2 / 2 page Model Selection Guide Mechanical Dimensions Notes: 1. Load regulation is measured for an output change of 20% to 100%. 2. When measuring output ripple, it is recommended that an external 0.33 μF ceramic capacitor be placed from each output to common. For noise sensitive applications, the use of 1.5 μF capacitors will reduce the output ripple. 3. Operation at no-load will not damage these units. However, they may not meet all specifications. 4. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance may affect the stability of the converter. In applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recommended that a low ESR (ESR <1.0Ω at 100 kHz) capacitor be mounted close to the converter. For 5V input units a 2.2 μF is recommended, for 12V input units, a 1.0 μF and for 24V input units a 4.7 μF. 5. The outputs of these units may be connected to provide a 10 VDC, 24 VDC or 30 VDC output. To do this, connect the load across the positive (+Vout) and negative (-Vout) ouputs and float the ouput common. 6. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating.
