| POB30D, POB30AD, POB30DL, POB30ADL, POB40D and POB40AD are power supply units employing the latest power electronics technology. They are developed for use in switchyards, electric power and industrial environment. An important part of commissioning and maintenance testing is a circuit breaker testing. |
Our Coil Testers & Breaker Supply units POB30D, POB30AD, POB30DL and POB30ADL, POB40D and POB40AD have built-in capability to perform
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 analyzer. Coil Tester & Breaker Supply units are in those cases used as a power supply units. They are compatible with breaker analyzers from different
vendors. Coil Tester & Breaker Supply units can also be used as general power supply units or
temporary battery charger. Maximum load time for coil outputs is 1 second.
