Three Phase (3-leg) SCR Power Controllers Datasheets

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]
