G128-809A Power Supply


The G128-809A Power Supply provides a regulated 24VDC output from an AC or DC input supply. It is suitable for powering devices with a combined continuous current of up to 2.9A. This Power Supply uses a high reliability and efficient switching regulator design and is housed in a compact DIN rail mounting enclosure. It can be applied to provide power to control systems with Moog's Direct Drive Valves (D633,D634 series). The G128-809A can operate at higher output currents subject to voltage, duty cycle, and ambient temperatures (see Application Notes).
