Zero Crossing Fired SCR Power Controllers Datasheets

Single-Phase Thyristor Regulators -- JB Series
from CHINO Works America Inc.

The JB series small and lightweight thyristor regulators for single-phase loads are characterized with high panel installation density. 6-models from 10A rated current to 100A rated current are available. Two control systems, a phase-angle firing system and a zero-cross firing system, are built. [See More]

  • SCR Control: Phase Angle; Zero Crossing
  • Phase: Single Phase
  • Operating Voltage: 100 to 240 VAC
  • Maximum Current: 100
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]
