Baader OTP II Outdoor Telescope Power 19W
The perfect power supply for smaller telescopes
This power supply for outdoor use has been specially designed to meet the needs of amateur astronomers at northern latitudes. This 12.8 V/1.5 A fixed voltage power supply with reverse polarity protected protective-disconnect elbowed plug fits for example to all smaller Celestron mounts (Advanced GT, NexStar SE, NexStar SLT, LCM, CPC) and offers great advantages at a slightly higher price compared to normal indoor plug-in power supplies. It also fits all other common telescope mounts and devices with this power requirement and plug (tip positive/plus inside, plug diameter 5.5mm)
When used outside in the cold the voltage will reduce with temperature. Already at -10°C the remaining voltage output may have gone down to only 10.5 V. The motors of many telescope mounts will behave erratically at such low voltage. Especially the motor driver electronics then try to replace the missing voltage by draining ever more Amps until both - power supply and mount electronics - will stall or become damaged. Many users then blame the mount and its messy electronics - instead of checking whether an inadequate power supply may be the culprit.
The Outdoor-Telescope-Power II power supply unit, therefore, offers 1.5 A/12V DC voltage all across the AC voltage range from 100 to 240 volt which is common worldwide. Even at extremely cold temperatures, the voltage cannot drop so low that the electronic components or the motors of a telescope mount would suffer damage.
With 1.5 Amp/19 Watt continuous output, there is sufficient power reserve even at full load, even with heavy instrument loads on the mount and large load changes. In addition to the increased outdoor voltage, the working temperature has been designed for -25° to +40° .
The connecting cord between the power supply unit and the elbow plug measures 2.5 m in length so that the power supply unit will not become a trip hazard and can be conveniently placed near the floor. The elbowed plug does protect the power cable from accidental breakage and especially the telescope power input socket from damage when actually someone would trip over the cable. When accidentally the cable gets tightened, the connecting elbow plug will release the cable straight, without ripping or damaging the power socket affixed in the telescope.
The housing is encapsulated against moisture. Ideal for the traveling amateur astronomer!
