FEATURES
● Revenue Grade measurements
●
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
● Easily connect up to 24 industry standard 5A CTs (solid-core and/or split-core)
● Modbus communication for efficient data collection
●
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
● Use with E8950 gateway for BACnet connectivity...expanded
system compatibility
● Use with U013-0012 serial to ethernet protocol converter...easy
system integration
DESCRIPTION
The H8238 Multi-Circuit Monitor power monitoring system provides a convenient
solution for monitoring multiple electrical services that share a common voltage
source. It 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- and
under-voltage, current, and kVA.
The monitoring capabilities and open systems compatibility of the H8238 make
it the ideal power monitoring solution for OEM, tenant submetering applications,
and load management of power distribution units commonly used in internet data
centers.
APPLICATIONS
● Tenant submetering
● Real-time power monitoring
● Activity-based costing
● Managing loads
