Output voltage electronic regulation
Through a dial on the unit front panel, it is possible to set the necessary output voltage: from 0Vac to 270Vac.
This regulation can also be done through a remote control (o-10V).
The settled voltage is simultaneously visualized on a LCD display.

Selectable output frequency
Through a switch on the unit front panel it is possible to select the output frequency: 50Hz or 60Hz.
his regulation can also be done through a remote control.
Different frequencies are available on request.

IGBT technology
This technology allows high performances and avoids the under load voltage drop typical of the common electromechanical variac.

Unit monitoring

  • LCD Display with V & A output
  • Controls: ON/OFF switch, frequency selector and output voltage regulation dial
  • LED on the unit front panel with unit status signals
  • DB9 remote input: ON/OFF, 50/60Hz, output voltage regulation

Installation and mainjtenance in absolute simplicity

  • modular systems easily integrated in rack cabinets
  • 19" 5 Units rack
  • each unit is equipped with simple connections on the rear panel

Maximum design flexibility
All our unit can be customixed and adapted to all customers requests:

  • different input/output voltages and frequencies
  • customized units: cabinets, particular packaging, and so on.
