MIW-AH2A1-6-EN-000 - 18 / 11 / 2019
4 - 10
PRODUCT DESCRIPTION
AH2A1-6 are electric heating controllers for single-phase or two-phase electric heating.
They are used as slave devices and need a “master” device - AH2C1-6, AH2C1-6-500,
etc. - to control them. The series utilise time-proportional control: the ratio between
on-time and off-time alters in order to fit the heating requirements. The current is triac-
switched, which minimises wear and tear, while enhanced control accuracy reduces
energy costs.
