Why SITOP PSU8400?

The 3-phase power supplies 20 A and 40 A provide a reliable 24 volts for demanding applications. Robust design, high power reserves and 2-phase operation support stable machine operation.

Convenient parameterization, diagnostics and monitoring are made possible by the IO-Link interface remotely and the integrated display on site. Compact design and high efficiency reduce space requirements and operating costs.

The SITOP PSU8400 3-phase power supply can also be operated on 2 phases without reducing power.

Enhance reliability

With its robust design, SITOP PSU8400 enables stable operation in unstable supply networks, even on only 2 phases in the event of a phase failure. Use the power reserves for a high overload capacity.

SITOP PSU8400

Reduce downtime

Achieve time-saving commissioning thanks to fast IO-Link parameterization, especially for series machines or when replacement. Minimize downtime with comprehensive diagnostics for early detection of critical conditions.
