External Resistance (Rext) Control
To control the output current using Rext, select the CC control source in the
CONFIG settings from the following two modes.
•
External resistance control 10 k
Ω
→
MAX OUT (CF21: 2)
The output current (Io) varies in the range of 0 to the rated output current (Irtg)
by setting the external resistance (Rext) in the range of 0 k
Ω
to 10 k
Ω
.
Io = Irtg
×
Rext /10 [A]
Rext = 10
×
Io /Irtg [A]
•
External resistance control 10 k
Ω
→
0 OUT (FAIL SAFE) (CF21: 3)
The output current (Io) varies in the range of the rated output current (Irtg) to 0
by setting the external resistance (Rext) in the range of 0 k
Ω
to 10 k
Ω
.
Io = Irtg
×
(10-Rext)/10 [A]
Rext = 10
×
(Irtg-Io)/Irtg [A]
•
If Rext comes loose when using the 10 kW
→
MAX OUT CC mode, excessive
current may flow through the load. For your safety, it is recommended that fail-
safe 10 kW
→
0 OUT CC mode be used.
•
If you are using fixed resistors for Rext and controlling the output voltage by
switching through them, use a short-circuit or continuous type switch.
