1.4 Brief description
Device The JUMO TYA 201 represents the consistent development of the JUMO pow-
er 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.
Application SCR power controllers are used where larger resistive and inductive loads
have to be switched (e.g. in industrial kiln construction and plastics process-
ing). The SCR power controller consists of two SCRs connected in anti-paral-
lel, the insulted cooling body, and the control electronics.
Installation All SCR 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. Devices with a
load current greater than 32 A can only be mounted on the wall.
Operating
modes The keypad or setup program is used to select the phase angle control operat-
ing mode with adjustable current limiting, burst-firing mode, or half-wave
mode.
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 control mode, the phase an-
gle specified by the controller is slowly reduced, starting from 180 degrees, in
order to avoid high starting or inrush currents (soft start).
It is possible to specify a base load or, depending on the device type, set cur-
rent limiting or resistance limitation for the load.
Load types All resistive loads through to inductive loads are permitted.
In the case of inductive loads, the nominal inductance may not exceed 1.2
Tesla (at grid overvoltage of 1.45 T).
Subordinate
control loop Depending on the device type, U, U
2
, I, I
2
, or P control are available as subor-
dinate control loops. Variations 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). Grounding is required in conformity with the
regulations of the responsible energy utility company.
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)
