  1. Each output can deliver its rated current but total output power must not exceed 28-35 watts depending on model.
  2. Sufficient area must be provided around convection cooled power supplies to allow natural movement of air to develop.
  3. A minimum load of 10% is required on output one to insure proper regulation of remaining outputs.
  4. 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.
  5. Peak to peak output ripple and noise is measured directly across a 1F ceramic capacitor at the output terminals of the power supply cord, without the use of the probe ground lead or retractable tip, 20 MHz bandwidth.
  6. 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.
  7. 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.
