Thanks to a PCB, all unprotected back-of-board variators equipped with a motor may be controlled with a stabilized 0-10 VDC signal, both remotely or locally, by means of a potentiometer.

There are two types of PCBs:
  • Continuous stabilisation ∓ 1%
  • Cheaper but with a wider window: 2-3 %
They are available for test rooms and allow a stable supply of any pre-set voltage to facilitate tests with non-European voltages, from 0 up to a maximum of 280 V (on request).
