JUMO TYA 201 - Single-Phase Power Controller (709061)

The JUMO TYA 201 represents the consistent development of the JUMO power controller technology. The microprocessor-controlled power controller shows all parameters in a LCD display with background lighting and is operated by 4 keys at the front.

SCR power controllers are used where larger ohmic and inductive loads have to be switched (e.g. in industrial furnace/kiln construction and plastics processing). The SCR power controller consists of two anti-parallel switched thyristors (SCR), the insulted heat sink, and the control electronics.

The SCR power controller, up to a load current of 100 A, can be either clipped to a 35 mm mounting rail or connected to the wall with a mounting plate. Devices that are larger than 100 A load current can only be connected to the wall.

Depending on the configuration in the setup program, the SCR power controllers − in generalized phase mode − work with adjustable current limiting or in burst-firing mode.

In burst firing mode, the phase angle of the first half-wave can be cut so that transformer loads can also be operated. During the control process, mains voltage fluctuations do not affect the unit to be controlled. Available subordinate control loops are U, U², I, I², or P- control. The option of specifying a base load is available.

In the phase control mode, the phase angle specified by the controller − 180 degrees − is reached slowly to avoid high inrush currents (soft start).

The SCR power controllers meet VDE 0160 5.5.1.3 (5/88) and VDE 0106 part 100 (3/83). The device has to be grounded in accordance with the regulations of the responsible energy supply company.
