INTRODUCTION
This single phase firing module with integral 26A triac, uses variable phase angle control with adjustable signal
matching and selectable soft-start. The power supply transformer is remote for increased reliability and wide
operational voltage capabilities. The FC11AL/2 controller governs the amount of power supplied to the load, by
controlling the AC supply. A ramp and pedestal input circuit, allowing variation of firing phase angle by DC
signal, enables more power through to the load with increasing angle.
APPLICATIONS
Suitable for most AC resistive loads with current ratings up to 25A when fitted onto a suitable heatsink (see
cooling requirements). Also some inductive loads such as transformers and full wave vibrators.

AP02/4 COS UAL Conditions of sale
NOTE It is recommended that installation and maintenance of this equipment should be done with reference to
the current edition of the I.E.E wiring regulations (BS7671) by suitably qualified/trained personnel. The
regulations contain important requirements regarding safety of electrical equipment. (For International
standards refer to I.E.C directive IEC 950).
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. (See Declaration of Conformity)
FUSING:
It is recommended to use semiconductor (fast acting) type fuses or circuit breakers (Semiconductor - MCB) for
unit protection and an appropriate fuse for unit supply (F1A). On initial ‘switch on’ some loads may need an
increased Factor of Safety (F of S) for unit and/or device protection. (See SRA Datasheet for further
information).
