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.
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.
Power Circuit: power Triac with parallel R-C circuit for dv/dt protection and current-clamping 2 millisecond fuse for short-circuit protection.
Control Circuit: R-C network with variable-resistance potentiometer adjusts firing capacitor into bilateral diode connected to power Triac gate for stable, full-range control.
Output Voltage: 0-95% of input. Overall Efficiency: 99%.
Power Loss: approximately 1.5 watts/amp.
Voltage Drop Across Power Circuit at 100% Output: 1-2 volts maximum/phase.
Control Input: manual control via variable potentiometer.
Fuse Protection: 2 millisecond I 2t fuses are factory tested and coordinated with all power semiconductors, considering:
a. fuse element melt time tmelt;
b. peak melt current Imelt;
c. arc quench time tarc;
d. peak arc current Iarc.
Ambient Temperature Range: -10 to +500C.
Terminal Connections: Bakelite or thermoplastic blocks.
