This universal DC 12V 4A power supply is designed to work with a wide range of access control hardware, including magnetic locks (maglocks), electric strike locks, and access control panels that require a stable 12V DC power source.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this power supply be used internationally?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. With a universal AC input range of 110–240V at 50–60Hz, this power supply is compatible with electrical outlets in most countries around the world. Simply use the appropriate plug adapter for your region.\u003c\/p\u003e\n\u003ch4\u003eQ: What protection features does this power supply include?\u003c\/h4\u003e\n\u003cp\u003eA: The K80 power supply includes built-in short-circuit and overload protection across all outputs, plus a 0–15 second power output delay lock. It also features high insulation voltage ratings (up to 1500V AC) to help protect connected equipment from electrical faults.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the output voltage trim range and why does it matter?\u003c\/h4\u003e\n\u003cp\u003eA: The output voltage can be adjusted within ±10% to ±15% of the nominal 12V output. This allows you to fine-tune the voltage delivered to your access control hardware, ensuring optimal performance across different devices and system configurations.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this DC 12V 4A power supply compatible with magnetic door locks?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
