AC/DC Current transducer DHR-C10
The transducer for the electronic measurement DC & distorted AC
waveforms current, with galvanic isolation between the primary (High
power) and the secondary circuits (Electronic circuit). True RMS 0-10V
voltage output.

Easy to mount
VFD Controlled Loads:

SCR Controlled Loads:
Switching Power Supplies and
Panel mounting
High isolation between primary and
VFD output indicates how the motor
and attached load are operating.
Acurate measurement of phase
angle fired or burst fired (time
proportioned) SCRs. Current
measurement gives faster
response than temperature
measurement.
True RMS sensing is the most
accurate way to measure power
supply or ballast input power.
