For transport, assembly, installation, commissioning, operation and decommissioning, the safety
instructions contained in these operating instructions must be applied in any case and made
available to all persons handling this product.
CAUTION
It is important that preset parameters are not adjusted in any way that may cause the Power Con-
troller to overload. In case of uncertainties or missing information, please contact your supplier.
1.1 GENERAL
Thyro-P is a Thyristor Power Controller able to communicate. Below, it is also referred to simply
as Power Controller. It may be employed in any place where voltage, current or power has to be
controlled or regulated in processing technology. Several modes of operation and control, good
coupling ability to process and automation technology, high control precision by application of a
32 bit RISC processor and simple handling ensure that Thyro-P is suitable for new applications as
well.
Thyro-P is suitable for
• direct supply of ohmic loads
• for loads with large R
hot
/R
cold
ratio
• as primary Power Controller for a transformer with subsequent load
Due to use of state-of-the-art thyristors, the Thyristor Power Controller Thyro-P has a type range
up to 2900A, the nominal design loads reach up to about 2860kW.
1.2 SPECIFIC CHARACTERISTICS
Thyro-P is characterized by a multitude of specifi c characteristics, for instance:
• easy handling
• menu-driven user interface
• type range 230-690 Volts, 37-2900A, single, double, triple phase
• broadband power supply AC 200-500V, 45-65Hz
• ohmic load and transformer load
• as well as load with large R
hot
/R
cold
for 1P and 3P
• soft start function for transformer load
• load circuit monitoring
• automatical rotating fi eld recognition for 2P and 3P
• U, U

, P control as well as without control
• operating modes TAKT, VAR, Soft-Start-Soft-Down, MOSI, ASM
(optional sub-operating mode of TAKT)
• control of analog set points or via interfaces
• fi bre optic and RS 232 interfaces as standard
• electrical separation according to EN 50178 chap. 3
• Measured values are given at analog outputs
• 4 set point channels incl. Motorpoti, which parameters can be set
The specifi c characteristics especially include the following options:
• Bus connection via bus adaptor cards to plug into the Thyro-P Power Controller, coupling to
different bus systems, for instance Profi bus, other bus systems upon enquiry.
• Patented ASM procedure for dynamic mains load optimization. The ASM procedure (automated
synchronization of multiple Power Controller applications) is used for dynamic mains load optimi-
zation. It reacts to changes in load and set point, minimizes mains load peaks and associated mains
feedback. Minimizing of mains load peaks means cost savings in operating and investment cost.
