Characteristics：(All digital control permanent medium
frequency supply power)
Medium frequency supply power is composed mainly by rectification
circuit, inverter circuit, DC reactor and control circuit, our
supply power is controller with a board of the integrated circuits.
Introduce following a few specifically:
★This power source adopts the inverter of parallel connection.
It’s
Used in various metals melting and holding furnaces and induction
heating installations.
★Main power cable can do not divide phase order (phase order
automatic adjustment)
★It makes operator need not select to start voltage and start
frequency that advanced sweeping frequency starts technology,
with start frequency can be realized that the success of 100%
to start.
★ This power source adopts the advanced control technical
ability,
That has very strong interference rejection.
★ Follow load change voluntarily, have fault when running
it can be
restarted automatically as well as power automatic regulation
function.
★ It has ideal barrier over current , over voltage function
, accurate
barrier broken time or inverter angle control, guarantee that
reliability running.
★ Below have perfect multistage protection system (water
pressure, short phase, short voltage, over current, over voltage,
off time and operating chain etc.) and have the higher efficiency
of frequency conversion and 1000HZ is larger than 95%.
