Features:
Two working modes: manual and automatic
Can set Test Voltage, frequency range, protective current and
operating time
Dry type epoxy cast, high mechanical strength, good insulation,
nice and reliable.
Adjustable capacity of frequency control source.
Flexible configuration. Different type reactors for option to meet
different test object requirements.
Smaller size, lighter weight compared with same voltage level same
capacity reactor.
Small temperature rise at rated load.
Strong protection, good stability. Multiple functions, cost
effective.
