(α)
+24 VDC (±10%) @ 0.5 V pk-
pk max.
50 W max. (operation of valve with max. load) without PFO
50 W plus 10 W for PFO
(β)
+24 VDC / 1500 mA max.
±15 VDC (±5%) / 1000 mA
max.
(β)
+ 24 VDC resp. ± 15 VDC
same as input but:
2.0 A max. at ± 15 VDC
1.5 A max. at + 24 VDC
Calculation of complete power consumption:
= α + β
