1.6 Brief description
Device The JUMO IPC 300 is a power converter for controlling resistive heating loads.
Due to its way of operating, the device is also referred to as an electronic
transformer with a pulsating direct voltage at the output. The microprocessor
controlled power controller displays all parameters in an LCD display with
background lighting. It can be operated using the 4 keys at the front.
There is no galvanic isolation between the voltage supply of the power section
and the load voltage.
In addition to the IPC 300 itself, a choke and a mains filter are essential for op-
eration. Here, only the chokes or mains filters that are specified by JUMO may
be used.
Amplitude control ensures that current consumption is sinusoidal and reduces
the phase control reactive power. Synchronous clock pulse control and reac-
tive power compensation are not required.
Advantages It combines the advantages of a conventional variable AC transformer (such
as amplitude control and sinusoidal network load) with the advantages of a
thyristor power switch (such as current limiting, load monitoring, subordinate
control loop, etc.).
Application The converter can be used in all application areas where large resistive loads
have to be switched and no galvanic isolation between the voltage supply of
the power section and the load voltage is required.
Due to the amplitude control (mains current consumption is always sinusoidal),
synchronous clock controls (for burst-firing operation), and reactive-current
compensation devices (due to reactive power with phase-angle operation) are
no longer required.
Item Part no.
