Source Voltage Use in circuit breaker testing Using the ACTAS testing software, EPOS CV can easily be integrated in circuit breaker tests. This makes it simple to automate tests and carry out a comprehensive analysis of the test results. Step value Current Transformer specifications Frequency Rectification Two-pulse bridge circuit 2) Six-pulse bridge circuit 3) Overcurrent, short-circuit, overload, limitation of switch-on current Retrofit for ACTAS C systems Only a few adjustments are required in order to upgrade an existing ACTAS C system by replacing the original sources with EPOS CV.

EPOS  CV 821 / 831 / 753 . Automatically regulated voltage sources are used in Provides high starting currents and rated currents Integrated control panel for stand-alone operation many different test environments to supply power to EPOS CV voltage sources provide both high output voltage and high output current. Especially when operating motors, high starting currents, which can be several times as high as the operating currents, are required when the full operating voltage is applied. The voltage sources are able to deliver these current peaks. EPOS CV sources feature an integrated control...
