  • Measures and reports via C-Bus a system's instantaneous electrical power consumption.
  • Current monitoring requires a split core Current Transformer (CT).
  • Provides confirmation that electrical devices are performing as expected.
  • Supply Voltage 15-36 VDC at 18mA, but does not supply the C-Bus Network.

The 5504CMU is a current measurement unit (CMU) from Clipsal C-Bus. This C-Bus CMU gives the ability to attach split core current transformers (CTs) that measure the current in electrical circuits. By specifying the typical voltage of the installation, the CMU can calculate power with a reasonable degree of accuracy and broadcast this information on the C-Bus network. These broadcasts can then be used by devices such as touch screens or Wiser home control to present the information in a way the user can easily understand. The 5504CMU current measurement unit is DIN rail mounting and connects to the network through RJ45 connectors. C-Bus's 5504CMU is a four channel unit, measuring up to four electrical circuits per unit, and raises C-Bus alerts and warnings messages based on predefined thresholds. The maximum number of current transformers per unit is four -current transformer 5100CT80 is the only type of CT that may be connected for safety reasons. C-Bus system units provide system wide facilities to a C-Bus Network and are an essential part of the C-Bus architecture; vital for its commissioning, programming and integration with other protocols. The Clipsal C-Bus home automation system is a microprocessor based wiring system used to control lighting and other electrical devices. Electramania are an authorised Schneider Electric and Clipsal C-Bus distributor.
