BM1/2/3
1,2 & 3 PHASE BURST FIRING
TRIGGER MODULE
X10219
INTRODUCTION
This burst fire control module incorporates the unique MONO-LINKä - Gate to Gate firing feature which uses
single path hard firing for each phase thyristor pair, eliminating cathode firing connections. The zero crossing
triggered output has a variable on/off ratio which is proportional to the manual control signal or dc input demand
signal. Phase timing problems are eliminated, as the opto-isolated output driver stage is self timing from the
associated power device connections. The burst firing circuit prevents fast changes in load current thus inhibiting
Radio Frequency Interference.
APPLICATIONS
Virtually all resistive heater loads including air curtains, space heaters, ovens, furnaces, hot plates, extruders,
moulders, boilers, soldering pots and irons, heating tapes, drying and other heating & ventilating applications,
when used in conjunction with auxiliary power devices.
