LOAD DESCRIPTION ohmic load (minimum 100W)
ohmic load R
hot
/R
cold
ratio up to 20 (MOSI operation)
transformer load
TRANSFORMER The induction of the load side transformer should not exceed
1.45T in case of mains overvoltage when using grain-oriented,
cold-rolled plates. This corresponds to a nominal induction of
approx. 1.3T.
OPERATING MODES TAKT = full oscillation clock principle = default setting for the
models 1P, 2P and 3P
VAR = phase-angle control = only for the models 1P and 3P
SSSD = soft-start-soft-down; a combination of
„VAR“ und „TAKT“, for the models 1P, 2P and 3P,
i.e. reduced mains surge load
SET POINT INPUTS The Power Controller Thyro-P has 4 set point inputs.
The set point inputs are indirectly connected to the mains
(SELV, PELV).
Set points 1, 2: external set point input
signal ranges:
0(4) - 20 mA Ri about 250⍀ max. 24mA*
0 - 5 V Ri about 8,8k⍀ max. 12V
0 - 10 V Ri about 5k⍀ max. 12V
* refer to ”ATTENTION” on page 16
Set point 3: connection for fi bre optic (LL) from the wuper-
ordinate PC or automation system
Set point 4: set point assignment via RS 232 (for instance LBA)
The four set points are added internally and the total of the
set points, for instance for power control, is proportionate to
output power. For set point 2, there are different valuation
options: it may be added to set point 1 or subtracted from set
point 1.
ANALOG OUTPUTS
3 outputs: signal level 0-10 volts, 0-20mA or parameters may be
set differently. The maximum burden voltage is 10V
CONTROL CHARACTERISTIC
The control characteristic is established by the maximum value
of the dimensions to be controlled and the key values of the
set point. Using these key values, the linear control characte-
ristic may be set at will.
Every controller (for instance temperature controller), whose
output signal is in the range of 0-20mA/0-5V/0-10V may be
easily adapted to the Power Controller.
