Product Overview

The 18TBP-1-15 is a Variable-voltage Power Control provides infinitely variable control of single-phase AC voltage to resistive heating elements. This control is solid-state replacements for variable transformers, mercury relays, saturable core reactors and electromechanical contactors. Power Triacs replace contacts and brushes to control electric power without moving parts, and when operated within their stated ratings for current, voltage and temperature, have no known MTBF or life expectancy rating. Model 18TBP controls are compact, lightweight packages that employ single hole mounting to panels and enclosure doors. It utilizes an electrically isolated heat sink chassis and incorporates exclusive design features to protect power semiconductor components against damage. "2 millisecond" fuses protect against short-circuit damage, an R-C snubber network protects against dv/dt failure and an integral heat sink chassis allows continuous operation in ambient to 50°C with no derating.
  • Power circuit - Power Triac with parallel R-C circuit for dv/dt protection
  • R-C network with variable-resistance potentiometer adjusts firing capacitor into bilateral diode
  • 50/60Hz Mains frequency
  • 99% Overall efficiency
  • Approximately 1.5W/A power loss
  • 1 to 2V Maximum/phase voltage drop (cross power circuit at 100% output)
