United Automation DMFC36, Driver Module

Multi Mode, Phase-Angle & Single/Dual Cycle Burst Firing Circuit, DMFC-36

The DMFC-36 module has been designed to offer Phase-Angle or Burst Fire Control in firing a thyristor assembly or complete thyristor controller for driving resistive loads. In Single-Cycle or Dual-Cycle mode, these modules use the fastest burst rates possible, providing very accurate control and minimising Harmonic distortion & Flicker within the system.

• Isolated Pulse transformer outputs
• On Board Protection Fuse

The number of complete mains cycles during fixed repeating periods (typically 1 to 10 seconds) is varied, thus altering the duty cycle or on-/off-time ratio. Trigger pulses coincide with the zero-crossing times of the mains supply thus ensuring no RFI is produced when using resistive loads.
