RECTIFIERS

• High efficiency Switching Current Source providing 96% efficiencies.
• Due to its high efficiency, less heat is generated, and less cooling is required during operation.
• Ideally suited for microgrids where cold winter conditions exist.
• DC output 0 – 50 volts, and current mode up to 6 amps.
• Output controlled (voltage, potential or current modes).
• Cooling and Over Temperature Protection to prevent overheating.
• Under-Voltage Protection to ensure voltage source is protected (batteries).
• Current Limit - the output current is limited to 12A to protect the power switches (over current protection).
• In-house designed and built by Corrosion Service with a history of quality products and services.

The Corrosion Service Portable Transformer Rectifier Unit (TRU) is one of the most essential tools in the cathodic protection technician’s tool box. The TRU allows a variety of surveys to be performed where they would not otherwise be possible by supplementing, mimicking, or replacing permanent cathodic protection installations. Common applications include coating holiday (DC voltage gradient) and current requirement surveys. The TRU provides high output voltage, allowing the generation of significant test currents even under high resistivity soil conditions. The unit is air-cooled with a continuously variable variac control and is conveniently fitted with an interrupter interface. Standard units are supplied with LED displays in a painted carbon steel cabinet, which is rugged enough to withstand demanding field conditions.
