Welcome to Mastech Power Supply


Established in 1985, Mastech Power Supply brings three decades success in regulated variable DC power supplies. Our linear DC power supplies offer exceptional noise and ripple performance, and our switching DC power supplies pack superior power and performance into a very small form factor. In the last 10 years, we have significantly improved reliabilty and fault tolerance by adding over-voltage and reverse-voltage protection to most of the updated models under the new brand of Volteq.
