125 Volt Transportation Module
ASK Technologies’ 125V Heavy Transportation series of ultracapacitor modules is a high-performance energy storage product line for hybrid buses, trucks, trolleys, light rail, mining, construction and seaport cranes. Each model incorporates balancing, monitoring and thermal management capabilities to ensure industry-leading charge/discharge performance, high reliability and long operational life.
The HTM125 meets or exceeds transportation industry requirements for environmental susceptibility. The low equivalent series resistance provides the highest power capability required for heavy machinery. Used as the sole energy storage or in conjunction with batteries, Maxwell ultracapacitor modules provide the high efficiency recharge and high power required for acceleration.
The HTM module now comes with E-mark certification for public transportation according to 72/245/EC and UN10.03 standards.
