Indramat Pac 3.5-100-460A-PO-W1-220

The Pac 3.5-100-460A-PO-W1-220 is a legacy servo power supply unit from Indramat PAC series, designed for Rexroth Indramat digital servo drive systems. This Pac 3.5-100-460A-PO-W1-220 accepts 460V three-phase AC input, delivering DC bus power for matching servo controller and amplifier modules. The Pac 3.5-100-460A-PO-W1-220 supplies stable DC link voltage for multiple servo axes, supporting continuous high torque operation for machine tool, press and automation equipment.

This Pac 3.5-100-460A-PO-W1-220 features built-in power monitoring, overvoltage, undervoltage and overcurrent protection circuits to safeguard downstream servo modules. The Pac 3.5-100-460A-PO-W1-220 communicates with the servo control rack via the internal backplane, providing status signals and fault indication for quick diagnosis. The suffix PO-W1-220 defines the power stage configuration, cooling type and optional voltage variant of this unit.

The Pac 3.5-100-460A-PO-W1-220 is widely used on old CNC machine tools, metal forming machinery and transfer lines equipped with Indramat servo systems. The Indramat PAC series has been discontinued for many years. Most available Pac 3.5-100-460A-PO-W1-220 units are tested surplus spare parts for emergency replacement and lifecycle support of legacy Indramat drive cabinets.
