Established in 1985, Mastech Power Supply brings three decades success in regulated variable DC power supplies. Our large selection of 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 three 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.
With more than 10 years of experience selling and servicing Mastech Power Supplies directly in US, we are your best source for regulated variable DC Power Supplies. Due to the widespread of copycat products in the market, we only service products bought directly from us, but will be happy to provide technical help even if you may have a knockoff product.
