United Automation DMFC36, Thyristor Trigger Module

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.

Includes a Transformer
Standard Din Rail Mount
On Board Indication of Power, Burst-Rates & Fault Conditions
Phase-Angle, or Burst Fire Control
Single-Cycle / Dual Cycle Burst Fire modes of control or adjustable Standard Burst Firing
Soft-start (1 to 30 seconds)
Inhibit Input
Wide Range of Control Options: 0-5V, 0-10V, 1-5V, 2-10V, 0-20mA, 4-20mA, Manual Potentiometer
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.
