Beckhoff AX8640-0000-0000 Power Supply Module

Beckhoff AX8640-0000-0000 Power supply module is a 40 A DC-link power source for the AX8000 multi-axis servo system, delivering the DC link and 24 V peripheral supply required to power axis modules and optional modules in a dense servo installation. It accepts three-phase mains input (3 x 200–480 VAC) with an integrated mains filter (category C3) and specifies rated input current of 35 A and a maximum input current of 70 A, with a system SCCR of 65 kA. On the DC-link side, it provides a maximum 848 V DC with 625 µF of capacitance and a continuous output current of 40 A, plus a peak current of 80 A for up to 5 seconds. The unit's 24 V system and peripheral voltage are +6%/−10% and it draws about 120 mA for the 24 V rail. External braking resistor requirements depend on the connected load (there is no internal braking resistor). The module dimensions are 90 mm wide, 230 mm high, and 192 mm deep, and it weighs approximately 3.546 kg. In AX8000 configurations, the AX8640 supplies the DC-link to axis modules and option modules, with a permissible sum current for all connected AX modules listed as 20 A. The part number AX8640-0000-0000 identifies the 40 A variant used to establish the AX8000 DC-link for servo drives.
