Description

NTRODUCTION
This burst-fire control module incorporates the unique MONO-LINK™, 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 burstfiring circuit prevents fast changes in 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 and ventilating applications, when used in conjunction with auxiliary power devices.

FEATURES

• Fires triacs or thyristors up to 440V (50/60Hz) supplies
• MONO-LINK™ gate-to-gate firing
• No phase timing or matching required
• Zero voltage switching (RFI free).
• Status LED giving output ratio indication.
