NWL has been providing specialized power supplies for industrial and research applications for over 40 years.

High Frequency Switchmode Supplies - PowerPlus™ Series -

• Single Unit Power Ratings from 30 to 110kW
• Parallelable to 400kW
• Output Voltages  from  30-150kVDC
• Series resonant operation at 50kHz

These products give the highest performance with the smallest size and weight.   The high frequency DC output minimizes ripple voltage to give a power factor above 0.9; average power is very close to peak power.  PowerPlus was originally designed to provide superior energization for electrostatic precipitators, but we've also developed versions for a variety of industrial applications.

Mid Frequency Switch Mode Supplies – ML™ Series

• Power ratings from 100 to 500kW
• Parallelable to 2000kW
• Switching frequencies of 7kHz
• Input Voltages from 600-5kV Class
• Output voltages AC or DC
  • Oil FiIled from 30 to 150kV
  • Dry Type up to 30kV

This product is perfect for higher power applications requiring small size or tighter voltage control.  Click here for more detailed information on this product.

Linear 50/60 Hz. Supplies – Regulated SCR power supplies and unregulated transformer/rectifier sets.
