Product Overview

The 18TBP-1-5 is a variable-voltage panel/chassis-mount SCR Power Control that incorporates exclusive design features to protect power semiconductor components against damage. 2milli-second 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. It 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 its stated ratings for current, voltage and temperature and have no known MTBF or life expectancy rating.
  • All solid-state construction
  • Short-circuit protection
  • Integral heatsink chassis
  • No thermal derating
