|
Display of electrical
parameter
|
Line voltage (L-L), three-phase
voltage (L-N),
three-phase current,
frequency, power
|
Protection
|
No fuse switch at input and
output,
the electronic circuit can detect
over-current, over-voltage,
overload,
over temperature, short circuit
quickly, start tripping protection
and alarm automatically
