EMA212PS24

Designed for communications applications, the EMA212 has been developed to meet the needs of networking equipment, voice over IP systems, wireless LANs, servers, storage area networks and post-production broadcast equipment. Designers of these systems demand higher power from AC/DC units in industry-standard 1U formats as processing power and functionality grows within tight space constraints. The EMA212 delivers over 200W across the full universal AC input range from an industry-standard 3 x 5 inch (76.2 x 127mm) footprint. It is 1.34 inches (34.04mm) high and achieves 10.6 Watts per cubic inch power density without compromising performance or functionality. With efficiency up to 90% at full load, the EMA212 needs only 12 CFM air-flow for full power operation at up to 50°C ambient and will operate at up to 70°C ambient with de-rating. The main output is 12V, 24V or 48 VDC but each power supply also has a 5V, 100mA standby output and a 12V, 1A output for powering a fan. The unit incorporates a fully featured signal set including AC fail/DC OK, remote on/off and active current sharing.

• 90% efficiency
• 5V standby, 12V fan output
• Active current share
• Remote on/off and power good signal
• Only 12CFM airflow needed for full power
• High power density - 10.55 W/In³
