AS-Interface Power Supply
The AS-Interface bus uses a dedicated 30V DC power supply (AS-Interface power
supply), which is indicated with the AS-Interface mark. General-purpose power sup-
ply units cannot be used for the AS-Interface bus.
• Use a VLSV (very low safety voltage) to power the AS-Interface bus.
Caution
The normal output voltage of the AS-Interface power supply is 30V DC.
Recommended IDEC AS-Interface Power Supplies
Input Voltage
100 to 240V AC
Cables
The AS-Interface bus uses only one cable to transmit signals and power. Use one of the following cable types (the wire
does not have to be stranded).
• Standard yellow unshielded AS-Interface cable (with polarity)
• Ordinary two-wire flat cable
