RADWAG Balances and Scales (Poland) - Press Release: The terminal can operate even though there is no access to a power source in a special design with power supply from an external buffer power supply ZR-03. The special design consists in modifying the standard version of the PUE HX7 terminal to a variant of this terminal adapted for power supply from a buffer power supply ZR-03/2. The ZR-03/2 includes a voltage converter and a powerbank.
In a special design, the PUE HX7 weighing terminal has a 12-24V DC power socket to which the dedicated ZR-03/2 buffer power supply can be connected. The terminal can be powered only from the ZR-03/2 buffer power supply, not from the 110-230V AC mains or the internal battery. The powerbank can be charged using an external charger, after disconnection from the weighing terminal. The powerbank runs on one set of batteries while the other is charging.
The maximum operating time for the HX7 terminal is 20 hours, and the average is 12 hours. The operating time depends on the number of connected peripherals and the power drawn from the terminal.
The ZR-03/2 buffer power supply is dedicated to HX7 scales.
