The Elinchrom Compact ELC Pro HD 500 is a newly designed monolight with many professional features, like short recycling times and fast flash durations.In fact, up to 20 frames per second is possible at minimum power. An intelligent low noise, temperature activated fan keeps the head cool and lengthens the life of both the flash tube and modeling lamp. A pre-flash detector lets you integrate your on-camera flash into your studio system.Power, variable continuously from 7 to 500W/s, can be mimicked by the 300W proportional modeling lamp to preview your effects. Although Elinchrom provides one, you can swap the sync cord with a separately purchased 8-channel transceiver for wireless triggering from your camera. The head has one built-in to receive the signal. Flash modes allow you to address special situations. The Sequential Mode enables triggering up to 20 ELCs in bursts or in a continuous cycle. Delayed Mode offers a choice of first or second curtain syncing while Strobo Mode allows single frame stroboscopic action sequences. Finally, the auto-sensing multi-voltage power supply means that you can use the ELC Pro HD 500 anywhere in the world.FEATURES:500WsRecycling Full Power: 0.7 sec @ 115 VACSeven Stop Flash Variability90-265 VAC, 50/60HzIntegrated 8-Channel TransceiverSequence, Delay, and Strobo ModesTemperature Controlled Fan Cooling300W Modeling LampUp to 20 fps at Minimum PowerIncludes Reflector
