Controls for Suction Plants Type STW

Stromwandler Typ STWA1

für AC Stromerkennungsrelais

The STWA1 current transformer is made to match the

STWcurrentmonitor.Onecurrenttransformerisrequired

for each line being monitored. The STWA1 consists

of a climate-proven sealed-in coil with toroidal tape

core. The connection cables are permanently ﬁxed to

the transformer and are 1 m in length. The level of the

current to be monitored is limited to 100 A continously,

300 A for max. 10s.

STWA1 for monitoring

current yes/no

In case of current of more than approx. 5 A, an LED

can be triggered directly via the STWA1 current trans-

former. Thus it's easy for users to visually monitor the

current conduction in a line. The LED is protected by

an anti-parallel diode or by its connection in series. A

protective resistor is necessary depending on the LED

used or the level of current being monitored.

A built-in LED lights up at currents > app. 2 A. Even

short current pulses are visible.

ZIEHL current monitor type STW or an external LED

can be conntected to the terminals. The built-in resistor

protects the LED from overload.

The STWA 1 H can also be used to visualize current-

ﬂow in stand-alone mode, without connecting it to a

current monitor.
