Datasheet
- 3.00” x 5.00” x 1.34” - High Power Density 10.6 W/in3 - Up to 90% Efficiency - 5 V Standby & 12 V Fan Outputs - Active Current Share - Remote On/Off - Power Good Signal - -10 ºC to +70 ºC Operation - Universal AC Input 90-264 VAC - Level B Conducted Emissions - 48 VDC Input Versions Available (DMA212) 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 127 mm) footprint. It is 1.34 inches (34.04 mm) 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 12, 24 or 48 VDC but each power supply also has a 5 V, 100 mA standby output and a 12 V, 1 A 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. xppower.com ## Models and Ratings |Max Output Power<br>(12 CFM Air Flow)|Ouput Voltage<br>V1|Ouput Current<br>(12 CFM Airflow)|Fan Output<br>V2|Standby Supply<br>V3|Model<br>Number| |---|---|---|---|---|---| |212 W|12.0 VDC|16.7 A|12.0 V/1.0 A|5.0 V/0.1 A|EMA212PS12| |212 W|24.0 VDC|8.3 A|12.0 V/1.0 A|5.0 V/0.1 A|EMA212PS24| |205 W|48.0 VDC|4.0 A|12.0 V/1.0 A|5.0 V/0.1 A|EMA212PS48| ## Input Characteristics |Characteristic|Minimum|Typical|Maximum|Units|Notes & Conditions| |---|---|---|---|---|---| |Input Voltage - Operating|90||264|VAC|| |Input Frequency|47|50/60|63|Hz|| |Power Factor||>0.9|||230 VAC| |Input Current - No Load||110||mA|| |Input Current - Full Load||2.1/1.1||A|115/230 VAC| |Inrush Current|||60|A|230 VAC cold start| |Earth Leakage Current||0.5|1.1|mA|230/264 VAC 50 Hz| |Input Protection|T5 A/250 V internal fuse in line||||| ## Output Characteristics |Characteristic|Minimum|Typical|Maximum|Units|Notes & Conditions| |---|---|---|---|---|---| |Output Voltage - V1|12||48|VDC|See Models and Ratings table| |Initial Set Accuracy|||±1(V1) , ±5(V2) & ±3(V3)|%|| |Output Voltage Adjustment|||||Not available| |Minimum Load|||||No minimum load required| |Start Up Delay||1.5|3|s|90 VAC full load (see fig. 1 to 3)| |Start Up Rise Time|||20|ms|| |Hold Up Time|16|20||ms|90 VAC full load (see fig. 4 to 6)| |Drift|||±0.2|%|After 20 min warm up| |Line Regulation|||±0.5(V1), ±2(V2) & ±0.5(V3)|%|| |Load Regulation|||±1(V1), ±5(V2) & ±1(V3)|%|0-100% load V1 & V3, 10-100% load V2| |Cross Regulation|||±10(V2)|%|10-100% load change V1| |Transient Response - V1|||4|%|Recovery within 1% in less than 500 μs for a<br>25-75% and 75-25% load step (see fig. 7 & 8)| |Over/Undershoot - V1|||2/5|%|12/48 V (see fig. 9)| |Ripple & Noise|||1(V1 &V3) & 2(V2)|% pk-pk|20 MHz bandwidth (see fig. 11 to 14)| |Overvoltage Protection|115||140|%|Vnom DC.
