EA10 SERIES
Direct Current String Monitor
DC Monitoring for Combiner Boxes
VERIS INDUSTRIES
EA10
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.
current monitoring
