APR 400 B420L
VFD and SCR waveform currents measurement
True rms output
Loop powered 4-20 mA current output
DIN rail or Panel mounting
Switch selectable measuring ranges
Insulating plastic case recognized according to UL 94-V0
Large aperature for cable up to 18 mm
High insulation between primary and secondary circuits
Elminates insertion loss
VFD Controlled Loads:
VFD output indicates how the motor and attached load are operating
SCR Controlled Loads:
Accurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives faster response than temperature measurement.
Switching Power Supplies and Electronic Ballasts:
True rms sensing is the most accurate way to measure power supply or ballast input power.
