JUMO TYA 202
SCR Power Controller in a three-phase
economy circuit
For the continous control of ohmic-inductive loads
The JUMO TYA 202 represents a consistent further development of the JUMO power controller
technology and switches ohmic-inductive loads in a rotary current economic circuit. The microprocessor controlled power controller displays all parameters in a back-lighted LCD display and
is operated using the 4 keys on the front.
SCR power controllers are employed where larger resistive and ohmic-inductive loads have to
be switched, e.g. in industrial kiln construction and in plastics processing.
The SCR power controller comprises two SCRs connected in anti-parallel, the insulated cooling
body and the control electronics.
SCR power controllers up to a load current of 32 A can either be clipped onto a 35 mm mounting
rail or fitted to the wall with a mounting plate.
Units with a load current greater than 32A have to be fitted to the wall.
The TYA 202 works in burst-firing mode.
In burst-firing mode, the phase angle can be cut back for the first half-cycle, for driving transformer loads.
Available subordinate controls are U, U
Use of a subordinate control ensures that fluctuations in the supply voltage do not affect the
control loop during the control process.
It is possible to preset a base load.
To avoid high starting or inrush currents, a soft start function is available.
The SCR power controllers comply with the operating conditions according to DIN EN 50178.
Grounding is required in conformity with the regulations of the responsible electrical utility
company.

The power controller acts like a switch and provides the power
by either switching ON or OFF. The switching level is always in
the middle of the selected input range.
At 4 to 20mA it is 12mA, at 0 to 10V it is 5V.

Note:
In the case of air cooling, it must be noted that the
effectiveness of the cooling is reduced the higher up the
device is installed. As a result, the current carrying capacity
of the SCR power controller decreases with such a cooler
as the installation height increases as shown in the image.
All specifications refer to the controller nominal data.
