The DEI1030 is designed to improve lighting bus tracking from unit to unit. Bus voltage is converted to a 0-5VDC signal level output that can be used to control analog drive of incandescent bulbs. It can provide the conditioned input to an ADC/microprocessor for pulse-width modulation, or to the control input of a DEI1090 LED Driver to emulate incandescent lamps using LEDô__s. The need for different bus interface devices for each bus voltage is eliminated.
