The LDD family of DC/DC converters is an optimal response to the applications where compactness and high reliability are requested. All are isolated and offer a wide range of input voltages. Simple but elegant look and ease of installation make them ideal for various industrial applications. High efficiency and compact size Wide Input voltage range Isolated topology Overload 150% Excellent reliability Industrial machine control Process control Energy management Remote control systems LDD240 Series 2 LDD240-11024 110 VDC (90 - 148 VDC) 2.6 A - 3.6 A 24 VDC 10 A Technical parameters are typical, measured in laboratory environment at 25C at 110 VDC and nominal values, after minimum 5 minutes of operation.
