Payne Engineering 18TBP Series Variable Voltage Power Control
Model 18TBP controls provide infinitely variable control of single-phase a.c. voltage to resistive heating elements. These controls are 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.
PANEL- OR CHASSIS-MOUNT Model 18TBP controls are compact, lightweight packages that employ single hole mounting to panels and enclosure doors, utilize an electrically isolated heatsink chassis.
Dimensions: 2.5" x 2.5" x 2" Open Chassis Dimensions: 3.2" x 2.5" x 2.5"
EXCLUSIVE ADVANCED TECHNOLOGY: Model 18TBP controls incorporate 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; an integral heatsink chassis allows continuous operation in ambients to 500C with no derating.
