peak

, 1 x 1740 VA at 25 A

Both amplifier groups CURRENT OUTPUT A and CURRENT OUTPUT B 
are connected in series. The currents 1 and 2 of a group are phase-
opposite. This results in four times the compliance voltage of a single 
output.

Observe the safety instructions given in Section 7.1 on page 91 when using 
this operating mode.

Refer to the output curves shown in the figures 6-1 through 6-5 in sectio
6.3.2, "Current Outputs" on page 43.
