Product Description

Northern Designs' Rail 350 kWh Meter is a multi-function meter measuring kWh, kVARh, kW, V, A, PF & Hz and is DIN-rail mounting, fitting in a standard MCB enclosure.

The standard features on the Rail 350 are 2 pulse outputs, which can be configured for kWh and kvarh. The standard communication is RS485 Modbus, however the Rail 350 is available with a range of IP communications options like MODBUS TCP and other TCP/IP protocols such as HTTP, FTP, TFTP, SNMP.

The various TCP/IP protocols make this the ideal meter to interface directly with energy management software and building control solutions, without the need for data loggers or concentrators.

Web pages are available on the IP enabled Rail 350, allowing users to view important instantaneous values and access the setup pages should the need arise to change any of the parameters.

Product Features:
  • DIN-rail mount (6 Modules wide)
  • Individual Harmonics to the 15th, THD to the 30th (Via Modbus)
  • Multiple communications options
  • Isolated dual pulse outputs
