The CAPTIN 300FAR series is a highly modular solution designed to power small loads at operating efficiency of 94%, a world class performance for 300W rectifiers. Designed to support uninterrupted operations 24/7, such efficiency brings significant savings in thermal management and operating expenses and reduces carbon footprint.
1RU high and 250mm deep, the system can accommodate up to three rectifiers, an embedded output distribution (standard or custom configured) including a managed battery connection, an energy controller and a site and access management module.  All elements are modular to optimize your solution and meet your needs and budget.    
Like all CAPTIN series solutions from Alpha Innovations, the CAPTIN 300FAR offers the opportunity to monitor and control an almost infinite number of operating parameters over TCP/IP.  The solution is based on Compas, a fully open platform compliant with the ETSI standards, and supports XML, SNMP and Web based services.  It is very easy to integrate in network applications and facilitates large savings in maintenance and intervention costs. For those looking for the lowest initial investment, the basic monitoring will report all major alarms on configurable standard dry loops.
Enjoy a fully hot pluggable modular solution, configured and fully tested to your needs, that is of course easily scalable at any time. Standard systems are delivered with one input connection; A+B feed configuration is optional.
The system offers full front access for any module, battery and DC loads connection or servicing and can be quickly installed and connected.
This solution can be configured to support NiMh batteries from ARTS Energy.
