Analogue dimming 1-10V (HFDa) Luminaires for analogue dimming have their own terminal for a polarised two-wire control cable. Brightness is controlled by a potentiometer or an applied voltage between 1-10V. The control cables must have 230V insulation to the circuit and a cross-section large enough so that there is no significant voltage drop. On a 230V circuit, an on/off light switch is required.Switch dim (HFDd) Luminaires using an impulse switch for dimming are based on a digital control protocol. When putting mains on the digital input the lamps dims up/down every second time, This is not a standardized method of dimming. Different suppliers of ballast/ drivers can therefore not be connected to the same switch since they are using different methods. We recommend to use our HFDd ballast to ensure that the systems are backwards compatible.
