  APPLICATIONS INFORMATION
  1. Rated 15A with convection cooling.
  2. Rated 27A with convection cooling. 
  3. Total power must not exceed 135 watts with convection cooling  on open frame models except where noted.
  4. Total power must not exceed 185 watts with 300 LMF forced air cooling  on open frame models.
  5. Total power must not exceed 110 watts with with convection cooling and chassis/cover option.
  6. Total power must not exceed 185 watts with 300 LMF forced air cooling  and chassis/cover option.
  7. Total current from Outputs 3 & 4 must not exceed 3 amps with convection cooling.
  8. Total current from Outputs 1 & 2 must not exceed 20 amps with convection cooling.
  9. Semiconductor case temperature must not exceed 110o C.
  10. Each output can deliver its rated current but total output power must not exceed maximum power as determined by the cooling method state above.
  11. Sufficient area must be provided around convection cooled power supplies to allow natural movement of air develop.
  12. 300 linear feet per minute of airflow must be maintained one inch above any point of the heatsink in the direction shown when forced air cooling is required.
  13. This product is intended for use as a professionally installed component within information technology and medical equipment.
  14. A minimum load of 10% is required on output one to insure proper regulation of remaining outputs.
  15. Remote sense terminals may be used to compensate for cable losses up to 250mV. The use of a twisted pair is recommended as well as a decoupling capacitor (0.1 0 10F) and a capacitor of 100F/amp connected across the load. 
  16. Peak to peak output ripple and noise is measured directly at the output
    terminals of the power supply, without the use of the probe ground lead or retractable tip, 20 MHz bandwidth.
 
  1. This product was type tested and safety certificated using the the dielectric strength test voltages listed in Table V of UL 60601-1. In consideration of clause 20.4g, care must be taken to insure the voltage applied to a reinforced insulation does not over stress basic insulation. Secondary to ground capacitors may need to be removed prior to performing a dielectric strength type test on the end product. It is highly recommended that the DC test voltages listed in DVB.1. Annex DVB are not exceeded during a production-line dielectric strength test of the assembled end product. Please consult factory for further information.
  2. This power supply has been safety approved and final tested using a DC
    dielectric strength test. Please consult factory before performing AC dielectric strength test.
  3. Maximum screw penetration into bottom chassis mounting holes is .100 inches.
  4. Maximum screw penetration into side chassis mounting holes is .250 inches.
  5. To meet emissions specifications, all four mounting hole ground pads must
    be electrically connected to a common metal chassis. Chassis/cover option recommended.
  6. This product is use only one fuse in the input circuit. In consideration of clause 57.6 of UL 2601-1, a second fuse may be required in the end product.
