Selectable surges for:

• Short branch circuits
  - 1.2 x 50µs impulse, to 6kV OCV*, 8 x 20µs impulse to > 3kA SCI* (stored energy, 216 joules)
  - .5µs/100 kHz ring wave (damped cosine): to 6kV OCV*, 500A SCI* (stored energy, 7.2 joules)
• Long branch circuits
  - .5µs/100kHz ring wave: to 6kV OCV*, 200A SCI* (stored energy, 7.2 joules)
• Switch-selectable polarity
• Meter to set peak output surge
• Floating synch output just prior to surge
• Full interlock system prevents surging unless all interlocks (including external) are closed.
