Product description

 

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®.

  • 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
