1.0 SCOPE AlidyNE ENOINEl!IIINO CORPORATION ACCEPTANCE TEST PROCEDURE NO. 451 PS294-Q2 This document defines the Acceptance Test Procedure (ATP) for the PS294-Q2 power supply board assembly. Either the end item ATP or a special test procedure appropriate to a p~rticular contract will define any additional requirements.

2.0 EQUIPMENT REQUIRED Table One lists the test equipment required to perform the ATP.

3.0 PRELIMINARY PROCEDURE Record test results as indicated in Appendix A.

3.1 Refer to Assembly Drawing No. Q9854 and inspect assembly for completeness and accuracy.

Inspect the heat sinks to ensure that they are flush mounted on the transistors Ql, Q3, and Q4.

4.0 INITIAL TEST SET-UP 4.1 Connect PS294-Q2, digital voltmeters (DVM) and oscilloscope to the tester as shown in Figure 1. Set the output of the variac to the lowest dial setting and connect to the tester.

Make sure Sl and S2 are in "OFF" position, S3 in"OPERATE" position and S4, SS and S6 are in "OUT" posi-tion.

4.2 Plug in the variac to 115V AC.

Set S7 switch to "AC" position *. Slowly increase the variac output to llSV AC.

The "POWER AVAILABLE" light emit-ting-diode (LED) on tester should be "ON", if not then tester fuse is open.

5.0 FUNCTIONAL TESTS 5.1 LOAD REGULATION Set switch Sl to Position 1.

The DVM should read 5.00 +/-0.25 VDC (no load regulated voltage). Adjust the +5 load to 8,5 ohm.

Set switch S4 to"IN" position. Note the DVM reading (full load regulated voltage).

The differ~

ence between the full load and no load voltage should be less than or equal to 50mV.

Turn switch S4 to"OUT" position.

5.2 Set switch Sl to Position 2.

DVM should read 15.00 +/-0.75 VDC (no load regulated voltage).

Adjust +15 load to 85 ohm.

Set switch S5 to"IN" position. Note the DVM reading again (full load regulated voltage).

The difference between full load and no load voltage should be less than or equal to 150mV.

Set switch, S5 to"OUT".position.

5.3 Set switch Sl to position 3.

DVM should read -15.00 +/-.75 VDC (no load regulated voltage). Adjust -15 load to 85 ohm.

Set switch, S6 to"IN" position. Note the DVM reading (full load regulated voltage).

The difference between no load and full load voltage should be less than or equal to 150mV.

Set switch, S6 to 110UT11 position.

6.0 OUTPUT FAULT 6.1 Set switches*S4, S5 and S6 to"IN" position.

Set switch, S2 to position 2.

Green LED will flash periodically.

Set switch, S2 to"OFF" position.

Green LED will remain on.

6.2 Leave S4, S5 and S6 on"IN" position. Set switch, S2 to position 31 Green LED will be flashing. Set switch, S2 to"OFF" position Green LED will remain on.

7.0 OUTPUT SHORT 7.1 Set switch S2 to. "OFF" position, S4, S5 and S6 to"OUT" position. Sl to "OFF", S3 to Short. Set scope for D.C. coupling.

Sl to position 1. Out-put voltage pulse should_ be 80 +/-20 mSec,.o.so +/-.2 VP-P. (Volts peak to peak).

7.2 Set Sl to position 2.

Output voltage pulse should be 60 +/-20mSec &.25.:t...05 VP-R 7.3 Set Sl to position 3. Output voltage pulse should be 80 +/-20 mSec and

-.25.:!:.*05 VP-P.

Set S3 to operate.

Set +5V load to 8.5 ohm, +15V load to 85 ohm and -15V load to 85 ohm *.

8.2 Decrease AC voltage down to 103.5V and increase up to 126.5V.

+SV output change should be less than or equal to 25mV DC.

8.3 Set Sl to position 2.

Decrease AC voltage down to 103.5 VAC.

+15V output*

change should be less than or equal to 75mV DC.

8.4 Set Sl to position 3.

Increase AC voltage to 126.5.

-15V output change should be less than or equal to 75mV DC.
