The SITOP PSU8400 3AC, 24 V/40 A three-phase power supply unit has an IO-Link interface and a display on the front of the device. The display enables easy and comfortable setting and diagnostics on site. Through the IO-Link interface the user is offered comprehensive parameterization possibilities as well as diagnostics information for further processing in higher-level automation systems.

The very high efficiency of up to 96% and the associated low thermal loss is one of the reasons for the very compact design. The robust wide-range input enables worldwide connection and the high static and dynamic overload capability ensures the reliable supply of high current loads.

Power supply units can be connected in parallel to increase performance or for the redundancy purposes. A synchronization cable ensures even current distribution between the power supply units to increase the service life.

To increase the 24 V availability, the power supply units can be combined with buffer, DC UPS, redundancy and selectivity modules.
