Revision as of 13:58, 24 October 2019
The power supply recommended for AC powered installations where the observatory is located close to the AC power supply is the Meanwell GST120A12.
For observatories with heaters and long DC power cable runs the Meanwell HRP-300-12 is recommended as it's remote sense functionality allows it to compensate for any voltage drop in the long cable runs. (If no heaters are present, the Meanwell HRP-150-12 is the preferred option.)
Direct links to order Meanwell HRP-300-12 from USA:
HRP-300-12, Mouser Electronics
Accessories for Meanwell HRP-300-12:
TRC-E-HRP300450600 enclosure for HRP-300-12
US/Canada power cord for HRP-300-12
Outdoor Cable
The recommended off the shelf for use on roofs or outdoor structures is the sunlight and abrasion resistant AlphaWire EcoFlex PUR 80045 SL005 (unshielded) or 80145 SL005 (braid shield). Digi-Key usually has one or the other in stock: 80045 SL005, 80145 SL005.
That cabling doesn't have a twisted pair, so we recommend wiring up the conductors to the green numbering in the two images below.
Recommended wiring on the power supply side for a 6 or 7 conductor cable (twisted pair will most likely not be present in off-the-shelf cables) You should use Blue 3mm Fork Crimps to terminate the conductors for L,N,E,-V and +V. This power supply should be installed in a metal enclosure which should be connected via grounding studs to the Earth terminal. The enclosure's door or access panel also needs to be connected. See the Meanwell HRP datasheet for sense connector details.
Recommended wiring on the observatory power plug side for a 6 or 7 conductor cable (twisted pair will most likely not be present in off-the-shelf cables) Conductors 1 and 6 will need to be soldered to the side of C and B if thick conductors are used. The transition from insulated wire to contact needs to be covered by heat shrink to prevent short circuits if the cable subject to twisting torques.
