Energy feedback technology
Based upon double-PWM controlled highly energy-saving energy feedback technology, it pollute-less-ly feeds back regenerative green electric energy that shall be originally consumed by energy consumption resistance to power grid It then supplies other power equipment. Compared with ordinary VVVF elevator, it averagely saves over 30% of energy It completely satisfies the relevant national electric energy quality standard
LED automatic lighting
