MEAN WELL QP Series Quad Output Power Supply
Power Range: 150W to 320W | Quad Output Channels | Built-in Active PFC
General Family Features
The MEAN WELL QP series offers high-performance enclosed quad output power supplies equipped with active Power Factor Correction (PFC).
Power Input & Safety
- All models feature a universal AC input / full range, operating between 90~264VAC or 127~370VDC.
- The built-in active PFC function maintains a power factor greater than 0.95 at full load.
- Standard protections across the family include short circuit, overload, and over voltage safeguards. The QP-320 additionally includes over temperature protection.
Performance & Monitoring
- Cooling is accomplished by forced air through a built-in DC fan.
- The QP-150 series allows for selectable positive or negative polarity on CH4.
- The higher-powered QP-320 series features a built-in PG/PF signal output, remote sense on CH1 and CH2, and a 20A peak load capacity for the 24V channel.
- All models are supported by a 3 years warranty.
