Models: Q624A Solid State Spark Generator. Q624A1014 with threaded terminal nut high voltage electrode. APPLICATION The Q624A is a solid state spark generator (transformer) for use on commercial or industrial gas burners. Electrical Ratings: Voltage and Frequency: 120 Vac, 50/60 Hz. Output Voltage: 10,000 volts. Primary VA Rating: 66 VA at 120 Vac. Spark Characteristics: Firing Rage: 60 sparks per second. Voltage, peak-to-peak: 22,000 volts nonsinusoidal. Firing cycle peak voltage: 15,000 volts ±500 volts, open circuit. Energy Discharge: 200 millijoules per spark. Discharge Time: 0.3 milliseconds per spark. Power Dissipation: approximately 12 watts per second. Maximum High Voltage Lead Length: 15 ft. (4.6 m) Maximum Spark Gap: 1/4 in. (6 mm). Ambient Temperature Range: -40°F to +125°F (-40°C to +52°C). Maximum Ambient Humidity: 95 percent RH. Type of Service: All types of gas ignition; not recommended for use when igniting oil. FEATURES · Ignites gas pilots with spark gaps up to 1/4 inch (6 millimeters) in length. · 15,000 volts peak voltage for reliable lightoff. · Prevents detection of the ignition spark when properly applied in a flame detection system with the C7027,C7035, or C7044 Minipeeper® or C7061 Dynamic Self-Check Ultraviolet Flame Detector. · Ignition spark and ultraviolet detector are synchronized by the alternating current supply voltage; spark occurs on one half of the ac cycle and detector operates on the opposite half cycle. · Recommended for interrupted ignition applications only. · Mounts in the same space used by conventional ignition transformer. ® U.S. Registered Trademark 2003 Honeywell International Inc. 60-2049-7 Q624A SOLID STATE SPARK GENERATOR Mounting: Surface.
