Weho S-250W

S-250W series normal single switching power supply

WeHo professional 250W switching CNC power supply can be widely used in industrial automation and CNC servo/stepper systems.
The switch can choose 115V and 230V.
Powerful functions (e.g. PWM control) and professional designs (built-in large fan for cooling) ensure high efficiency and high reliability of power supply.
The low cost also makes it more acceptable for general use.
