Notes: 1. Output regulation includes line & load. 2. Ripple & noise is measured from 10 Hz to 20 MHz. Connection to the unit is made with a 0.1 µF ceramic capacitor & a 22 µF electrolytic capacitor connected in parallel. 3. A 1% minimum load is required to maintain regulation & ripple specifi ca- tions. 4. Transient recovery is measured to within a 1% error band for a load step of 50% to 100%. 5. Isolation specifi cations are production HI-Pot tested for 3 seconds. 6. The full output range (see table) is covered in the safety agency certifi ca- tion. Standard models are factory set to the Preset voltage, but may be set to other levels within the range without affecting the agency certifi cation. For more information, contact the factory. 7. Output power is given for the factory preset voltage. All models provide a peak power level of 700W for a maximum duration of 500 µS. For more information, contact the factory. 8. Each unit includes an input fuse (T8A/250V). Since this fuse is not fi eld replaceable, it is recommended that an external fuse of the same size be used on the input of the power supply for protection.
