 Notes:

1) Emissions are monitored on all prototypes using a spectrum analyzer with peak, quasi peak and average mode power measurement capabilities. Conducted emissions are recorded for both 120 Vac and 230 Vac input conditions. A correlated radiated emissions program is used in order to economically verify the radiated emissions from a specific model.
The emissions program works from the premises of the power supply acting as a dipole antenna radiator, one side of the dipole antenna being the input cord, the other side being the output cord. Levels are monitored on the cords by a common mode current sensing device operating into a spectrum analyzer. Correlation factors have been established which are based upon the difference between radiated field measurements made at independent labs and Jerome Industries lab common mode current measurements on the cords of reference power supplies.
Using this technique, Jerome Industries has experienced a 100% passing rate for prototypes submitted for radiated field emissions testing at independent labs.

OEM System Engineer Instructions

*  The EMC characteristics of the final system comprised of both the power supply and the main system must be evaluated to the applicable EMC environment regulations.

*  Should a power supply need repair, please return it along with a note describing the particular problem to:

  Jerome Industries Inc.
  730 Division St.
  Elizabeth, NJ 07201
  U.S.A.

*  Circuit operation block diagrams, isolation diagrams, and a list of safety critical components will be available on request to appropriately qualified personnel.

* All products which contain externally replaceable double input fuses shall contain the following text in the system installation manual: "CAUTION: DOUBLE POLE/NEUTRAL FUSING"

Medical Products

*  When used with medical products the Instruction Manual prepared for the end use product must incorporate at a minimum, the following power supply warning notices:
 

 a) Warning: When cleaning the power unit, use a cloth dampened with cleaning alcohol on the outside   of the enclosure only. Do not immerse product in water or a safety hazard could arise during use.
 b) Warning: Do not use this power unit in the presence of flammable anesthetics.
 

*  Periodic leakage current testing should be done on the combined power supply and end-use system on a yearly basis when used in a hospital environment where such test equipment is commonly available.
