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.
When using two AS ‐ Interface master modules, two AS ‐ Interface power supplies are
needed. Since the AS ‐ Interface cable transmits both signals and power, each net ‐
work requires a separate power supply.
Recommended IDEC AS ‐ Interface Power Supplies
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
Applicable Cable Specifications
Note: When using single wires, the maximum cable length is 200 mm. See “Maximum Communication Distance” on page 24 ‐ 1.

Use a VLSV (very low safety voltage) to power the AS ‐ Interface bus.
The normal output voltage of the AS ‐ Interface power supply is 30V DC.
