Specifications

The ILD100DC is designed for small vehicles but can be used to drive single turn perimeter loop applications from a 12v power source.

Room aspect ratio 1:1 2:1 3:1
Maximum area coverage m2 120 150 200

 

For any Induction Loop System, area coverage is dependent on several factors. Please check these assumptions and contact Ampetronic for advice if required:

  • The loop is 1-2m above or below the receiver height
  • There are no metal structures in the plane of the loop
  • There is sufficient voltage to drive the cable length – check table below.

Maximum Cable Length

The ILD100 is designed for SINGLE TURN loops for optimum audio quality. When maximum current output is required the ILD100 can drive

  • Loops with DC resistance from 0.2Ω to 0.8Ω
  • Impedance up to a maximum of 0.9Ω

When operating below maximum outpuit, the ILD100DC can drive longer cable lengths – contacts us for more details.

Maximum cable length is dependent on cable type and on the application.

Cable type Maximum Cable Length (m)
Normal Use* Transient Speech*
1.0mm2 copper 34 39
2.5mm2 copper 40 49
4.0mm2 copper 46 59
1.8mm2 flat copper tape 60 70

 

* Short term speech (e.g. service counter, airport PA system) can cope with limited clipping at high frequencies – Ampetronic recommends delivery of full current up to 1.2kHz for these applications.
Longer term usage or signals with music or high quality audio must deliver full current to at least 1.6kHz to prevent fatigue and give acceptable intelligibility. Many commercially available systems do not deliver sufficient voltage to reproduce critical high frequencies – ask us for more details.
