- WorkBee Replacement US Plug Power Supply & Emergency Stop for the WorkBee CNC Machine. The power supply is a fully sealed IP65-rated unit, making it completely dust-tight and vacuum-sealed for long-term durability in workshop environments. With a wide input range (100–240V, 50–60Hz), it is compatible with common voltages and frequencies used worldwide, automatically adjusting to the correct setting. Delivering a 24V output at 320W, it provides stable and reliable power to your macine. An integrated Emergency Stop push button is included for added safety. Pre-assembled and tested, it allows you to quickly cut power to the machine if required. The emergency stop connects directly to the controller and includes mounting hardware to secure both the power supply and switch to your workbench. Please note if your router head is powered separately, the emergency stop will not cut its power.
