  APPLICATIONS INFORMATION
  1. Rated 10A with convection cooling.
  2. Rated 1.5A maximum with convection cooling.
  3. Total power must not exceed 50 watts with convection cooling on open frame models.
  4. Total power must not exceed 70 watts with 300LFM forced air cooling on open frame models.
  5. Total power must not exceed 40 watts with convection cooling and chassis/cover option.
  6. Total power must not exceed 70 watts with 300LFM forced air cooling and chassis/cover option.
  7. Each output can deliver its rated current but total output power must not exceed maximum power as determined by the cooling method state above.
  8. Sufficient area must be provided around convection cooled power supplies to allow natural movement of air develop.
  9. 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.
  10. A minimum load of 10% is required on output one to insure proper regulation of remaining outputs.
  11. 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.
  12. 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.
 
  1. This product is intended for use as a professionally installed component within information technology and medical equipment.
  2. 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 10MicroF) and a capacitor of 100MicroF/amp connected across the load.
  3. 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.
  4. Maximum screw penetration into bottom chassis mounting holes is .100 inches.
  5. Maximum screw penetration into side chassis mounting holes is .250 inches.
  6. To meet emissions specifications, all four mounting hole ground pads must
    be electrically connected to a common metal chassis. Chassis/cover option recommended.
