TKC-DHR420 series current sensor is a true RMS device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit, the size of primary doesn’t affect test precision, no matter the location of primary in the hole of current sensor. It uses for precision measurement of DC, AC and pulse current.

Mechanical dimension(for reference only)
1. All dimensions are in mm.
2. General tolerance ±1mm
Directions for use
1.When the current will be measured goes through a transmitter, the voltage will be measured at the output end.
(Note: The false wiring may result in the damage of the transmitter)
2.Customs can adjust output amplitude of the transmitter by needs.
3.Custom design in the different rated input current and the output current are available.
