Direct Current String Monitor
DC Monitoring for Combiner Boxes
DESCRIPTION
The EA10 DC monitoring system provides the perfect solution for string monitoring
in combiner and sub-combiner boxes or other DC loads. The modular construction
allows easy installation for monitoring 8 to 32 strings in a single system. Pulse Reset
technology means no output drift and immunity to power spikes and surges up to
20kA.
This system includes a communications unit that supplies power and provides
Modbus communication. Up to four current sensing modules can connect serially
to one communications unit, each with eight DC current sensors, for a total of 32
monitoring nodes. Connect up to 63 communications units in a daisy chain for
full system monitoring. All boards can be mounted on standard DIN rail for easy
installation.
APPLICATIONS
