The Artesyn Embedded Power LPQ353-C is a 350-watt AC/DC converter designed for enclosed applications with chassis mounting. It accepts a wide input voltage range of 85-264 VAC and provides four outputs, including adjustable voltage on the fourth output (3.3-24V).
Key electrical specifications include active power factor correction, an efficiency of 75% typical at full load, and a power factor of 0.99 typical. The converter includes features such as remote sense on the first and fourth outputs, power fail and remote inhibit signals, and single-wire current sharing. It also has built-in EMI filtering and protections for overvoltage, overload, and thermal overload.
With dimensions of 228.6mm x 127.0mm x 63.5mm, the LPQ353-C is suitable for various industrial and commercial applications. The operating temperature range is 0°C to 50°C ambient, with derating up to 70°C. Safety certifications include VDE, UL, CSA, NEMKO, BABT, and CE Mark (LVD).
The input voltage range is 85-264 VAC, and it also accepts 120-300 VDC.
The operating temperature range is 0°C to 50°C ambient, with derating to 70°C at 2.5% per degree above 50°C.
The converter uses chassis mount packaging.
Output 1: 5V, 5A min, 50A max, 60A peak. Output 2: 12V, 0A min, 12A max, 14A peak. Output 3: -12V, 0A min, 6A max, 8A peak. Output 4: 3.3-24V adjustable, 1A min, 6A max, 8A peak.
Overload protection at 110-145% above peak rating, overvoltage protection on the 5V output (5.7-6.7 VDC), and short circuit protection on all outputs.
The MTBF is greater than 550,000 hours at full load and 25°C ambient.
The typical efficiency is 75% at full load.
