The JUMO TYA 201 is an enhancement to JUMO power controller technology.
The microprocessor-controlled power controller shows all parameters on a
display with background lighting and is operated using 4 keys at the front.
Thyristor power controllers are used where larger resistive and inductive loads
have to be switched (e.g. in industrial furnace construction and plastics pro-
cessing). The thyristor power controller consists of two anti-parallel switched
thyristors, the insulted heat sink, and the control electronics.
All thyristor power controllers up to a load current of 32 A can be either
clipped to a 35 mm mounting rail or fitted to the wall on a mounting plate. De-
vices with a load current greater than 32 A can only be mounted on the wall.
The keypad or setup program is used to select the phase-angle operation
mode with adjustable current limiting, burst-firing operation, or half-wave op-
eration.
In burst-firing mode, the phase angle of the first half-wave can be cut so that
transformer loads can also be operated. In phase-angle operation mode, the
phase angle specified by the controller is slowly reduced, starting from 180
degrees, in order to avoid high inrush currents (soft start).
Users are able to specify a base load or, depending on the device type, select
current limiting or resistance limitation for the load.
All resistive loads through to inductive loads are permitted.In the case of trans-
former loads, the nominal induction of 1.2 tesla must not be exceeded (value
is 1.45 T in the case of mains overvoltage).
Depending on the device type, U, U
dinate control loops. Variations in the mains voltage therefore have no effect
on the control-loop regulation during operation.
The thyristor power controllers comply with VDE 0160 5.5.1.3 (5/88) and VDE
0106 Part 100 (3/83). The devices must be grounded as specified by the re-
sponsible energy supplier.
- Teach-In function for the detection of partial load failure
- Network load optimization through dual energy management
- Transmission of the setup data is possible even without voltage supply to
the device (power supply via USB port)
- Energy meter
