Current Transducer HASS 50..600-S
For the electronic measurement of currents: DC, AC, pulsed, mixed,
with galvanic isolation between the primary circuit (high power)
and the secondary circuit (electronic circuit).

Notes:
1)It is possible to overdrive VREF with an external reference voltage
ꢀ
ꢀꢀbetween 1.5V - 2.8V providing its ability to sink or source approximately 5 mA.
2)Maximum supply voltage (not operating) < 6.5 V
3)Excluding Offset and Magnetic offset voltage
4)Small signal only to avoid excessive heatings of the magnetic core.
