Features
  • RMS and average measurements
  • Single and three phase applications 
  • 50/60HzRMS and average measurements
  • Galvanically isolated DC outputs
  • DIN rail mounted
The Eclipse Series is a family of Din rail mountable standalone AC power transducers. They are ideal for situations in which the characteristics of single and three phase AC power signals must be measured and retransmitted as isolated DC signals, such as in electrical heating applications. The DC output can be used to drive meters, recorders, digital controllers, alarms, computer inputs and process control systems. All units in the series mount directly on a Din “D” rail and offer a simple fit and install procedure. Units are auxiliary powered, some are self-powered.

Current Transducer
The single and three phase current transducer converts an AC current signal into an isolated standard DC signal. Up to 10A direct or 1A or 5A CT inputs are accepted. Average sensing units may be used for sine waves of less than 1% distortion. RMS units measure true RMS, even for phase angle chopped or distorted signals. Self and auxiliary powered units are available.

 Voltage Transducers 
Single and three phase AC voltage inputs up to 500Vac may be converted into an isolated standard DC signal. Average sensing for sine waves and true RMS sensing for use with sine waves or distorted waveforms are available for single phase applications. Three phase RMS (3W and 4W) units are also available. All units are auxiliary powered.

Power Transducers 
The Watt and Var transducers provide an isolated DC output proportional to the true power in watts (VIcosØ) or reactive power in vars (VI sinØ). They may be used in single and three phase 3W or 4W systems with balanced or unbalanced loads. Avail-able in one, two or three element configurations, units are auxiliary powered. All transducers have a ratio of calibrated power to actual power. This ratio is the product of the CT and VT ratios being used, requiring a sizing calculation to be performed when specifying the product for an application.
