DVC 1000-P įtampos keitiklis

Voltage transducer DVC 1000-P

For the electronic measurement of voltage: DC, AC, pulsed..., with galvanic separation between the primary and the secondary circuit.

Features:

  • Bipolar and insulated measurement up to 1500 V
  • Voltage output
  • PCB mount
  • 8 pins
  • 5 V unipolar power supply
 

Advantages:

  • Low consumption and low losses
  • Compact design
