Schneider Electric ABLS1A24021 Modicon 24V DC 2.1A 1-Phase 100-240V AC Regulated Power Supply

The Schneider Electric ABLS1A24021 is a regulated switch-mode DC power supply from the Modicon Power Supply range, converting a 100-240 V AC single-phase input into a regulated 24 V DC output at up to 2.1 A (50 W). Housed in a compact plastic enclosure for DIN-rail mounting, it protects against overload and short-circuit with automatic restart once the fault clears.

Selection Notes

At 2.1 A / 50 W and a compact plastic enclosure, the ABLS1A24021 is sized for a single small controller or a handful of 24 V sensors and relays rather than a full I/O rack - oversizing the supply here only adds panel footprint. Its 24-28 V adjustment range and automatic-reset overload and short-circuit protection keep a compact 24 V DC rail alive through transient faults without a service call.
