PSI135

Power supply modules type PSI135 feed the backplane and the internal supply sections of plugged modules. The integrated galvanic isolation decouples disturbances and separates supply groups strictly. Up to 4 PSI135 modules can be operated simultaneously on one backplane, providing supply redundancy in the event of a primary supply or infrastructure failure. The remaining load is distributed evenly on the unaffected modules. The devices measure all relevant quantities of supply and load circuit automatically, aggregate them to meaningful diagnostic information on the application interface as well as visual indication.

• 35 W nominal power delivery at Ta = -30 °C to +70 °C

• Galvanic isolation of 850 V AC, rms for the system 
• Supply redundancy due to multiple power feeds
• Measurement of supply and load circuit 
• Extended diagnostics and load units
• Fail-safe event log
