The LiftMaster K41-0391-000 EMI Board is a critical power-filtering component designed specifically for the latest generation of MAXUM DC commercial operators. By acting as a specialized shield, this board provides high-efficiency Electromagnetic Interference (EMI) filtering that cleans incoming electrical signals. This protection is vital for maintaining the performance of sensitive logic circuits, as it prevents electrical noise and surges from causing operational errors or hardware damage.
Engineering for versatility and ease of use, this board is a universal fit for the entire MAXUM 700, 1200, and 2200 series, supporting JDC, JHDC, TDC, and RJDC models. It is tailored for 120V and 240V single-phase power configurations and features a convenient plug-and-play design. Each kit comes complete with the EMI circuit board and integrated mounting standoffs, allowing for a secure and rapid installation that minimizes equipment downtime during service.
