The IFM AC1256 is a single-phase switching power supply optimized for AS-Interface networks, delivering stable 30.5V DC output (NEC Class 2 compliant) with electronic data decoupling to prevent signal interference on the AS-i yellow cable. It features universal AC input (100-120V/200-240V auto-select), high efficiency (86.9-88%), and robust protections including short-circuit, overload, over-temperature, and ground fault detection with LED indicators (green AS-i OK).
Designed for control cabinet mounting with 40mm top/bottom clearance, its narrow 40mm width saves space while convection cooling ensures reliable operation up to 70°C (derating applies). Screw terminals accept up to 4mm² wire, supporting up to 50 slaves with sufficient power reserves for current peaks. Ideal for factory automation, material handling, and distributed I/O systems requiring maintenance-free 24/7 operation.
