse is provided on each rectifier. This fuse is not customer

replaceable. The rectifier can be plugged into or pulled out of a shelf while operating, without damage or opening the fuse.

b) Current Limiting: The maximum current delivered by the rectifier can be set via the controller from

10 % to 121 % of its rating at maximum rated output voltage. Output Current Limit Error: ≤ ±1.5 A.

c) High Voltage Shutdown:

1. Adjustable Control: If rectifier output voltage exceeds an adjustable preset value and the

rectifier is delivering more than 10 % of its rated current, the rectifier shuts down. (Adjustable from 56 VDC to 59 VDC via the controller. The restart hysteresis is 0.5 V ±0.2 V.)

The rectifier then restarts and a HVSD restart timer starts (time value configurable via the controller, factory default is 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 or by removing the rectifier, waiting until the LEDs on the rectifier extinguish, then turning power to the rectifier on or reinserting the rectifier). 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.

2. Backup: If rectifier output voltage exceeds 59.5 V ±0.5 V (non-adjustable) and the rectifier is

delivering more than 10 % of its rated current, the rectifier shuts down. The rectifier then restarts and a HVSD restart timer starts (time value configurable via the controller, factory default is 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 or by removing the rectifier, waiting until the LEDs on the rectifier extinguish, then turning power to the rectifier on or re-inserting the rectifier).

Page 21

• Over-Temperature Protection: The rectifier provides over temperature protection by derating output

power and recovers automatically.

• 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 plug-and-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 output voltage will not be affected.

• High Temperature Alarm: Each rectifier continuously monitors the ambient temperature surrounding

the power conversion circuit. If this temperature exceeds a preset non-adjustable value, local and extended rectifier Fail alarms are activated. The alarms will automatically be removed when the ambient temperature surrounding the power conversion circuit decreases to below a preset non-adjustable value.

• Cooling: Each rectifier contains a fan for front-to-back force air-cooling.

a) Fan Fault Protection: The rectifier shuts down and its alarm indicator (red) flashes if the fan fails.

Fan failure is detected and reported to controller. The fans are 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: This rectifier may be connected in parallel with any rectifier of the same polarity and

adjusted to the same output voltage.

• Output Current Walk-In:

a) Normal Start:

1. Start up time, defined as beginning at AC switch on and ending when full output power has

been reached, consists of two time intervals, the delay period and the output voltage rampup period.

2. During the delay period the output voltage will be zero.

3. Start up time (AC on, till full power): ≤ 5 seconds.

4. Output voltage ramp up period, t: 50 ms ≤ t ≤ 150 ms. (10 % to 90 % of full power)

5. The rectifier will not suffer any damage, when subjected to repetitive AC switch on / switch off

operations.

b) Current Walk-In (if enabled via controller):

1. 90 % load in > 8 S, 100 % load in < 124 s.

2. According to Telcordia GR-947-CORE, R3-19.

Page 22

• 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.

- The rectifier default factory output voltage is 53.5 V.

- Once power is applied to the rectifier and the rectifier is recognized by the controller, the output

voltage is updated to the setting programmed into the controller.

- If communications with an SCU+ controller is lost, rectifier output voltage goes to a default value

programmed into the controller (this is a separate programmable parameter from the output voltage setting).

- If communications with an ACU+ or NCU controller is lost, rectifier output voltage goes to the last

communicated float output voltage setting in the controller (the last communicated float output voltage setting is stored in the rectifier).

- The rectifier will revert to normal operation once normal communication to the controller is restored.

• Rectifier Output Current Imbalance:

a) When the average current of all rectifier modules is greater than 20 % of full rated current, and the

difference between local rectifier current and average current is greater than 16 % of full rated current, the yellow protection indicator will illuminate.

b) When the average current of all rectifier modules is greater than 10 % of full rated current, and local

rectifier current is less than 1.5 % of full rated current, then the red fault indicator will illuminate.

• Monitoring Function: The rectifier has a built-in advanced DSP that monitors and controls the operation

of the rectifier. The DSP also communicates with the controller in real time through the CAN bus. Table 1 lists the different commands and information exchanged between the rectifier and the controller.

• External Control Circuits: Provided via the associated controller. Refer to the separate Power System

documentation for a complete description of available external control circuits.

• External Alarm Circuits: Provided via the associated controller. Refer to the separate Power System

documentation for a description of available external alarms.

Installing Rectifiers

The rectifier is hot swappable. It can be installed with the system operating.

CAUTION! This rectifier module contains Double pole fusing; parts of the equipment that remain

energized might represent a hazard during servicing after operation of the fuse. If the rectifiers are connected to a 3-phase system, the neutral line should also have a fuse.

WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position

when installing or removing a module. NEVER hold the handle in the closed position when installing a module into a shelf.

