Achieving Intrinsic Safety Compliance with Customized Low-Power microSD Solutions
Brief
A leading global manufacturer of precision instruments needed an ultra-reliable, low-power storage solution for their explosion-proof scales used in hazardous environments. Apacer provided a customized, industrial-grade microSD card tailored to meet stringent intrinsic safety certifications, ensuring the client's products were both safe and compliant while preventing any delays in their time-to-market.
Apacer resolved the issue with a customized industrial microSD card tailored to the customer's application.
Executive Summary
When developing new explosion-proof weighing systems for hazardous areas like chemical plants and oil refineries, a globally renowned precision instrument manufacturer faced critical power management challenges. Standard storage solutions risked violating strict intrinsic safety standards due to excessive power draw and unstable peak currents.
Partnering with Apacer, the client integrated a specifically optimized 4GB industrial-grade microSD card. Through close, real-time technical collaboration, Apacer fine-tuned the storage firmware to minimize peak current draw. This joint effort resulted in full regulatory compliance, enhanced system stability, and a faster time-to-market for the client's mission-critical weighing solutions.
