MULTI-MODE MAINS MODULE ZAX27A BURST FIRED OR PHASE ANGLE X10646 INTRODUCTION The ZAX27A provides accurate and precise mains control in both burst fire or phase angle control modes of operation. This printed circuit board firing circuit is capable of driving an external triac or thyristor pair power devices for any load rating. Additional features also include an uncommitted op-amp, which may be used as an error amplifier or comparator for or closed loop (feedback) control, APPLICATIONS Virtually all resistance heaters including ovens, electric furnaces, moulders, dryers, smelters, heating tapes, stress relieving, space heating and heating mantles. This is unsuitable for use on inductive loads. MAIN FEATURES Dual mode control capability. (phase angle OR burst fire) Soft start delay function Output overload & temperature protection Current limit Microprocessor control compatibility 5KV input and supply isolation Suitable for slave firing triacs or SCR pairs INSTALLATION Connections Shown For Manual Control L N 1 0V 12 HS FUSE 5V DC SW1 ZAX 27A 10K 5K POT T2 10 L O A D 13 0V MODE SELECTION G 9 T1 8 SW1 (ON) = Phase Angle SW1 (OFF) = Burst Fire WARNING 1. This unit requires fusing. This should be a fast acting semiconductor-type (FF5A) fuse placed in series with the LIVE (240V input) supply lead. 2. All HAZARDOUS LIVE terminals - isolate supply before commencing any installation work.
