NNNNooootttteeeessss::::
[1] Output voltage @ 0% load.
[2] Output power @ 100% load.
[3] Please refer to the model number structure for additional ordering part numbers and options.
[4] All specifications are typical unless noted. General conditions for Specifications are +25C, Vin=nominal, Vout = nominal (no trim installed), full rated load. Adequate airflow must be
supplied for extended testing under power.
All models are tested and specified with an external 1F, and 10 F paralleled output capacitors and a 220F external input capacitor. All capacitors are low ESR types. Caps are layout
dependent. These capacitors are necessary to accommodate our test equipment and may not be required in your applications. All models are stable and regulate within spec under no-load
conditions.
