Powerful AC/DC power supply for testing circuit breakers.
POB30 is a power supply unit employing the latest power electronics technology. POB30 generates ripple free DC-voltage and it is developed for regular maintenance tests of power circuit breakers. It eliminates use of stationary batteries during testing. Output voltage is selectable from 20 to 250 V AC/DC. The test set is a powerful and versatile unit with possibility to generate up to 35A.

• Light weight - 8 kg only

• Powerful – up to 35 A DC

• Voltage 20V AC/DC to 250 V AC/DC

• Ripple free DC-voltage

• Output protection

• Fully automatic operation

Use the full capabillity of your SA10/SA5
In order to perform minimum trip voltage on a circuit breaker mechanism you need an adjustable voltage source. By using the SA10 together with the POB30D you can perform a complete test on your CB coils.

Make your maintenance of high voltage breakers easy. All data is automatically stored into the system and printed in the test report. The minimum trip voltage test is described in a number of international and national standards such as IEC 62271-100, ANSI C37.09 etc.

POB30D can also be used as a general power supply unit or a temporary battery charger.
