Technical Integrations
Designed as a drop‑in companion for Li‑SOCl₂ batteries, the EPC1520 prevents “voltage lag” by smoothing the power delivery. Its hybrid architecture supports long-term background energy via lithium and enables bursts by capacitor—for solar‑powered remote modules or RTUs needing occasional high-current draw.
Recommended Storage & Usage
● Do not exceed 4.1 V charging voltage
● Avoid discharging below ~2.5 V
● Keep below 100 °C; avoid fire, water immersion, and short circuits
● Ideal storage temperature: under 30 °C, humidity <60%
EPC1520 Hybrid Pulse Capacitor redefines what's possible in compact, long-lasting, high-current power solutions. Impressively combining decades of lithium reliability with supercapacitor performance, it delivers an energy solution that endures—and performs—when it matters most.
