Specifications:

1. General Character:
The model WSL series power supplies are designed for use in medical, information technology or laboratory  environments. They provide a "universal"  AC input operation, and can supply 0 to approximately 48W of stable DC output power during cycled loading. The continuous loading limit is approximately 36W.

1.1 The model number suffix "M", indicates that a specific model is for use in a medical environment.

1.2 Optional suffix indicates mechanical input configuration:

  N, North American (or NEMA) plug-in
  U, United Kingdom plug-in BS1363
  E, European mainland, CEE7/16
  A, Australian, AS3112
  If blank, then the standard IEC320 inlet is specified.

2. Electrical Specifications:

2.1 Input: 100-250Vac     50/60Hz    
(90-264 Vac, 47-63 Hz is the tested operational range, 100-250 Vac range is marked on product to comply with safety standards.)

2.1.1 Input Fuses:
A current fuse is incorporated in the AC input line, rated at 1.5A, 250V, slo blo type fuse element, 2AG size, configured with integral welded on leads. Available from Littlefuse, part number 230-1.5. Medical grade models have a second fuse in the AC input neutral line as well.

2.1.2 Input Switch:
An optional input switch may be provided if required. A "I" and a "O" will be marked on it, or next to it.

5.3 Electro Magnetic Compatibility:
Meets requirements of European EMC directive and FCC requirements.

5.3.1 Medical:
Meets EMC requirements from EN60601-1-2 (EMC requirements for ElectroMedical Equipment).

5.3.2 Emissions:
Meets level B requirements of FCC 47 CFR part 15 and CISPR11 (EN55011) and CISPR22 (EN55022), EN61000-6-3 (light industrial) and line harmonic emissions EN61000-3-2.

5.3.3 Immunity:
Meets CISPR24 (EN55024), EN61326 and EN61000-6-1.

5.3.4 EMC Responsibility:
It is the responsibility of the OEM customer to verify EMC compliance with his system before marketing the end-use system.
 

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 radiated emissions program works from the premise that the power supply acts 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 an independent lab and Jerome Industries lab common mode current measurements on the cords of reference power supplies.
Using this technique, Jerome Industries has experienced a 98% 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 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.
 

* The Instruction manual must also contain a notice regarding methods of disposal of the equipment at the end it's useful life.

*  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.

*  This product is classified as Class 2 (double insulated), the optional input functional ground is used only for reduction of leakage current available at the output connections.
