When measuring output ripple, it is recommended that an external 3.3 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. 2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. Operation at no-load will not damage these units. 4. An external 220 µF/100V capacitor connected across the input pins is required to meet EN61000-4-4 and EN61000-4-5. 5. Free air convection is typically 20 LFM. The units should not be operated in still air (0 LFM). 6. Dual output units may be connected to provide a 10, 24 or 30 VDC output. To do this, connect the load across the positive (+VOUT) and negative (-VOUT) outputs and float the output common. 7. It is recommended that a fuse be used on the input of a power supply for protection.
