The Vext input (connector CN1
– terminals 10 and 11) permits analogical remote control of output
voltage with a programmable variation range of up to ±10% (parameter 16, by default the setting is
±5%) with respect to the value set. If you want to use continuous voltage, it will be effective if it is in
the range between 0V and +2,5V. The input tolerates voltages from
–5V to +5V, but for values
exceeding the limits of 0V / +2,5V (or in the event of disconnection) it is automatically disabled and
the voltage adjustment goes back to the value set through the trimmer (if enabled) or through
parameter 19 (as shown on the picture).
Changing of DSR parameters requires PC with dedicated software and DI1-DSR unit!
DSR automatically detects presence of transformer for parallel operation (if used it works with
droop, if not used it works isochronous).
