1 Introduction
14 V1.00/EN/00709725 [Thyristor power controller TYA S202]
1.4 Brief description
Device The JUMO TYA S202 is the slim version of the JUMO TYA 202 power control-
ler. It switches resistive inductive loads using a three-phase current economy
circuit in star or delta three-phase operation. The microprocessor-controlled
power controller displays all parameters in an LCD display with background
lighting. It can be operated using the 4 keys at the front.
Application Thyristor power controllers are used where larger resistive and resistive induc-
tive loads have to be switched (e.g. in thermal processing technology). The
thyristor power controller consists of thyristors connected in anti-parallel, the
insulated heat sink, and the control electronics.
Mounting Thyristor 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 power controller works in burst-firing operation. In burst-firing operation,
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, to set
current limiting or resistance limitation for the load.
To avoid high starting currents, a soft start can be set.
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
- Transmission of the setup data is possible even without voltage supply to
the device (power supply via USB port)
- Energy meter
- Same design as the JUMO TYA 202 power control series
