Optimum operating voltage is typically 60 to 80% of SBV.
Operation below minimum value may result in erratic firing
over time.
Operation at this value may result in self-firing over time.
Represents minimum main-gap breakdown voltage with no
trigger applied.
Value shown contains safety factor for end-of-life requirements.
PerkinElmer TM-11A Trigger Module can be used to trigger
all gaps.
Transformers listed vary mechanically and electrically. See
PerkinElmer Transformer Data Sheet.

These units must be operated in a liquid or gas dielectric to prevent
external flashover: GP-70 and GP-14B, above 24 kV; GP-32B and
GP-15B, above 35 kV; GP-74B and GP-81B, above 60 kV.
Designed for high altitude, high holdoff conditions.

Other voltage ranges and mechanical configurations are available
on request; for example, the GP-20B can be supplied with a 6 to
16 kV operating range by specifying GP-20B-20. The 20 would be
the SBV and E-E maximum would be 80% of SBV = 16kV.

E = Stored energy in joules (1/2CV

), lb = average current in
amperes, lp = RMS current in amperes, R = total circuit resistance
in ohms, P = average power in watts.
