AHES3191 is a compact 12V DC power relay featuring 2 Form A contacts with a nominal switching capacity of 35A at 277V AC, designed for high-capacity switching in energy management and industrial equipment. The relay measures 30 × 36 × 40 mm and operates at 1,880 mW with a holding power of only 170 mW at 30% of nominal coil voltage, contributing to significant energy savings in equipment. It features AgSnO2 contact material with a maximum contact resistance of 3 mO, a contact gap of 3.2 mm compliant with VDE0126, and reinforced insulation between contacts and coil with a minimum clearance of 11.0 mm. The relay is RoHS compliant, UL/C-UL and VDE certified, and is commonly used in photovoltaic inverters, uninterruptible power supplies (UPS), and industrial control systems where reliable high-current switching and long operational life are required.
