1 Introduction
12 V1.00/EN/00709718 [Thyristor power switch TYA S201]
1.4 Brief description
Device The JUMO TYA S201 is the slim version of the JUMO TYA 201 power control-
ler. The microprocessor-controlled power controller shows all parameters on a
display with background lighting and is operated using 4 keys at the front.
Application Thyristor power controllers are used where larger resistive and inductive loads
have to be switched, for example in thermal processing technology. The thy-
ristor power controller consists of two thyristors connected in anti-parallel, the
insulted heat sink, and the control electronics.
Mounting 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.
Operating
modes The power controller works in burst-firing operation. Here, the phase angle of
the first half-wave can be cut so that transformer loads can also be operated.
During a soft start, the phase angle is slowly reduced, starting from 180 de-
grees, in order to avoid high inrush currents.
The option of specifying a base load is available.
Load types All resistive loads through to inductive loads are permitted.
In the case of transformer loads, the nominal induction of 1.2 tesla must not be
exceeded (value is 1.45 T in the case of mains overvoltage).
Standards 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.
Advantages - Teach-In function for the detection of partial load failure
- Network load optimization through dual energy management
- Transfer of the setup data is possible even without voltage supply to the de-
vice (power supply via USB port)
- Identical in design with the JUMO TYA 201 power controller series
