August, 2001 Rev. K Full power is available at the maximum output voltage on either of two voltage ranges. The standard voltage

ranges are 135 and 270. Three optional voltage range pairs are available: 67.5/135, 156/312 and 200/400. All "P" Power systems except for the 6000L will deliver full power from 45 to 2000 Hz. All 6000L-P power systems will

deliver full power from 45 to 440 Hz. The 2750L-3P, 4500L-3P and 6000L-3P will deliver full power from 45 to 5000 Hz. The power sources are illustrated in

Figure 1-1. The 200/400 volt range (EHV Option) is specified for full power from 45 to 1000 Hz. The output frequency of all "P" power systems can be programmed down to 17 Hz at a reduced output voltage.

2.5 OUTPUT CONNECTIONS

The output terminal block, TB1, is located at the rear of the power system. For a single power source power system, all load connections must be made at TB1. The external sense inputs allow the power system output voltages to be monitored directly at the load and must be connected. The external sense wires are connected at J6 on the rear panel. Refer to Figure 2-2 for all connections .

The output power cables must be large enough to prevent a voltage difference greater than 2 VRMS between the voltage at TB1 and the voltage between External Sense HI and LO input. Table 2-1 shows the maximum length of the output wires. The table assumes the External Sense input is connected at the load.

Table 2-1 MAXIMUM LENGTH OF OUTPUT WIRES

MAX LENGTH (ft) = 2/(MAX CURRENT PER PHASE X 0.0027) MAX LENGTH (ft) = 2/(MAX CURRENT PER PHASE X 0.0017) MAX LENGTH (ft) = 2/(MAX CURRENT PER PHASE X 0.00111) MAX LENGTH (ft) = 2/(MAX CURRENT PER PHASE X 0.00061)

Refer to Figure 2-2 for the connections. The 1-phase output for a single power source with the MODE Option is available from TB1, pins 3 and 4.

2.6 OUTPUT VOLTAGE RANGES

The standard voltage ranges for this AC power system are 135 and 270. Selection of the 270 volt range causes the front panel "HIGH RANGE" lamp to illuminate. The range may be changed from either the front panel keypad or through the GPIB input. All voltages are programmed line-to -neutral for 3-phase operation.

2.7 FUNCTION TEST

Refer to Figure 2-3 for the test setup. Perform the following test sequence.

1) Apply the AC line power and turn on the front panel circuit breaker. No loads should be connected to

the output terminal block.

2) Verify that the POWER ON lamp is lit.

August, 2001 Rev. K

3) With the front panel keypad program the HI output voltage range with the following key sequences: 4 ENT To select the Range screen (RNG) To program the HI range (ex., 270 volt range): 270 PRG ENT

4) Verify the HIGH RANGE lamp is lit.

5) Program the output to maximum voltage with the following key sequences: Depress the MON key 1 time to select the Amplitude screen (AMP). To program the voltage to maximum. (Maximum Range value) PRG ENT

6) Verify that the front panel voltmeter indicates approx imately the programmed value for all three phases

or for phase A for a 1-phase system.

7) Program the AC Power System to the low range with the following keystrokes: 4 ENT (low voltage range value) PRG ENT

8) Program the output to the maximum low voltage range voltage: 5 ENT (maximum low voltage range value) PRG ENT

9) Observe each of the outputs with the oscilloscope or distortion analyzer. The outputs should be clean

sine waves having less than 1.0% distortion.

10) Apply full loads to each phase (Refer to Table 4-1). Verify that the voltage of each phase remains

within (0.0005 x voltage range) volts of the no-load voltage. The waveforms shall still appear clean on the oscilloscope and have less than 1% distortion.

11) Program the Current Limit to 5.0 amps: 8 ENT 5 PRG ENT

12) The display should show the error message 'AMP ABC FAULT' for a 3-phase system. The error

message may not, however, include all of the phases. The output will default to a programmed value of 5.0 volts with the output relays open.

2.8 REAR PANEL DIP SWITCH (SW1)

The rear panel Dip Switch is used only for the output phase configuration in high power multi-chassis systems. The following product/system configurations must have the DIP switches set to the logic "1", or OFF position. a.) All single chassis systems

b.) All chassis with the Oscillator/Controller installed. c.) All chassis in systems with the MODE option installed.

SECTION 3 OPERATION

3.1 GENERAL

The AC Power System may be programmed from the front panel or through the IEEE-488 external interface. The rear panel of the AC Power System holds the power input and output terminals external sense connector, system interface connector, IEEE-488 interface connector and the chassis ground stud.

3.2 FRONT PANEL CONTROLS

All front panel controls are shown in Figure 3-1. A voltmeter selector switch is located at the right side of the front panel voltmeter. The three position switch changes the signal applied to the voltmeter from the three output phases.

A three-pole circuit breaker is on the left side of the front panel. The circuit breaker is used to switch power to the unit. When the circuit breaker is switched ON, the amber indicator lamp above the circuit breaker illuminates.

The front panel has a subpanel with a keypad, remote lamp, LCD display and a viewing angle adjustment. The 20-key keypad allows the power source to be manually programmed at the front panel. The knob labeled VIEW ANGLE may be turned to adjust the contrast of the front panel display. The remote lamp illuminates when the AC Power System has been addressed through the IEEE-488 interface (GPIB).

3.3 FRONT PANEL INDICATORS

A lamp is located just above the input circuit breaker. It illuminates when power is applied and the circuit breaker is on. An analog voltmeter, that indicates from 0 to 300 volts, shows the actual voltage of the phase A, B and C outputs. The

phase is determined by a three position toggle switch at the right side of the meter. An OVERTEMP lamp illuminates when the temperature of the power amplifier heatsinks has surpassed a maximum set

level. When the fault is detected, the outputs are disabled and must be reprogrammed after the overtemperature condition has been eliminated.

An OVERLOAD lamp illuminates when the output current exceeds the programmed current limit value. The outputs will default to 0.0 volts and the output relays will open shortly after the condition occurs.
