Current Transducer HMS 5..20-P

For the electronic measurement of currents: DC, AC, pulsed...,

with galvanic isolation between the primary circuit (high power) and

the secondary circuit (electronic circuit).

I_PN= 5 .. 20 A

All data are given with a R_L= 10 kW

● Industrial

Notes : ¹⁾It is possible to overdrive V_REFwith an external reference voltage

between 1.5V - 2.8V providing its ability to sink or source approximately

5 mA.

²⁾Excluding offset and hysteresis.

³⁾Maximum supply voltage (not operating)

< 6.5 V

⁴⁾Small signal only to avoid excessive heatings of the magnetic core.
