Additional features of the 51V module include:

• Incorporates Maxwell’s proprietary DuraBlue Advanced Shock and Vibration Technology (earlier post) into the design, which provides three times the vibrational resistance and four times the shock immunity of previous ultracapacitor-based competitive offerings.

• Meets and exceeds the industry’s highest vibration (ISO 16750-3, Table 12) standard for ultracapacitor modules and has an IP65 environmental protection rating.

  (The IP Codes (international protection or ingress protection) are defined in international Standard IEC 60529 to classify the degrees of protection provided against the intrusion of solid objects including dust, and water in electrical enclosures. The first digit indicates the level of protection against solids from 0 (not protected) to 6 (dust tight). The second digit indicates protection against water, from 0 (not protected) to 8 (immersion beyond 1 meter). IP65 indicates dust tight, and protected against jets of water.)

• Includes an active cooling system, which improves the module’s maximum continuous current rating by nearly 90 percent and ensures optimal performance even in extreme temperatures, down to minus 40 degrees and up to 65 degrees Celsius.

• Has an identical mounting pattern to Maxwell’s current 48V module.

Hybrid bus systems need to perform reliably, even when exposed to harsh conditions such as rugged roads and extreme temperatures. The 51-volt module’s ability to perform during demanding high duty-cycle applications reinforces our ongoing commitment to deliver superior performance and value to our customers.
