Paralleled Remote Voltage/Current Adjustments
The simplest way to achieve remote voltage/current programming with paralleled outputs is to operate the modules in share parallel mode. Follow the
procedure outlined earlier to configure the outputs in share parallel mode and once configured in this mode, all the V
CONTROL
and COM pins can be connected
together. Remote voltage/current programming can then be performed exactly as with a stand-alone module.
It is not recommended to use remote voltage/current programming in normal parallel mode.
Paralleling Across Multiple Products
Paralleling across multiple product is not possible without external protection (such as external diodes or controlled MOSFETs) to prevent circulating currents
between each product. Failure to provide such protection may result in damage to the power supplies. Consult Vox Power for details on how best to implement
such applications.
When modules are paralleled across multiple products, the outputs in each product will not be synchronised and the peak to peak output ripple may contain
beat frequencies in the audio spectrum.
WARNING!
Care must be taken to avoid differential voltages between the negative power output terminals of share mode paralleled modules as this can cause errors
at the control pins. To avoid this, it is recommended to use Vox Power parallel links to parallel modules in share mode.
