AS-Interface: Power supply units and data decoupling modules
AS-Interface power supply units generate a controlled direct voltage of 30 V DC with high
stability and low residual ripple in conjunction with data decoupling. They are an integral
component of the AS-Interface network and enable the simultaneous transmission of data
and energy on one cable.
In conjunction with data decoupling modules, AS-Interface can also be operated with
standard power supply units.
IP20, 3 A
IP20, 8 A
AS-Interface power supply units
• With wide performance spectrum from 2.6 to 8 A
• Degree of protection IP20
• Separation of data and energy by means of the integrated data decoupling
• UL/CSA approval means the power supplies can be used worldwide.
2.6 A version with output power restricted to max. 100 W
(for Class 2 circuits acc. to NEC)
• Certified for global use
• Integrated ground-fault and overload detection save the need for additional components
and make applications reliable
• Diagnostics memory, remote signaling and remote RESET allow fast detection of faults in
the system
• Ultra-wide input range enables single- and two-phase applications (8 A version)
Your advantage: Optimum performance for each application.

PSN130S
30 V DC, 8 A
30 V power supply units
Standard 30 V power supply units without data decoupling
• Power spectrum 3 A, 4 A and 8 A
• Overload and short-circuit proof in every performance class
• Diagnostics: If there is an output voltage > 26.5 V DC,
LED and signaling contact for 30V output voltage O.K.
• Primary-side connection to 120/230 V AC (1-phase) with automatic range selection
Your advantage: Economical alternatives in conjunction with data decoupling modules
while making full use of the maximum AS-Interface cable length.
