Model 18TBP/TB controls provide infi-
nitely variable control of single-phase
a.c. voltage to resistive heating ele-
ments. These controls are solid-state
replacements for variable transformers,
mercury relays, saturable core reac-
tors, and electromechanical contactors.
Power Triacs replace contacts and
brushes to control electric power with-
out moving parts, and, when operated
within their stated ratings for current,
voltage, and temperature, have no
known MTBF or life expectancy rating.

TYPICAL APPLICATIONS
Model 18TBP/TB
FEATURES
Model 18TBP controls are compact,
lightweight packages that employ
single hole mounting to panels and
enclosure doors. Model 18TB con-
trols are designed for rear or rack
mounting. Both utilize an electrically
isolated heatsink chassis.
Model 18TBP/TB controls incorpo-
rate exclusive design features to
protect power semiconductor com-
ponents against damage. “2 milli-
second” fuses protect against
short-circuit damage; an R-C snub-
ber network protects against dv/dt
failure; an integral heatsink chassis
allows continuous operation in
ambients to 50
Power Circuit: p ower Triac with par-
allel 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.
Mains Frequency: 5 0/60 Hz.
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 maxi-
mum/phase.
Control Input:manual control via
variable potentiometer.
Control Power: 1 watt.
Fuse Protection:2 millisecond I
fuses are factory tested and coordi-
nated with all power semiconduc-
tors, considering:

Terminal Connections: B akelite or
thermoplastic blocks.
Model 18TBP/TB controls are rated
for use with constant resistance
loads. Size units by actual load cur-
rent, not kW.
1> Always use maximum possible
load current for sizing purposes.
2> The amp rating is determined by
the fuse. Current draw must not ex-
ceed the fuse rating at any time.
3> Rated voltage of connected load
should match control input voltage.
Application: s ingle-phase, 800 watt
nichrome heating element; input
voltage 120 VAC, 60 Hz.
Model Number Selection:
a. Triac-based variable-voltage: SC
b. Panel-mount: E
c. 120 VAC input: 12
d. Amp rating, calculated as follows:
800 = 6.66 amps
120
Since 6.66<10, amp rating: -10
Model Number:SCE12-10.
PERFORMANCE NOTE: Triac
power circuits may “slave” when
multiple units are used on 240 VAC
lines derived from three phase
mains. For optimum performance,
use on single phase, 240 VAC de-
rived from 3-wire, 120/240 VAC
mains.
