The Smartrise Battery Lowering Device (BLD) eliminates the risk of trapped passengers during a power loss situation. Automatically turning on whenever needed, Smartrise's BLD takes over and moves the car to the nearest floor, then opens the door to let passengers exit. Smartrise's BLD outputs sinewave AC, unlike competitors who use semi-sinewave. This makes Smartrise's BLD more efficient and causes less electromagnetic noise.