Procedure

NOTE!

Refer to

Figure 16

as this procedure is performed.

1. Place the rectifier into an unoccupied mounting slot without sliding it in completely.

2. Click the rectifier handle in order to pop it forward out of the rectifier's front panel (this will also retract

the latch mechanism located on the underside of the rectifier). Refer to Figure 16 for latch mechanism illustration.

3. Push the rectifier completely into the shelf.

4. Push the handle into the front panel of the rectifier. This locks the rectifier securely to the shelf.

5. Repeat the above steps for each rectifier being installed in the system.

6. After the rectifiers are physically installed in the mounting shelf(s), they are ready for operation

immediately after power is supplied to them.

7. Certain functions (i.e. rectifier current limit, rectifier addressing) may require adjustment when adding or

replacing a rectifier Module. Refer to the Power System documentation for instructions.

Replacement Procedures

Rectifier Replacement

The rectifier is hot swappable. It can be removed and installed with the system operating.

NOTE!

Each rectifier locks into a module mounting shelf by means of a latch located on the bottom of

the module. The latch and rectifier handle are interactive. Pushing the handle up into the module’s front panel causes the latch to extend to the locking position; pulling the handle down out from the module’s front panel causes the latch to retract. See

Figure 16

DANGER! Take care when removing a rectifier that was in operation, as rectifier surfaces could be very

hot.

WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position

when installing or removing a module. NEVER hold the handle in the closed position when installing a module into a shelf.

these alarms. If these alarms cannot be easily disabled, notify the appropriate personnel to disregard any alarms associated with this system while this procedure is performed.

2. On the rectifier to be removed, click the rectifier’s handle in order to pop it forward out of the rectifier's

front panel. This will retract the latch mechanism located on the underside of the rectifier and thus unlock the rectifier from the shelf. Refer to Figure 16 for latch mechanism illustration.

3. Slide the rectifier out by pulling forward.

4. Place the replacement rectifier into the mounting slot without sliding it in completely.

5. On the replacement rectifier, click the rectifier’s handle in order to pop it forward out of the rectifier's

front panel (this will also retract the latch mechanism located on the underside of the rectifier).

6. Push the rectifier completely into the shelf.

7. Push the handle into the front panel of the rectifier. This locks the rectifier securely to the shelf.

8. Certain functions (i.e. rectifier current limit, rectifier addressing) may require adjustment when adding or

replacing a rectifier Module. Refer to the Power System documentation for instructions.

9. After the rectifiers are physically installed in the mounting shelf(s), they are ready for operation

immediately after power is supplied to them. Verify that the rectifiers are operating normally.

10. Enable the external alarms, or notify appropriate personnel that this procedure is finished.

11. Ensure that there are no local or remote alarms active on the system.

Rectifier Fan Replacement

Each rectifier uses a fan (P/N 32010086 for 1R483200 rectifier module. P/N 32010109 for 1R483200e, 1R483500e, and 1R484000e rectifier module) for cooling. If fan replacement should become necessary, perform the following procedure.

CAUTION! In a system with NO redundant rectifier, battery must have sufficient reserve to power the

load(s) while the rectifier is removed for fan replacement.

NOTE!

When performing any step in this procedure that requires removal of existing hardware, retain all

hardware for use in subsequent steps.

Procedure

NOTE!

Refer to

Figure 17

as this procedure is performed.

1. Performing this procedure may activate external alarms. Do one of the following. If possible, disable

these alarms. If these alarms cannot be easily disabled, notify the appropriate personnel to disregard any alarms associated with this system while this procedure is performed.

2. Remove the rectifier from the shelf. Refer to a previous procedure for step-by-step instructions.

3. Place the rectifier on a static-safe work surface. Connect an approved grounding strap to your wrist for

the remainder of this procedure.

4. On this rectifier, loosen the three (3) screws on the rectifier front cover and remove the cover.

5. For proper orientation of the new fan, observe the location of the fan wires and the air flow arrows on the

old fan.

6. Unplug the power cable of the old fan and remove the fan.

7. Plug the power cable of the new fan and place the new fan in the space vacated by the old fan. Ensure

the fan wires and air flow arrows match the orientation of the old fan.

8. Position the rectifier front cover back into place and secure with the screws previously removed.

9. Replace the rectifier into the shelf. Refer to the previous procedure for step-by-step instructions.

10. When the fans start, check to ensure that each is providing front-to-back airflow. If air direction is

wrong, immediately remove the rectifier from the shelf. Repeat previous steps to check fan orientation, and correct as necessary. Reinstall the rectifier and again check for proper airflow.

11. Enable the external alarms, or notify appropriate personnel that this procedure is finished.

12. Ensure that there are no local or remote alarms active on the system.
