High Voltage Power Transformers - General Amp Use

Hammond Manufacturing High Voltage Power Transformers for General Amp Use are available in an expansive range of options and packages, such as open style or enclosed. These transformers offer an overall volt-amps (VA) power rating that ranges from 6VA to 1610VA. The 200 Series offers a 115V/125V primary voltage rating (60Hz only) in an enclosed chassis-mount package with 6" (minimum) long leads. The 261-262 Series features a 115V primary in a cost-effective chassis-mount design and is suitable for small power or bias supplies, test equipment, preamps, and more. The 700 Series has a 115V or 117/234V primary and is available in an enclosed chassis-mount design with 6" (minimum) long leads.
