ALDP109W is a slim LD-P relay designed for power switching applications requiring a 9V DC coil voltage. It features a 1 Form A contact arrangement with a nominal switching capacity of 5A at 277V AC and 3A at 30V DC, making it suitable for high-voltage AC applications. The relay has a compact form factor measuring 20.5 mm (L) × 7.2 mm (W) × 15.3 mm (H), with excellent heat resistance and tracking performance per EN60695 standards. It operates reliably across an ambient temperature range of -40°C to +85°C and is sealed for protection against environmental contaminants. The ALDP109W is ideal for appliances such as boilers, air conditioners, refrigerators, hot water units, microwave ovens, and fan heaters, and is certified by UL/C-UL and VDE for safety compliance.
