    The RB Series is a pulse width-modulated DC to DC converter that provides regulated +28 VDC up to 5.0 amperes

    The converter transforms an unregulated input from a 12V battery to a regulated +28 VDC output in a bootstrap mode.

    The Model RB Series is primarily intended for use in an aircraft with 12 VDC battery system to operate 28 VDC equipment (especially during periods when the battery is not charged) .


    • State of the art design for regulation and positive logic for output overvoltage protection.
    • Output is adjustable to 28 2 VDC via an internal trim pot.
    • Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202 and MIL-T-5422F class 1A.
    • The Model RB Series is serviceable, small and lightweight (110 watts per pound and 5.8 watts per cubic inch for the RB-126)
