Surge Generator

A2LAAll of the components used in the measuring of 8/20 surge current and voltage are calibrated at laboratories using ISO/IEC 17025, A2LA requirements and ANSI/NCLS Z540-1-1-1994 procedures. (November 21, 2011)

Our Surge Generator, located in Sonoma, CA, meets the levels and requirements in accordance with the following national and international standards:

  • IEC 61000 4-5 -- Combination Waveform
  • UL 1449 4th edition
  • IEEE/ANSI 62.41 Categories B and C


  • I(n) sequence up to 40,000 amps 8/20┬Ás at 600VAC and VPR at 6kV/3kA- 600VAC in accordance with UL 1449 3rd edition
  • Applies the surge with respect to the AC sinewave from 0 to 360 degrees.
  • Includes a back filter that protects the input 220VAC from surges going upstream and damaging other equipment
  • Programmable to surge as many times as needed with time duration between surges
  • Test data can be measured, stored and queried at any time. Test reports can also be printed out

World Products Inc. has a complete applications and component testing laboratory in Sonoma, CA for use by our customers. At our facility we can offer you technical assistance with circuit protection, international testing specifications and electromagnetic compatibility. Our expertise and equipment are available for customer projects and to find answers to your critical design considerations. World Products is an active IEEE contributing member, USA Delegate (IEEE Liason) to IEC and UL Standard Technical Panel member.

We are also able to characterize the performance of components under both normal operational and harsh environmental conditions. Surge testing waveforms can be saved with our HP 54825A Digital Storage Oscilliscope and reports can be sent to customers via email.
