Presenting an adjustable 24-VDC output voltage, Carlo Gavazzi’s SPD Series 3-phase switch-mode power supplies deliver outputs of 120 W, 240 W, 480 W, and 960 W. The DIN rail-mountable devices exhibit up to 93% efficiency, input voltage ranges from 340 VAC to 575 VAC and 480 VAC to 960 VAC, and power factor correction. Outputs are protected against short circuits, overvoltage, and overload conditions. LEDs provide and annunciate onboard diagnostics and power source “ON”. A power ready output relay signals the presence or lack of proper 24-VDC output power. Parallel connection is standard in all devices except 120 W, and some models offer the option of a 12-VDC or 48-VDC output.
