Triggered Spark Gaps EVERYTHING IN A NEW LIGHT. P erkinElmer’s Triggered Ceramic-Metal Spark Gaps are a family of versatile high voltage switches. They consist of three electrodes in a hermetically sealed, pressurized ceramic envelope. Triggered Spark Gaps are generally characterized by a peak current capability of thousands to tens of thousands of amperes, delay times of tens of nanoseconds, arc resistance of tens of milliohms and inductance of 5 to 30 nanohenries.

Triggered Spark Gaps EVERYTHING IN A NEW LIGHT. P erkinElmer’s Triggered Ceramic-Metal Spark Gaps are a family of versatile high voltage switches. They consist of three electrodes in a hermetically sealed, pressurized ceramic envelope. Triggered Spark Gaps are generally characterized by a peak current capability of thousands to tens of thousands of amperes, delay times of tens of nanoseconds, arc resistance of tens of milliohms and inductance of 5 to 30 nanohenries. They are suitable for capacitor switching applications such as flashlamps, electrically pumped gas lasers, medical lithotripters, and as crowbar protection devices. Features • Fast switching operation • High voltage holdoff • Ceramic-metal construction • No warm up period • High current capability • Long life Triggered Spark Gap Ratings O -A PerkinElmer Range, kV Model Min/Max No. (1,10) (2) GP-89 GP-90 GP-91 GP-93 GP-82B GP-31B GP-20B GP-46B GP-85 GP-86 GP-87 GP-70 GP-30B GP-22B GP-12B GP-14B GP-41B GP-32B GP-15B GP-74B GP-81B 0.7 1.3 4.4 8 0.4 2 3.5 8 2 6 10 12 2 6 10 12 12 20 25 40 40 (3) VT Min Trig (kV Open Circuit (5) C 10 C A,C A, C A,B 10 TR-148A 30 TR-180B 300 TR-180B Typical Delay Time* Trigger Mode Recommended * when operated in mode A (Nanoseconds) PerkinElmer Transformer At 70% SBV At 40% SBV (6, 7) TR-148A 100 1000 Simultaneous Ratings Simultaneous Ratings Crowbar Service, Repetitive Switching Typical Life: Typical Life: 5000-20,000 Shots 1-5 Million Shots (11) (11) SBV, kV (4) 2.1 3.4 10 20 1.6 6 11 20 6 15 24 36 6 15 24 36 36 48 60 100 100 2.6 4.2 12.5 25 2 7.5 14 25 8 20 30 42(8) 7.5 19 30 42(8) 42 60(8) 86(8) 120(8) 120(9) 20 20 20 20 5 kA peak 0.1 coulomb 3 millicoulombs/shot lb = 35 mAdc lp = 6 Aac 7.5 kA peak 0.2 coulomb 4 millicoulombs/shot lb = 60 mAdc lp = 8 Aac A A,B A TR-1795 TR-180B TR1700 30 300 25 kA peak 0.4 coulomb 4 millicoulombs/shot lb = 100 mAdc lp = 10 Aac A,B TR-1795 A TR-1700 30 300 50 kA peak 0.5 coulomb 10 millicoulombs/shot A,B A TR-1795 TR-1700 TR-1795 30 300 A TR-1700 30 300 Peak currents up to 100 lb = 200 mAdc kA and charge transfer lp = 15 Aac up to 5 coulombs are obtainable at reduced life (100-1000 shots). Notes 1. Optimum operating voltage is typically 60 to 80% of SBV. 2. Operation below minimum value may result in erratic firing over time. 3. Operation at this value may result in self-firing over time. 4. Represents minimum main-gap breakdown voltage with no trigger applied. 5. Value shown contains safety factor for end-of-life requirements. 6. PerkinElmer TM-11A Trigger Module can be used to trigger all gaps. 7. Transformers listed vary mechanically and electrically. See PerkinElmer Transformer Data Sheet. 8. 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. 9. Designed for high altitude, high holdoff conditions. 10. 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. 11. E = Stored energy in joules ( 1/2CV2), lb = average current in amperes, lp = RMS current in amperes, R = total circuit resistance in ohms, P = average power in watts. page 2 PerkinElmer Optoelectronics GP-89, GP-90, GP-91 AND GP-93 0.25 0.590 ± 0.030 0.062 ± 0.020 0.250 0.050 DIA THRU HOLE 0.062 ± 0.020 0.090 O.D.
