AS Series

Current Sensors are designed as a low cost method of controlling, monitoring or measuring AC currents. The sensors serve as feedback elements between the output and pulse control circuitry providing accurate regulation of switch mode power supplies.

Features

• Fully encapsulated for optimal PC board mounting
• Frequency range from 2OkHz to 2OOHz
• Primary current rating to 15 Amps
• Primary to secondary isolated to 2500 AC
• Meets VDE noms
• UL 94-V0 recognized materiaals
• Optimum performance over designated current an frequency rage Competitive pricing due to high volume production
  

  Manufactured in ISO-9000 approved facility
  
  Aplications
  Isolated current feed-back signal in Switch Mode Power Supplies - Motor current load/overload - Lighting Switch Controls Ultra-sound current - High resolution sonar current - Isolated bi-directional current sensor with full wave bridge rectifier.

  Notes: 1) Lsec : Secondary inductance tested at l0kHz and l.0mV 2) This nominal termination resistance value will yield approximately 1.0V of output for each amp of current in a single turn sense line. The output Voltage/Ampere of these devices can be increased or decreased linearly over a restricted temperature range by adjusting the terminating resistance. 3) The Isec value corresponds to a maximum primary current of 15 Amp-turns RMS 4) VmS = Rt x ls x (1/2F) Rt (Ohms): Recommended Terminating Resistance Is (A): Secondary Current F (Hz): Frequency 5) Operating Temperature Range: -40°C to +120°C 6) Pin 2 is on Center-Tapped (CT) versions only
