Elevator Energy saving system DR series Power capacity:11KW,25KW,37KW Waterproof wall-mounted structure design
The elevator-oriented DR series is the energy feedback device which is designed to feedback the energy that produced by braking and motor speeding adjustment to the mains supply. It can reduce the electric energy consumption when using the dynamic braking; As a result achieving the purpose of energy saving.
This series of products have installed noise filter, it could connect with mains, but it doesn' interfere the mains and the around electric equipments.
Application:
Elevator and Elevator related equipment
Main Features:
High conversion efficiency
Complete fault protection and management function
Voltage and phase tracking automatically, user-friendly
Full noise filtering, no power grid pollution and equipment interference
Waterproof wall-mounted structure design easy for maintenance and installation
Design and manufacture according to the industrial product level, with high reliability
Low-power products use natural cooling system, while high-power products use intelligent forced cooling system
