Gresham Power Electronics
Gresham offers a wide range of high power density open frame AC:DC switch mode power supplies delivering up to 800W of continuous power with from one to four outputs. These power supplies feature 85–264VAC universal input incorporating active power factor correction, making them ideal for use worldwide. The open frame product family are low profile 1U with industry standard 3”x5” or 4”x7” footprints
Optional DC Input models are available for the telecom market.
Wide input range models are available for outdoor/mobile broadcast and lighting for live event staging.
Medical versions available
Built-in “O-Ring” diodes for N+1 redundancy configurations are standard on eFO models and available to order on other models.
Very high efficiency and power density result from the use of advanced component and circuit technologies, such as synchronous rectification, low profile transformer and SMT components.
When required the Gresham range of open frame power supplies can be supplied with enclosures, cooling fans, input and output connectors, cable assemblies and conformal coating.
Non-standard output voltages are available on request.
Applications for Gresham’s open frame power supplies include bulk power front-ends for distributed power architecture (DPA or IBA) in telecom, military COTS, medical, instrumentation and industrial applications.
