Sifam Tinsley THETA 30 Power Transducer - Programmable Active/Reactive/Apparent Power Input w/DCmA/DCV Output w/Display & RS485

Sifam THETA 30 Series*

The Sifam Tinsley THETA 30 is a compact, multi-function panel mount power quality transducer which measures, calculates and displays major electrical parameters of single and three-phase power systems and converts them into a load independent DC Current or a load independent DC Voltage signal proportional to the measured value.

The THETA 30 is a field programmable unit and can be configured by the user with a 1A or 5A current range and a 100-500V voltage range. This unit measures Active Power, Reactive Power, Apparent Power, Phase Angle and Power Factor and will give a 0-1 DCmA, 0-20 DCmA, 4-20 DCmA, or 0-10 DCV output.

The THETA 30 can be ordered with or without a display, with single or dual outputs and with or without RS485 communication.
