S-250W series normal single switching power supply

WeHo professional 250W Switching CNC Power Supply can be widely used in Industrial Automation and CNC Stepper/Servo System.

115V and 230V can be chosen by switch.

Powerful functions(eg. PWM control) and professional designs (Built-in big fan for cooling) ensure high efficiency and high reliability of the power supply.

Low cost also makes it more acceptable for general usage.

White cap over the connectors for security setting of dust-proof protection for electrical shock

Standardized procedure for testing through all production process

Protections: Short circuit / Overload / Over voltage

Input voltage :90-132/180-264VAC , changed by switch

Withstand 1.5KV surge input for 50 seconds

100% full load burn-in test

Low cost , high realibility

Inner security for using
