Attention:
This sensor module is especially configured to work in very challenging DC-Power Applications where Ripple and Noise is prominent!
It can as well be modified to measure currents in AC mains electricity, but therefore the filter needs to be opened to let low frequency AC pass. Required SMD/size 0805 components to use in AC are: CF1, CF2 : 1uF; RF1, RF2: 1kR
This design is based on the ACS758 Hall current sensor.
ACS758-50B Version:
max. Current +/- 45A at Vcc 5V
ACS758-100B Version:
max. Current +/- 85A at Vcc 5V
ACS758-150B Version:
max. Current +/- 120A at Vcc 5V
Zero Current equals to a sensor output of Vcc/2
Vcc: 3.3V - 5V
Special Features:
active Low-Pass Filter using Op-Amp set at 1,6Hz cut-off Frequency (no AC will pass trough, low Noise)
on-board 1,5V Reference Voltage Source to be used to monitor your Vcc and analog readings
high quality Terminals to connect cables with crimp lugs (rated 120A, M6 screws)
improved isolation between high power side and low voltage side
