Veris H8238 Multi-Circuit Power Monitor
solution for monitoring multiple electrical services which share a common voltage source. It accepts up to twenty-four industry standard 5A CT inputs and is easily configured for monitoring eight 3Ø, (or six 3Ø plus neutral current) electrical services.
In addition to energy and power, the H8238 also reports diagnostic information
such as power factor, volts, amps, and kVAR, over an RS-485 network using
the industry standard Modbus communication protocol. To protect valuable
equipment, it has built-in alarm registers for over/under voltage, current
and kVA.
The monitoring capabilities and open systems compatibility of the H8238 make it the ideal power monitoring solution for OEM and tenant submtering applications where multiple panelboards are fed from the same power transformer, and for load management of power distribution units commonly used in internet data centers.
The H8238 is a UL508 open type device without enclosure.

The Bad:
The Bottom Line:
Full Review
- Save labor and installation costs by monitoring up to eight 3Ø, (or six 3Ø plus neutral current) loads from a single service with common voltage connections
- Eliminates the need to install multiple transducers- fewer components to install… saves time and space
- Easy connnection to industry standard fi ve amp CTs
- Improve monitoring system efficiencies by accessing 26 data points per circuit, plus alarms, with one RS-485 drop
- Daisy chain up to 30 units on a single drop...easy wiring
- Field-selectable address, baud rate, parity and wiring connections...simple configuration
