| NEW Series L Single Output to 25A, 280 Vac DC control Part Number L24D25C L24D25G Description 25A, 280 Vac 25A, 280 Vac Part Number Explanation L 24 D 25 C NOTES 1) Line Voltage (nominal): 24 = 240 Vac 2) Switch Type: D = Zero-cross turn-on 3) Control Range: C = 3.5-15 Vdc, G = 12.5-32 Vdc MECHANICAL SPECIFICATION 1.37 (35.05 ) 1.00 (25.40) FEATURES/BENEFITS * Ultraminiature package * Designed for PC Board Mounting * Optional thermal pad available (see Optional Add-Ons) * Zero-cross turn-on 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 optical isolation to protect control elements from load transients. The Series L also offers excellent thermal performance. APPLICATIONS * On/Off control of medium-power equipment * Interfacing microprocessor controls to AC loads * Heating control * Medical equipment * Test equipment + I N P U T - A TELEDYNE RELAYS L SERIES Solid-State Relay C AC O U T P U T 1.12 (28.32) 0.78 (19.69) WEIGHT: 0.406 oz.
