4-20 Ma SCADA Interrupter
BTR-20 Automatic Cathodic Protection Rectifier
BTR-20 is a DSP controlled, fully programmable, high efficiency cathodic protection rectifier designed to keep up with the severe conditions faced in harsh working environment, equipped with all the nesceesary protective components and functions to protect itself under extreme conditions such as overcurrent and overheat or surges coming from any cable connection.
BTR-20 has a high efficiency insulating step down transformer with an efficiency of greater than %90 and is designed to witstand an overload condition of %125 contiuously.
BTR-20 Power Module consists of a Low output ripple High efficiency step down DC to DC converter operating at 50 KHz. High switching frequency allows fast output control and line voltage compensation. Utilisation of a DC to DC converter provides an overal efficiency of greater than %85.
The System is able to diagnose and report critical conditions such as Anode, Cathode or Referance electrode cable brakes and also logs the error codes with time stamp for future analyses (-420 model).
It’s unique feature of being able to synchronize multiple rectifiers through GPS satellites (optional) makes it possible to conduct pipeline diagnostic works without using expensive external interrupters.
