STWA1AH, Electronic current transformer, Measuring Transducer AC 0-15 A, DC 0-20 mA

AC Electronic current transducer with analog output, Measuring transducer for AC currents

The STWA1AH is a current-transducer for AC currents 0...15 A. With the STWA1AH the value of a current can be evaluated very economically and space-saving.
The output-signal 0...20 mA can be evaluated or displayed with components with analog inputs, e.g. PLCs or ZIEHL TR 210, STW 1000 V2 or MINIPAN^®.

For output-signal 4...20 mA choose our Electronic Current-Transducer Type STWA2AH

• current-proportional analog output DC 0...20 mA = AC 0...15 A (insulated)
• electrical connection via screw less pluggable terminals
• no supply voltage required
• DIN-rail-mount or with screws
• plug-in current transformer (Ø 11 mm)
• max. overload 100 A continuously, 300 A max. 10 s
