The HE1AN-Q-DC12V is a TM-type single-side stable DC power relay manufactured by Panasonic with 1 Form A contact arrangement rated for 30A switching capacity. The relay operates on a nominal coil voltage of 12V DC and features excellent resistance to contact welding through pre-tension and kick-off mechanisms, passing TV-15 certification. It delivers high electrical life of 2×105 operations at 20 cycles per minute and mechanical life of 107 operations at 180 cycles per minute for DC type, with surge voltage resistance exceeding 10,000 V between contacts and coil. The relay is UL, CSA, VDE, and TÜV certified, making it suitable for office equipment applications such as copiers and air conditioning systems where reliable high-capacity switching and long operational life are required.
