The HDT-AS series of panel mounted, closed loop, Hall Effect current transducers are designed for applications requiring the measurement of DC current and DC current pulses.
Features:

• Primary Conductor opening – 35mm (1.38″).
• Closed loop with 4mA to 20mA secondary output (A1).
Other Secondary Output Options:
• A0 – 0 to 20mA
• V0 – 0 to 5V
• V1 – 1 to 5V
• V2 – 0 to 10V
• V3 – 1 to 10V
• Contact-less, non-intrusive current sensing.
• DC current and DC pulse.
