Achieving high output and long-duration backup. VPC connects EDLC and battery!
VINATech's VPC (VINA Pulse Capacitor) is an energy storage device that leverages the high output and rapid charge-discharge characteristics of supercapacitors while providing longer power supply durations than EDLCs. While the discharge time of EDLCs is approximately 1 to 30 seconds, the VPC covers a discharge range of about 60 seconds to 1 hour, positioning it as a product that bridges the gap between short-duration high-output applications and long-duration power supply from batteries. The VEL series supports an operating voltage range of 2.5 to 3.8V and offers a lineup from 30F to 250F. It is suitable for applications that require rapid charge and discharge while demanding longer backup times than EDLCs, as well as for energy solutions that assist with battery peak loads.
