Series L Single Output to 25A 280 Vac DC Control Part Number Description L24D25C 25A, 280 Vac L24D25G 25A, 280 Vac L24D40G 40A, 280 Vac Part Number Explanation L 24 D 25 C FEATURES/BENEFITS • Ultraminiature package • Designed for PC Board Mounting • Optional thermal pad available (see Optional Add-Ons) • Zero-cross turn-on NOTES 1) Line Voltage (nominal): 24 = 240 Vac; 48 = 480 Vac 2) Switch Type: D = Zero-cross turn-on; 3) Control Range: C = 3.5-15 Vdc, G= 12.5 - 32 Vdc 4) /R = RoHS Compliant DESCRIPTION The Series L is designed to control medium-power AC loads, while occupying minimal board space. The Series L is an excellent choice for a PCB-mount power switching relay. A thermal pad is available to eliminate thermal grease when mounting it on to a heat sink. The relay provides optiocal isolation to protect control elements from load transients. The Series L also offers excellent thermal performance.
