RB-126 Power Booster DC to DC
(KGS products can only be shipped to U.S. address only.)
(DAI Part# RB126)

	RB series is a pulse width-modulated DC to DC converter that provides regulated +28VDC up to 5.0 AMPS
	Converter transforms an unregulated input from a 12V battery to a regulated +28VDC output in a bootstrap mode
	RB series is primarily intended for use in an aircraft with 12VDC battery system to operate 28VDC equipment (especially during periods when the battery is not charged)

	State of the art design for regulation and positive logic for output over voltage protection
	Output is adjustable to 28 ±2VDC via an internal trim pot
	Designed to meet various applicable portions MIL-STD 704 notice three, 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)
