Typical Applications
Smart Metering & Infrastructure: Provides long-term maintenance-free backup power for smart gas, water, and electricity meters requiring prolonged standby life.
IoT & Wireless Communication: Ideal for powering RF, cellular (LTE-M/NB-IoT), and GPS tracking modules that need strong pulse power support during intermittent data transmission bursts.
Industrial Automation: Serves as a reliable energy buffer and peak power supply for industrial sensors, actuators, and remote controllers operating in harsh environments.
Memory Retention & RTC Backup: Acts as a dependable hold-up power source for real-time clocks (RTC), volatile memory cache, and critical system controllers during unexpected main power failure.
Testing conditions
