PSU8400 - Power supply with IO-Link
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 power supply with IO-Link that puts its value on display.
With SITOP PSU8400, you benefit from a highly reliable power supply with IO-Link puts it values on display – right at the device on a display and remotely via IO-Link. SITOP PSU8400 has more to offer than conventional power supply units, including more convenience when parameterizing, monitoring, and diagnosing, high power reserves, a small footprint, and an efficiency level of up to 96%.
The SITOP PSU8400 communication-capable power supply can be conveniently parameterized and monitored remotely via the integrated IO-Link interface. However, parameterization and diagnostics can also be performed on-site right at the device on the display.
SITOP PSU8400 can also be easily expanded using the SITOP buffer, redundancy, and selectivity modules – for maximum reliability and availability.

 - Activate/deactivate power boost (300%/25 ms)
 - Set the startup delay
 - Switch output on/off
 - Lock/unlock
 - Signal critical messages via 3-color LED
 
Parallel connection with absolutely even load distribution
Requirements:
- Identical cable lengths/cross-sections up to the common linking point
 - Shared switch in line feeder cable
 - Matching output voltages
 - “Synchronization connection” between the two devices
 
Benefits:
- Extended device service life thanks to even current distribution (50:50)
 - Constant output voltage in all load cases
 - No uneven load distribution caused by temperature drift
 
Combining SITOP PSU8400 and SITOP add-on modules
- Customised design right up to comprehensive all-round protection with SITOP DC UPS and SITOP buffer, redundancy, and selectivity modules
 - For example, distribution to multiple 24-V feeds and selective monitoring by the SITOP SEL1200 and SEL1400 selectivity modules
 - Small footprint in the control cabinet, thanks to side-by-side mounting with no lateral clearances
