1.0	INTRODUCTION

1.1	ADMINISTRATIVE DATA
	Customer:	MARTEK POWER ABBOTT 2727 S. La Cienega Boulevard Los Angeles, CA 90034
	Contact:	Mr. William Standen (213) 202-8820
	P.O. Number:	76605
	Date of Test:	October 31, 1990 through January 3, 1991
	Equipment Under Test (EUT):	AC-DC Power Supply Model AW20 S/5
	Input Voltage:	120Vac, 1-phase, 60Hz
	Specification:	MIL-STD-461C, Part 2; MIL-STD-462 Class A1b Equipment
	Disposition of Specimen:	The EUT is to be picked up by MARTEK POWER ABBOTT personnel

1.2	TEST SUMMARY
	The following is a summary of the EMI tests that were performed:*

	h) Radiated Susceptibility, RS02, Magnetic Induction Fields	Passed
	i) Radiated Susceptibility, E-Field, RS03, 10 kHz to 10 GHz	Passed
	* Both the MIL-STD-461C, Part 2 and Part 4 limits were plotted on the automated measurement plots per request of the customer.

1.3	PURPOSE OF EMI and EMS TESTS

	The purpose of the EMI and EMS tests were to measure levels of conducted and radiated interference emitted from the EUT and to determine the immunity of the EUT to external electromagnetic signals and fields. The test results were compared with the specified limits. The EMI and EMS measurements on this EUT were relatively complex. These tests were performed under the direct guidance of EMACO's Principal Engineers: Mr. David Bernardin, Mr. Al Mills and Mr. Herb Mertel.

1.4	DESCRIPTION OF EQUIPMENT UNDER TEST

	The EUT was an AC to DC power supply with the following specifications:

In:	120Vac, 1-phase, 60 Hz
Out:	+5Vdc/4 A
Output Ripple:	Less than 100 mVp-p at 25 MHz bandwidth

	The power supply has a 9-pin, D-subminiature connector for the power input and output connections. For testing, the 5 Vdc output was connected to 1.25W (25 W) resistive load. The electrical output load was a resistor bank mounted on a metallic heatsink. The EUT was electrically bonded to the ground plane for all tests.

1.5	ENVIRONMENTAL CONDITIONS

	The environment for the EMI tests was as follows:
	a) Temperature: 25� � 5� C b) Relative Humidity: Laboratory Ambient c) Altitude: Laboratory Ambient

1.6	POWER REQUIREMENTS

	The EUT was designed to operate with 115 Vac, 60 Hz, single-phase input power. The measured voltage and current used during testing was 119 Vac and 0.18 A (21.4 W).

1.7	INTERCONNECTIONS

	The interconnections during the EMI tests were as shown in Figure 1.7-1 which also shows the general test setup used during all tests.

1.8	APPLICABLE DOCUMENTS

	The following documents were applicable to the preparation and performance of the EMI tests discussed:
	MIL-STD-461C August 4, 1986	Electromagnetic Emission and Susceptibility Requirements for the Control of Electromagnetic Interference, Class A1b Equipments (Part 2)
