PKN 3PHASE SERIES

Networkable Digital Power Amplifiers

Products table:

Model	4 Ohm	8 Ohm	2.66 Ohm
PKN 3PHASE 40K	4 x7500W	4 x 4000W	4 x 10000W
PKN 3PHASE 20K	2 x 7500W	2 x 4000W	2 x 10000W

Features:

- Worldwide highest output power level and greatest extra headroom
- Three or Single* phase very wide range of AC line operation with APFC
- Easy interfacing to the 3X 400V** distribution without Neutral connection
- Reduced current draw and line cabling cost, saves lots of copper
- No more line-to-line balance problems, moreover the amp helps to keep
the best symmetry between phase conductors in 3 Phase operation mode
- Fault-tolerant to power line anomalies, still operational with 2 phases
- Network control over standard ETHERNET, Open Source drivers
- Optional DSP module with 24bit/192KHz HiDefinition sample rate
- Full soft switching implemented with very high power conversion efficiency
- Supercompact size and small weight in rugged 1RU steel case
- Easily readable large format display and accurate output level metering
