There are three series within the i6A range. The i6A operates from a 9 to 40 V input, can deliver up to 14 A, and is adjustable from 3.3 to 24 V. The i6A4W has a wider input range of up to 53 V, a maximum output current of 20 A, and is adjustable from 3.3 to 15 V. The i6AN can deliver negative output voltages of -3.3 to -30 V, accepts a +9 to +40 V input, and has a maximum output current of 8 A. The maximum power limit is 250 W for the i6A and i6A4W and 75 W for the i6AN. Option models are available on i6A and i6A4W models which includes a Power Good signal and allows frequency synchronization and output sequencing.
