Cooling Recommendations
The unit has 12V terminals for driving one or two fans. One is intended for the power supply and one for the lamp. By default, one in connected to the built - in power supply cooling fan. The combined maximum total output current for both outputs is 200 mA. This leaves 135mA for an external fan. Please note that this output voltage is only available when the lamp is in operation. Temperature of the power supply should be exceed 70°C. Temperature overload protected by an internal temperature switch at 90°C.
Environmental Requirements
- Storage Temperature Range -20°C to +50°C
- Humidity Range 20% to 95% non condensing
- Altitude (operating) 0 ft to 10,000 ft
CAUTION:
SAFETY:
The heat sink is connected to line voltage. Do not touch or connect to PE!
