Vestaboard is an electro-mechanical split-flap display board powered by a single standard 3-prong plug. It does not need to be on a separate circuit breaker.
When changing messages, it will pull similar power to an LCD television but when idle, will use 90+% less power. Power consumption is very low when Vestaboard is not changing messages.
Vestaboard supports 100-240V for US and International power consumption and requires 121-watts when updating messages.
