Why do metal halide lamps require a ballast?

Starting the lamp: In MH lamps, ballasts provide the starting voltage and ignition pulses (pulse-start lamps) necessary to ignite the lamp. Probe-start MH ballasts, however, can take as long as 10 to 20 minutes to restrike (re-start) a lamp. Pulse-start MH ballasts can restrike the lamp within 2 to 8 minutes of an interruption in current, because they provide high-voltage pulses to start these ElectroporationDelivers high-voltage pulses with the ability to control resistance to small volume samples with high resistance, therefore reducing the time constant of an exponential-decay pulse.

The Eclipse has a minimum window of 10 ns, and about a 90% throughput between 750 nm and 850 nm. KMLabs' compact design allows the driver to be packaged in with the optical unit, thus minimizing the high voltage cable length, and thereby maximizing the

High voltage Holiday Detector

Regulated pulse DC voltage output that won't change under load High voltage spark testers, like the PosiTest HHD operate at voltages up to 35,000V and are typically used on coatings more than 500 µm (20 mils) thick. What is meant by the term 'stick type' or 'wand' holiday detector? A 'stick type' holiday detector is a standalone detector with internal battery power and electrodes that Supercapacitor application guidelinesIn high current pulse applications, the resistive component is the most critical. In low current, long dura-tion applications, the capacitive discharge component is the most critical. The formula for the voltage drop, Vdrop, during a dis-charge at I current for t seconds is: Vdrop = I(R + t/C) To minimize voltage drop in a pulse application, use a Automotive Circuit Protection using Littelfuse AutomotivePulse 5 - Load dump – refers to the disconnection of the vehicle battery from the alternator while the battery is being charged.
