Power supply and consumption
12-24V DC: Typical local DC supply inside equipment where another supply is already present.
Whilst the HLS-2A draws less than 2.9W @ 12V DC with typical signals, you should still check that any existing supply has enough spare capacity.
Loop Performance
The HLS-2A will allow an Audio Frequency Induction Loop system that meets the requirements of IEC 60118-4 to be created, if the system is specified, installed and commissioned in an appropriate manner, including observing Ampetronic instructions.
Datasheet & Specifications
All information specified on this datasheet has been complied in accordance with the IEC 62489-1: 2010 Standard and reflects actual performance in realistic applications.
Installation Advice:
Group connections to input 1/2 with DC power cabling. Keep the loop feed cable separate from other connections. When mounting, use appropriately sized screws for your installation application; and washers when necessary. The enclosure has two screw holes, these can be easily accessed by removing the front of the enclosure.
