Tristar offers preventative maintenance plans to identify and correct potential problems before a crisis occurs for all legacy and new rectifiers that supply your critical telecom system.

Rectifiers play an important role in the telecom industry. Periodic monitoring of these rectifiers for capacitor leaks, loose connections, float voltage and load sharing increases the Mean Time Between Failures (MTBF).

During preventive maintenance, our field service engineers perform a complete check on the control boards, SCRs, diodes, cooling fans (if any), circuit breakers and other assemblies, using a fluke oscilloscope, fluke clamp meter, fluke RMS meter, and infrared camera (optional service) or an infrared gun to identify any hot spots or overheating caused by a load imbalance or loose connections.

Tristar field service engineers will also compare readings indicated on the display monitor of the rectifier with their own calibrated meters to ensure proper calibration of the display monitor.

The preventive maintenance results are recorded, reviewed and reported to our customers for further action.
