The EMCO Q Series 5-kV High-voltage DC/DC converter  is several times smaller than other 5kV supplies, the converter measures just 0.5 (L) x 0.5 (W) x 0.5H in and weights 0.15oz. In addition, the DC/DC converter sacrifices no performance as it exhibits an output ripple of 0.05% - half that of many larger converters.

The converter makes extensive use of surface-mount components to achieve the dramatic size and weight savings. Previously, high-voltage DC/DC converters have been too large and bulky for an emerging generation of portable battery-powered products such as field-emissive flat-panel displays and small scientific instruments. The Q Series overcomes those limitations.

Two version of the supply are available from Powerbox – Q50 with positive output polarity and the Model Q50N with negative output polarity. Both versions need no external components and have no minimum loading requirements.

Specifications include an input voltage of 0 to 5 Vdc, an output power of 0.5W (1.25 W optional), a turn-on voltage of 0.7 V, an isolation voltage of 500V and an operating temperature range of 10o  to 70 o  C.  The converter comes in an encapsulated glass-filled epoxy package.
