The Schneider Electric ABLM1A12042 is a Modicon Power Supply range modular regulated switch-mode power supply delivering 12 V DC at 4.17 A from a 100-240 V AC single-phase input. Rated 50 W, it clips onto an omega DIN rail in a 53 mm wide housing and carries an internal 3.15 A fuse plus automatic-reset overload and short-circuit protection. A front LED confirms output voltage presence.
The ABLM1A12042's 4.17 A / 50 W rating is the largest 12 V DC output in the ABLM1A modular family, suited to a panel with several 12 V DC devices sharing one rail-mounted supply. Drop to the 2.1 A or 1 A variants in the same range when the 12 V DC load is smaller, since all three share the same mounting footprint and enclosure.
