Features
RCC voltage transducer
Compact panel Mount type
Remarks
When sensing voltages, the range of
the sensed voltage can be adjusted
by adding an external input resistor
on the input side.
Advantages
No external power supply is required
Good overall accuracy
Excellent linearity
Low temperature drift
Fast response time
Applications
DC variable inverter
Railway overhead line voltage
measurement
Uninterruptible Power Supplies
(UPS)
