DS-K4H250S - Pro Series Magnetic Lock

The DS-K4H250S is a Pro Series commercial grade magnetic lock manufactured by Hikvision to provide robust physical door locking control for secure access lanes. Fabricated from premium abrasion-proof materials to resist structural wear over high-frequency usage cycles, this electromagnetic lock delivers a formidable holding power capable of resisting up to 272 kg (599.8 lbs) of static linear thrust. The device incorporates an internal voltage-dependent resistor (MOV) to provide integrated surge and spike protection against backward electrical feedback, features a built-in LED indicator to give immediate visual feedback on door lock status, and offers a customizable dual-voltage input setup that runs on either 12 VDC or 24 VDC (defaulting to 12 VDC out of the box).
