DV Power POB30D - DV Power POB30D DC Power Box on ElectricityMetering.com

POB30D is a power supply unit employing the latest power electronics technology. POB30D generates ripple free DC-voltage and it is developed for regular maintenance tests of power circuit breakers. Output voltage is selectable from 10 to 300 V DC.
The POB30D is powerful and versatile unit with possibility to generate at 230V mains supply initial current up to 35A as well as continues current according to the table under the Specifications tab.

The set is equipped with thermal and overcurrent protection. POB30D is easy to use and has accessory cable-set with touch-proof contacts.
The POB30D has very high ability to cancel electrostatic and electromagnetic interference in high HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing appropriate hardware and software.

Applications

POB30D is developed for use in switchyards, electric power and industrial environment. An important part of commissioning and maintenance testing is a circuit breaker testing. POB30D is possible to use in:

minimal-trip voltage-test of the circuit breaker's coils
supplying spring-charging motors
power supply at test with breaker analysers

POB30D have built-in function intended for automatic test of minimal trip voltage. The
minimum trip voltage test is described in a number of international and national standards such as IEC 62271-100, ANSI C37.09 etc. Many other important parameters are possible to test with a breaker analyser. PB30D is then used as a power supply unit. It is compatible with breaker analysers from different vendors. POB30D can also be used as a general power supply unit or a temporary battery charger.
