Description of Connectors PIN

Extremely low standby power.

The JAB series was able to continuously reproduce the playback time up to 24 hours, which was tested with the connected Bluetooth music and the Jazz style songs reproduced continuously. The maximum output voltage on the speaker is 4 V RMS and the load is not less than 5%. Sure Electronics also offers a solution with continuous playback time up to 60 hours, which is more than 2 days with only 2 hours of fast charging. This version can only provide a maximum output of 7.5 Watts at 4 ohm loads, but this is already sufficient for most applications. The standby time is calculated with Bluetooth always enabled, which means that Bluetooth can always be searched. Its 7-day standby time is not reached by stopping the Bluetooth module. So comparing with competitive products, we can achieve a 4 times higher standby time with a high and ffi cient DC / DC converter and a low power consumption microcontroller like PMU (Power Management Unit).

Optional extensions.

Sure Electronics has released an interface extension card to provide a simple panel mounting solution for customer applications. The on-board interfaces include a 3.5mm AUX jack, two USB 2CKT ports for charging, a toggle button with LED power indicators. With headers or a 10-pin cable, the interface extension card will be connected to the amplifier board and quickly integrated into the system. The Sure Electronics cells 3/4/5 in series 18650 Balance for lithium ion batteries and protection board are specially designed for type 18650 batteries of 3/4/5 cells. Customers can use solar panels for their applications. Remember to use only solar batteries with voltage (open) with 16.5-21.5 V and use 20-100 Watt panels for this application. For example, 3 series lithium ion batteries emit more than 12.6 V when fully charged. The customer could also connect 2 pieces of lithium battery and protection extension boards in parallel to obtain a higher voltage. Cells 3/4/5 of the 18650 series with expansion card for balancing and balancing the lithium ion battery are integrated with overvoltage and undervoltage protection circuits. It could balance the voltage between the batteries.

Aluminum bracket type L. (Optional)

It is quite difficult to assemble the audio amplifier board in an enclosed space like most Kiosk and Jukebox applications. To improve the connection and measurement efficiency and save on installation costs, Sure Electronics offers an L-type aluminum bracket for the JAB series. The aluminum bracket supports the vertical and horizontal installation modes to meet different installation needs. With 4 M3 screw spacers and 2 pre-punched M3 mounting holes, the JAB series audio amplifier boards can be easily installed on the bracket.
