ASIABLB3004 belongs to Schneider Phaseo AS-Interface power supply family, specially designed for AS-I bus system. Input voltage range 85–264V AC, 47~63Hz, universal global voltage. Output is stabilized 30V DC, maximum output current 4.8A, total power 144W. It integrates ASI decoupling function, providing both power supply and signal carrier for AS-Interface bus, connecting ASI master, ASI slave modules and field sensors/actuators on the same two-wire cable.

This unit adopts 35mm standard DIN rail cabinet mounting. Front panel equipped with green output status LED and orange input status LED for fast on-site status check and fault diagnosis. Screw terminal blocks support wire size up to 2.5mm² for input, ASI bus and ground wiring. Built-in comprehensive protection functions including overload, short-circuit, overvoltage and undervoltage protection; short-circuit protection supports automatic reset after fault removal.

Protection grade IP20 for cabinet installation, operating temperature 0~50℃ without derating, up to 60℃ with power derating. It meets UL, CSA, TUV safety certification and EMC standards for industrial environments. MTBF reaches 100,000 hours at 40℃, ensuring stable long-term operation.

ASIABLB3004 is discontinued legacy Schneider spare part. Many existing AS-Interface automation production lines still adopt this power supply. When the original unit fails, replacing it with identical ASIABLB3004 can reuse existing DIN rail installation, ASI bus wiring and original ASI network configuration without redesigning the bus system. Technicians mount the power supply, check input voltage and ASI bus signal, verify all ASI slave communication, so the AS-Interface fieldbus control system resumes operation and reduces downtime.

Before shipment, every ASIABLB3004 undergoes comprehensive functional inspection including power-on self-test, output voltage calibration, ASI bus signal test, overload & short-circuit protection simulation and LED indicator check. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, ASI bus troubleshooting and network commissioning. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, ASIABLB3004 is reliable spare AS-Interface dedicated power supply for legacy Schneider Phaseo bus systems. It restores two-wire ASI power and communication transmission, extends service life of automation assets and avoids high-cost whole fieldbus system renovation.
