controller. 

Various diagnostic functions are available, as well as read<strong>ing</strong> 

(via serial line) of current and effective voltage values on 

the load. 

With these functions, various power recipes can be managed 

remotely and transmitted to the s<strong>ing</strong>le units via MODBUS, 

with constant check<strong>ing</strong> of effective power supplied.
