Hi all,
I am working on a remote monitoring project, gathering voltage and current measurements from an off grid Photovoltaic system.
In order to measure current flow, I have selected an LEM HAIS 50s current transducer which needs a +-15V and ground supply to operate. However, the only power available to us is a 12V battery. I'm hoping someone will be able to point me in the direction of a suitable converter.
The only thing I can think of is to have two switch mode converters side by side, one converting +12V to +15V and one converting +12V down to -15V. I would prefer not to go down the road of building these from scratch! I have had a look at TIs range of converters as I thought there was bound to be an off-the-shelf solution but I've come up empty so far.
Likewise, if anyone could recommend an alternative Hall Effect sensor to the one mentioned that may be another option.
