This miniature and yet powerful LED illuminator is intended for the powerful applications using optic fibre systems. Its high intensity of light output makes it ideal for use with sideglow applications and long distance endglow fibre system. Its active cooling system using the state-of-art ventilation system makes a minimum noise (16dB), which is great especially for low level applications such as private places. Device is regulated by a microcontroller that continuously detects its maximum allowance temperature (48°C). When reaching this borderline the device is automatically turned off and cooled down and repeatably turned on when safe. Thanks to this feature the overall lifespan reaches much longer operating hours than any other temperature non-controlled units. This does not mean that there is no need to prevent high surrounding temperatures at the installation point! Good ventilation system should be secured at all times and for all electrical devices! Since the light output is so strong, the optical port and hence optic fibres have to be polished to the glass-like finish, otherwise you run a high risk of fibres being melt down and limiting the light emittance to a minimum. Never look into the LED illuminator directly nor point at any life objects whilst the device is in operation! LED illuminator requires a stable 24VDC input for its proper cooling and protective electronics' functioning so always make sure that there is no other voltage input than 24VDC. For the dimming and controlling purposes based on 24V constant voltage power systems and 24VDC PWM systems there is a separate input on the device so you can easily control its individual channel/s dimming.
