  • Page 5: Introduction

    1. Introduction The Voltage Transducer is a DIN Rail/wall mounted 43.5 X 65.5mm Transducer. The Voltage Transducer is used to measure and convert AC Voltage input into proportional DC current or voltage output signal. Output signal generated is proportional to the True RMS (upto 15th Harmonic) of the input Voltage.

  • Page 52: Emc Installation Requirements

    The Voltage Transducer should be mounted in a reasonably stable ambient temperature and where the operating temperature is within the range 0 to 45 C . Vibration should be kept to a minimum and the product should not be mounted where it will be subjected to excessive direct sunlight.

  • Page 53: Case Dimension

    EMC enclosures that protect against electrical interference which could cause a disturbance in function. 2. Avoid routing leads alongside cables and products that are, or could be, a source of interference. 3. To protect the product against permanent damage, surge transients must be limited to 2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source.
