The enclosure is a rugged CNC machined aluminum enclosure with an anti-corrosion finish. The 2000mAh battery is user replaceable and provides up to two hours of use for a Valon 5009 Dual Frequency Synthesizer module with both sources enabled. Much longer battery life can be had with using only one source and even longer with one source and a Valon 5008 Dual Frequency Synthesizer module.
The boost converter maintains a 6.0V output from the 3V lithium battery. The boost converter operates at 2.4MHz and provides a well filtered output with minimal switching noise. The boost converter can provide up to 1.25A to the load and is short circuit protected. The load bypass switch is power MOSFET that sends the 6V input current directly to the output when the 6V input is present.
20" pig-tail cable assembly. The optimum input voltage for full performance with a synthesizer or similar Valon load is 6.0 Volts minimum. Make sure the power adapter or power supply can deliver the required current both for the load and the charger. For example, if the load is a 5009 requiring typically 540mA and the battery is being charged, then the power supply or ac adapter must be able to deliver ~1.6Amps.
There is nothing to prevent connecting the power supply or ac adapter/charger into the 6V OUT connector of the UPS6V-2. Doing so will not damage the power supply or the UPS6V-2. Simply disconnect and reconnect the cable to the correct connectors.
2.1mm x 5.5mm barrel power plug adapter is available from Valon for connecting ac adapters to the pig- tail end of the Hirose power cable. Plug this cable into the UPS6V-2 and apply power from the power supply or ac adapter.

Note charging voltage can be lower than the required voltage for the certain 6V products.
