968-B Telephone Type B:
968-B Telephone Type B 9x720 / 5x320, 1500V peak, 40Ω; 37.5A peak.

  • $7,070.00

Surge Testers built to test to the requirements of TIA-968-A, Sec. 4.2.3, Telephone Line Surge, Type B. The surge has an open circuit voltage waveform with a front time of 9uSec and decay time of 720uSec and a short circuit current waveform with a front time of 5uSec and a decay time of 320uSec. The peak output of 1000V / 1500V is set on the front panel meter. The peak short current peak is 25A/37.5A minimum. The polarity is reversible by a front panel switch. Tests L or M are selected by front panel switch as well (not shown). See Actual waveforms in Manual below.

Note:  Options TMM and/or Options 220, 230 0r 240 require Option RE as well.

  • Generates the waveforms required by TIA/EIA-IS-968 (formerly known as FCC Part 68), Paragraph 68.302, for testing of Unpackaged Registered Terminal Equipment and Registered Protective Circuitry.
  • Designed with operator safety in mind: Set up the EUT to the right and behind the tester, and a right-handed operator will find himself standing to the left of the tester, allowing maximum separation.
  • Theoretical graphs and actual graphs showing the output of your tester are included with each MegaPulse within the 968 Series, allowing checks and proof of test setups. Reverse polarity waveforms or L and M tests are available by pushing a button on the front panel. No need to change the test setup. Positive polarity indication minimizes errors.
  • Front panel voltage meter shows residual voltage in charging circuit for safer operation.
  • 1-year calibration cycle.
  • All test leads included.
  • 1 year warranty.
