Datasheet

INTRODUCTION
The PAC2 module is a 25A, 230V ac phase angle, full wave controller in a compact and easy to
install package. The PAC2 regulator governs the amount of power supplied to the load, by
controlling the phase angle of the ac supply. The low thermal impedance and high electrical
isolation provides the equipment designer with a greater flexibility in a wide variety of applications.
APPLICATIONS
Suitable for most power control applications such as infrared, quartz and ceramic heaters/lighting. It
can also be used on inductive loads such as transformers and ac motors.
FEATURES
• Solid state reliability.
• Surface-mount technology.
• 50 - 250V ac supply range.
• Rugged and compact.
• 25A current capability (with use of additional heatsink)
• Internal snubber - eliminates “nuisance switching”.
