HLS-2B driver with battery back-up

The HLS-2B hearing loop driver features a DM2 Induction Loop driver in an advanced rugged amplifier enclosure primarily designed for lift/elevator applications or other industrial environments.

The HLS series units feature efficient class D current drive technology to reduce power consumption and heat output and are the only small area induction loop solutions capable of reliably driving most practical small area loops in high metal environments to meet the IEC60118-4 Standard.

The amplifier enclosure is constructed of a robust steel housing and the solution features a battery back-up in the the event of a power failure that will provide 12 hours of standby time and 2 hours in full operation. It is further protected by a 5 year warranty from Ampetronic.

The magnetic field strength and distribution in a lift car will be highly dependent on installation method and the construction of the lift car. It is strongly recommended that you contact Ampetronic for free technical support and advice on the best methodology and design for your specific application.
