In normal use, just 1 second of power is enough to release the electric lock. Always configure your access control panel or intercom system accordingly to avoid overheating or coil damage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What voltage range is compatible with the 1073 universal electric rim lock coil driver?\u003c\/h4\u003e\n\u003cp\u003eA: This coil driver operates on DC 9–14V with a working current of 1.5–3A, making it compatible with most standard access control systems and power supplies used in residential and commercial door security setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Why is a pure copper coil better than a copper-clad aluminum coil in an electric rim lock?\u003c\/h4\u003e\n\u003cp\u003eA: Pure copper offers lower electrical resistance, better thermal conductivity, and greater durability under repeated use compared to copper-clad aluminum. This means more reliable actuation, reduced heat buildup, and a longer service life for your lock module.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the LIHTNE 1073 coil driver compatible with building intercom and access control systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The 1073 is designed as a universal replacement coil driver and is compatible with a wide range of electric rim locks, access control panels, and building intercom systems. Ensure your system's power delay setting does not exceed 3 seconds before installation.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the maximum recommended power-on duration for the LIHTNE 1073 electric rim lock coil driver?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The coil should not be energized for more than 3 seconds at a time.
