  • Overview
  • Series Specifications
The H8238 Multi-Circuit Monitor power monitoring system provides a convenient solution for monitoring multiple electrical services which 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. The H8238 is a UL508 open type device without enclosure.
APPLICATIONS
  • Tenant submetering
  • Real-time power monitoring
  • Activity-based costing
  • Managing loads
Monitor power parameters from up to 8 services with one device
  • 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 connection to up to 24 industry standard five-amp CTs
Modbus communications 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
  • Voltage Tolerance 90 - 132VAC line-to-neutral
  • Electrical Services 120/240 VAC with neutral, 208Y/120 VAC line to neutral
  • Power Consumption 50VA
  • Insulation Class 600VAC†
  • Internal Isolation 2500VAC
  • LCD Display 1.2" (31mm) x 3.8" (97mm) viewing area, 160 segments, back-lit with green LEDs
  • Sample Rate 1280Hz
  • Operating Temp. Range 0° to 50°C (32° to 122°F) (<95%RH, non-condensing)
  • Storage Temp. Range -40° to 70°C (-40° to 158°F)
  • Systems Accuracy ±1% of reading from 2% to 100% of the rated current of the CTs, accomplished by matching the CTs with a meter and calibrating them as a system
  • Frequency 50/60Hz
  • Protection Class NEMA 1

*not supported at >1600A**not supported at >2400A†Do not apply 600V Class current transformers to circuits having a phase-to-phase voltage greater than 600V, unless adequate additional insulation is applied between the primary conductor and the current transformers.
