6.3.2 Current Outputs
The data designated "guaranteed" apply to a mains power supply of
230 VAC and to ohm resistive load (load flow = 1). The data designated
"typical" apply to inductive load.
Table 6-5:
Current outputs
For possible operational limits refer to sections 6.3.4, "Operational Limits in
Conjunction with Mains Supply" and 6.3.5, "Operational Limits with Current
and Voltage Amplifier in Parallel".

systems are valid for
symmetric conditions
(0 °, 120 °, 240 °) unless
specified otherwise.
2. For wiring of single-
phase modes see
