The QM series accepts a wide input range and can provide between 700W to 1200W from 90 to 264V_AC and 700W to 1500W when the input voltage is 150 to 264V_AC. Up to 18 outputs can be configured, avoiding the need to use multiple power supplies. A seven year warranty is provided as standard. TDK-Lambda has extensive experience in module power supplies, having shipped over one million units. Low speed fan cooling and conservative electrolytic capacitor temperatures extends the QM series field life.
