BM3 | 3-Phase Burst Fire Trigger Module | MONO-LINK™ 440V AC

Description BM3 3-Phase Burst Fire Trigger Module (MONO-LINK™) The BM3 3-Phase Burst Fire Trigger Module is designed for precise and reliable control of resistive heating loads in industrial and commercial environments. Using advanced MONO-LINK™ gate-to-gate firing technology, the module eliminates phase timing issues commonly associated with multi-phase power control, ensuring stable and consistent operation. With zero-voltage switching, the BM3 minimises electrical noise and eliminates radio frequency interference (RFI), making it ideal for sensitive environments. Its proportional burst-fire operation delivers accurate power regulation based on manual or DC input signals, providing smooth and efficient heater control across a wide range of applications. Key Features Fires triacs or thyristors up to 440VAC MONO-LINK™ gate-to-gate firing for synchronised operation Zero-voltage switching for RFI-free performance Opto-isolated output for safe and reliable triggering Status LED for quick visual diagnostics Proportional burst-fire control via manual or DC signal Benefits Stable three-phase heater control without phase timing issues Reduced electrical interference and improved system reliability Precise proportional power control Simple integration into heating and ventilation systems Safe operation with isolated trigger outputs Typical Applications Air curtains Space heaters Industrial furnaces Ovens and drying equipment General resistive heating systems Technical Specifications Control & Signal Signal span minimum: 0–2V DC Signal span maximum: 0–25V DC Signal zero offset: 0–30% of span Cycle time base: nominal 1 second Manual potentiometer: 2kΩ, 5kΩ or 10kΩ Electrical Ratings Maximum gate/line voltage: 440V AC dv/dt rating: 100V/µs Trigger output rating: 0.8A Trigger isolation voltage: 2500V RMS AC input supply: 18–24V AC/DC @ 65mA Auxiliary output: 5V DC @ 5mA (protected) Line frequency: 50/60Hz Protection & Indicators Opto-isolated trigger output Status LED indicator MONO-LINK fuse: F100mA (HRC) Environmental Storage temperature: −20°C to 85°C Maximum ambient operating temperature: 65°C Connections Power connections: 6.3mm AMP tags
