The MERLIN Rectifier Monitor is a small, compact unit housed within the rectifier cabinet. It checks the rectifier performance and communicates (via either an internal or external antenna) using the GSM network. All data is automatically transmitted in a management report to the system HQ where it is accessed online using Abriox’s MERLIN iCPSM software.

MERLIN Rectifier Monitors will carry out the functional checks of rectifier output (voltage and current) required in order to comply with regulatory guidelines. They will quickly repay their capital cost when compared to monthly manual checks.

MERLIN’s will report immediately if an output alarm threshold is exceeded; they will also check that the rectifier remains powered by its external electrical supply. If the power fails, an alarm is transmitted and the MERLIN’s internal batteries take over monitoring for up to 2 years.

A key feature of the Abriox MERLIN system is cellular telephone control. Once installed, monitors are easily and quickly set up using a cellular telephone. Further configuration (e.g. alarm levels) can be programmed and realtime, on-demand readings can be taken of all monitored parameters. In addition, synchronized interruption cycles can be started and stopped directly from a cellular telephone.

iCPSM web software provides access from any internet-enabled PC to a password-protected CP database that is unique to each customer. Users can configure and control MERLIN monitors, view rectifier CP data in graphical and numerical formats or export data for further analysis and archiving.
