Caution
Product Description
[Features]
·Split mounting type with integrated sensor / amplifier structure.
·Available for insulation measurement.
·Supports +/- 15 V power supply, 0 to +/- 4 V output, available for direction discrimination.
·Capable of continuous measurement from DC to high-frequency up to 20 KHz band (when used at high-frequency, it may not be possible to use this up to the rated current).
·High-speed response within 3 μsec.

HCS-20-AP-CL
HCS-36-200-AP-CL, HCS-36-500-AP-CL
HCS-36-800-AP-CL
This product always requires +/- 15 V (+15 V and -15 V direct current dual power supply) as a control power supply.
+/- 15 V is required even for current sensing only on the positive side.
In any case, +15 V alone will not work.

[Note]
(1) Due to the hysteresis of the core, zero-point fluctuation occurs in proportion to the amount of overcurrent that exceeds the rating.
(2) Since the output may fluctuate due to various factors, the range of actual usage should be 5% or more of the rating.
(3) Do not exceed the maximum current for continuous use
(4) There is a possibility of heating due to core loss in high-frequency and large-current applications.
