SCR Power Controllers -- SCR19 and SCR39 Series
from OMEGA Engineering, Inc.

The SCR19 Series Power Controllers are designed to proportion electric power to resistive loads only, such as ovens, furnaces, heat sealers, etc. (NOTE: They are not designed to drive transformers or any inductive load.) The controllers consist of power semi-conductors (SCRs), properly-sized heat... [See More]

  • Current Ratings: 40, 60, & 80 Amps
  • SCR Control: Phase Angle (optional feature); Zero Crossing (optional feature)
  • Command Signal: Analog Current (e.g. 4-20 mA)
PM3000-3PH Thyristor Power Controller
from West Control Solutions

West Control Solutions presents a range of thyristor power controllers which have been designed to switch 3 legs of 3 phase loads. These thyristor units are ideal for 3 phase configuration with neutral connection, normal (Relay S or Relay M) or variable resistive loads and transformer load types... [See More]
