Load regulation is specifi ed for a load change of 0% to 100%. Load regulation for 3.3V output models is ±1.0% max for a load change of 0% to 100%. 2. When measuring cross regulation, the load on one output is varied from 25% to 100% while the other output is held at 100%. 3. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor be placed from the +VOUT pin to the -VOUT pin for single output units and from each output to common for dual output units. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple. 4. To help meet conducted emissions requirements, the Pi fi lter components (C1, & L1) in the diagram below should be used. These components should be mounted as close to the module as possible. To meet the requirements of EN 61000-4-4 and EN 61000-4-5, an external fi lter capacitor (C 2 in the diagram below) is required. 5. Operation at no-load will not damage these units. However, they may not meet all specifi cations. 6. Dual output units may be connected to provide a 24 VDC or 30 VDC output. To do this, connect the load across the positive (+V OUT) and negative (-VOUT) outputs and fl oat the output common. 7. 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. Recommended Input Components
