AFM-11 UNIVERSAL PHASE ANGLE X10221 TRIGGER MODULE INTRODUCTION This single phase or phase to phase trigger module uses variable phase angle control with adjustable signal matching, integral current limit input and adjustable soft start. The pulse train output is reliable, powerful and universally applicable to resistive or inductive loads. The power transformer is remote for increased reliability and wide operational voltage capability. Adjustable current limit allows feedback control and via a few external parts, this can also give voltage or speed control of AC or DC loads. The module is fully enclosed for safety and eligibility in industrial environments. APPLICATIONS Applicable to most AC or DC, resistive or inductive loads via thyristor, triac or hybrid diode stacks on single phase to neutral, or phase to phase supplies, within voltage limits. FEATURES Fires triacs or thyristors up to 480V, 50/60 Hz supplies. Adjustable soft start function. Adjustable current limit control. Pulse train firing via isolation transformer. Consumes under 2 watts.

On initial switch on some loads may need an increased factor of safety (F of S) for unit and/or device protection. (See the SRA Datasheet for further information). CE MARKING This product family carries a CE marking. These phase angle controllers need a suitable remote filter. For information see recommendation section and contact our sales desk.
