Abstract:
The invention is a motor-driven adjustable height podium having motor control circuitry with up and down relays for directing current through the electric motor to raise or lower the podium. The relay circuitry is specially configured to avoid a short circuit condition should a situation occur in which both the up and down relays are shut at the same time. Up and down limit switches limit the maximum vertical travel of the podium. A protective circuit breaker and isolation switch are also provided. The unit is designed to be powered from a standard 110 volt wall socket, for powering the motor, and a 24 volt power supply, for powering the relays.
