The maximum output current is 15 A and the power input can be rom an AC or DC sourc
Compact design
The UNITROL 1000-15 has all the elements o
excitation control built inside. A powerul signal
processor running extensive control sotware
guarantees excellent perormance under all
conditions. The chopper type power stage, which
can be supplied rom an AC or DC power source,
enables the use in varied applications. The ront
panel serves or easy monitoring and conguring.
The robust mechanical design guarantees a high
reliability. The applications shown here are
typical examples.
