Voltage measuring apparatus |
摘要 |
<p>Apparatus for measuring voltage across an isolation barrier. The apparatus includes a voltage input and a voltage output and an opto-isolator provided between the voltage input and voltage output. Processing means are provided at the voltage output to measure and/or monitor pulse width. A Circuit arrangement including two transistors and two resistors is provided to allow a substantially constant current to flow through the opto-isolator.</p> |
