Compact 1U DC Power System with Embedded Distribution and 94% Efficiency
The CAPTIN 300FA is a highly modular power shelf designed to power small loads at an operating efficiency of 94% — a world-class performance for 300W rectifiers. As a compact, rack-mounted DC power system, it's designed to support uninterrupted 24/7 operations, and that efficiency brings significant savings in thermal management and operating expenses while reducing carbon footprint.
Just 1RU high and 250mm deep, this PSU shelf can accommodate up to three ECOR0348TN-1A300W rectifiers, embedded output distribution (standard or custom configured), a managed battery connection, an energy controller such as the MCU0x48M4 with OLED screen, and a site and access management module. All elements are modular, so the solution can be sized to fit both the application's needs and budget.
Like all CAPTIN series solutions from Alpha Innovations, the CAPTIN 300FA offers the ability to monitor and control an almost unlimited number of operating parameters over TCP/IP. The solution is based on COMPAS, a fully open platform compliant with ETSI standards, supporting XML, SNMP and web-based services. It integrates easily into network applications and enables large savings in maintenance and intervention costs. For those looking for the lowest initial investment, basic monitoring reports all major alarms on configurable standard dry loops.
This fully hot-pluggable modular solution is configured and fully tested to specification, and remains easily scalable at any time. Standard systems are delivered with one input connection; an A+B feed configuration is available as an option. The system offers full front access for module, battery, and DC load connection or servicing, and can be quickly installed and connected. It can also be configured to support NiMH batteries from ARTS Energy.

FAQ
The CAPTIN 300FA is a compact 1U DC power system for powering small telecom, industrial, or access-network loads, with embedded distribution, battery management, and remote monitoring in a single rack-mounted shelf.
The CAPTIN 300FA delivers up to 900W, using up to three 300W rectifiers with LVD and embedded distribution.
It reaches 94% efficiency, a world-class performance for 300W rectifiers, reducing both thermal management needs and operating costs.
Yes. It includes a managed battery connection with up to 20A of battery current (with LVD), and can be configured to support NiMH batteries from ARTS Energy.
Yes. Rectifiers, distribution, battery connection, controller, and access management module are all modular, so the system can be sized to the application and budget, and expanded later — it's fully hot-pluggable.
