The manufacturer recommends a 12V 7Ah sealed lead-acid battery (approximately 151 × 65 × 100 mm). The built-in 1A charger will fully charge a 7Ah battery in about 4 hours.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this power supply run multiple electric locks and access controllers at the same time?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The TA208CK provides up to 5A continuous output (10A peak) at DC 12V — sufficient to power multiple electric locks alongside an RFID reader, fingerprint scanner, or other access control hardware. The active signal input supports simultaneous connection of more than one access controller.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What happens to my access control system if the mains power is interrupted?\u003c\/h4\u003e\n\u003cp\u003eA: With a 12V backup battery connected, the unit switches to battery power in ≤ 10 ms — virtually instantaneous. Your electric locks and access controllers remain fully operational during the outage. The over-discharge protection circuit automatically disconnects the battery if its voltage drops below 9.5V to prevent data loss in connected controllers.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the DC output voltage adjustable, and why would I need to adjust it?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the output is adjustable between 11.5V and 13.5V. Longer cable runs between the power supply and the electric lock can cause a voltage drop. Increasing the output voltage slightly compensates for this drop, ensuring your electric lock operates correctly even over extended wiring distances.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What types of electric locks and access systems are compatible with this power supply?\u003c\/h4\u003e\n\u003cp\u003eA: The relay output supports both Normally Open (NO) and Normally Closed (NC) wiring configurations, making it compatible with virtually any 12V electric lock — including magnetic locks (maglocks), electric strikes, and solenoid bolts. It also works with RFID card readers, fingerprint terminals, keypad controllers, alarm systems, and 12V CCTV cameras.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is a battery included with the Asia-Teco TA208CK access control power supply?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No, the battery and remote control are sold separately.
