BM1

Description

BM1 Single Phase Burst Fire Firing Thyristor / Triacs Circuit –

This singular burst-fire BM1 thyristor control module incorporates the unique MONO-LINK™, gate-to-gate, firing feature, which uses BM1 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 with the BM1, as the BM1 opto-isolated output driver stage is self-timing from the associated power device connections. The BM1 Single phase Burst fire Firing circuit burst firing circuit prevents fast changes in current thus inhibiting radio frequency interference.

BM1 Single phase Burst Fire Firing Circuit Applications:

The BM1 circuit is compatible with 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.

BM1 FEATURES:

• The BM1 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.
