292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: sales@micropowerdirect.com www.micropowerdirect.com Notes: 1. Start up time is measured at nominal input and with a constant resistive load. 2. Cross regulation is measured with the output being tested at 100% load. The second output is varied from 25% to 100% load. 3. When measuring output ripple, it is recommended that an external 1 µF capacitor and 10 µF capacitor be connected in parallel from the +V OUT to the -VOUT pins for single output units and from each output to common for dual output units. 4. Transient recovery is measured to within a 1% error band for a load step change of 25%. 5. Short circuit protection is provided by a “hiccup mode” circuit. 6. The switching frequency for 24 VDC output models is 285 kHz. 7. Operation at no-load will not damage these units. However, they may not meet all specifi cations if operated below the specifi ed minimum load. 8. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the correct rating. On single output units, an external resister may be added to adjust the converter output. To adjust the output UP , connect a 5%, 3W resistor between the minus output pin (5) and the Vout trim pin (6). To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin (4) and the Vout trim pin (6). The trim table at right gives suggested resistor values for this adjustment.
