BDSCALES Technical Update: Successful Hardware Upgrade for High-Load Drive of K2 Weighing Indicator
Recently, the R&D & Technical Service Center of BDSCALES has developed a customized hardware modification solution for the common industrial scenario of connecting high-power warning devices, which has been successfully implemented in an overseas customer project.
In industrial weighing integration systems, the K2 weighing indicator is frequently connected with multi-color stack lights, buzzers and external relays for on-site audible & visual alarming. Some high-power stack lights draw huge inrush current at startup. With the original circuit design, such instantaneous high current will impact the mainboard reference voltage, and may trigger false low-power protection and unexpected shutdown, disrupting production operation.
To meet the customer’s on-site requirements, BDSCALES engineering team delivered customized hardware optimization:
- Voltage Bypass Optimization: Adopt voltage bypass wiring technology. A dedicated power channel for the drive circuit is derived from the stable 7.94V power node on the mainboard, isolating interference from external high current to the main power loop and solving voltage drop caused by inrush current.

- Custom Component Upgrade: For projects requiring higher load capacity, industrial high-current drive components can be optionally customized to boost the indicator’s driving capability for external loads. Circuit layout is optimized to reduce local heat accumulation under heavy load and improve mainboard reliability under harsh working conditions.
【On-site Customer Verification】
The modification solution was installed and tested at the overseas customer’s factory. Test results show that, powered solely by battery, the upgraded K2 weighing indicator can stably drive high-power multi-color warning lights. The weighing display remains accurate, with no voltage drop or unexpected shutdown issues.
The successful delivery of this customized solution demonstrates BDSCALES’ solid expertise in weighing technology and fast response capability centering on customer demands. Faced with complex industrial electrical environments, BDSCALES provides reliable and robust customized weighing & control solutions.
