Commercial Multi-Chargers
for SA1520 and SA1530 Series Receivers

Charger Main | Charger Side | Charger End
The Sound Associates SA1930 and SA1905-10 Smart Chargers take the next step in the evolution of infrared system battery chargers, offering both drop-in charging stations for ease of distribution and charging slots for additional batteries. Each charging position has a multi-color LED indicator that lights when a battery is properly inserted. Red indicates uncharged. As the battery continues its trickle charge the LED will change to green when it is fully charged. This exciting feature virtually eliminates distribution of insufficiently charged or non-functioning batteries.

Each charger includes: one 5 VDC power supply, one coupling cable to charge two units with one power supply, fastening hardware to couple units for additional stability; two battery extractors.


  • Convenient drop-in charging cradles will charge 10 batteries while in the receiver.
  • Multi-charging capabilities to charge to additional 20 batteries in side slots.
  • Recessed LED battery charging indicators at all 30 charging positions.
  • Linking cable to charge two units on one 5 VDC power supply
  • Fastening plates and hardware to connect chargers side-by-side or end-to-end for greater stability.
