POWER SHARING

The 3W total power delivery can be taken from either single channel or any combination of all three channels. This allows an enormous amount of flexibility,

especially when combined with the selectable output OV reference. For example, using the option 2 output configuration; -24V at 0.5W, +24V at 1W and +48V at

1.5W power supplies are available from a single TPT device.
