QM

550W - 2000W Modular power supply

The high efficiency modular QM range is available in system fan and low noise fan versions. The 5 models (QM4, QM5, QM5H, QM7 and QM8) within the range cover the range from 550W-1200W low line and 650W-2000W high line. Combining 1 MOPP (1.5kVac) input to ground, 2 MOPP (4kVac) input to output and 1 MOPP (1.5kVac) output to ground isolation, the entire QM range is certified for both medical equipment (making it suitable for BF (body floating) type) and industrial. High efficiency levels of up to 91% are combined with a wide selection of modules to perfectly match your requirement
