Altronix TM250 Compact Enclosure for Mercury and Lenel Access Control Boards

The Altronix TM250 is a compact powder-coated steel enclosure designed to house various combinations of Mercury EP1501 or MR51e access control boards, with or without an Altronix eFlow or Tango power supply/charger. Built from 16 AWG steel for durability, the TM250 accommodates up to two Mercury controller boards and includes space for one 12VDC/4AH backup battery, ensuring continuity of access control operations during power interruptions. Twelve double knockouts (compatible with 0.75" and 1" conduit) provide flexible cable routing options, while the streamlined internal layout simplifies board placement and wire management for faster installation and easier long-term maintenance.
