1.4 Brief description
Device The JUMO TYA 202 represents the consistent development of the JUMO pow-
er controller technology. It switches ohmic-inductive loads using a three-
phase current economy circuit in star-delta three-phase operation. The micro-
processor-controlled power controller shows all parameters in an LCD display
with background lighting and is operated by 4 keys at the front.
Application SCR power controllers are used where larger resistive and ohmic-inductive
loads have to be switched (e.g. in industrial kiln construction and plastics pro-
cessing). The SCR power controller consists of SCRs connected in anti-paral-
lel, the insulated cooling body, and the control electronics.
Mounting SCR power controllers up to a load current of 32 A can either be clipped to a
35 mm mounting rail or fitted to the wall on a mounting plate. Devices with a
load current greater than 32 A can only be mounted on the wall.
Operating
modes The TYA 202 works in burst firing mode.
In burst firing mode, the first half-wave can be optimally cut with an adjustable
phase angle so that transformer loads can also be operated.
It is possible to specify a base load or, depending on the device type, set cur-
rent limiting or resistance limitation for the load.
To avoid high starting currents, a softstart can be set.
Load types All resistive loads and transformer loads are permitted.
Subordinate
control loop Depending on the device type, U, U
2
, I, I
2
, or P controls are available as subor-
dinate control loops. Fluctuations in the mains voltage therefore have no effect
on the control-loop regulation during operation.
Standards The SCR power controllers are in accordance with VDE 0160 5.5.1.3 (5/88)
and VDE 0106 Part 100 (3/83). The system must be grounded as specified by
the competent energy supplier.
Advantages - 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)
