What devices can I power with this 12V/3A power supply?
Shelyak states it is suitable for most of its instruments: the Lhires III, the LISA calibration module, the Alpy / UVEX calibration module and the SPOX. Contact us before using it with the PF0082 high-voltage power supply and the eShel / Whoppshel calibration unit. Always check your device's manual for its specific power requirements, including the connector size (2.5mm x 5.5mm) and polarity (center-positive).
Can I use this power supply with the PF0082 high-voltage supply or the eShel calibration unit?
Contact us first. Shelyak asks to be contacted before this supply is used with the PF0082 high-voltage power supply and the eShel / Whoppshel calibration unit.
Is this 12V/3A power supply regulated?
Yes, this is a switching power supply, which means it provides a regulated 12V output. This is crucial for sensitive electronics in astronomy gear, as it protects them from voltage fluctuations and ensures stable operation.
How do I check that this supply suits my instrument?
Check that your instrument takes 12V DC at no more than 3A through a 2.5mm x 5.5mm center-positive plug. Shelyak names the Lhires III, the LISA calibration module, the Alpy / UVEX calibration module and the SPOX as suitable.
What is 'center-positive polarity' and why does it matter for this power supply?
Center-positive polarity means the center pin of the 2.5mm connector is the positive (+) terminal, and the outer barrel is the negative (-). Using a power supply with the wrong polarity can permanently damage the electronics in your instrument. Always confirm your device requires a center-positive connection before plugging it in.
The power supply comes with a European cable. How do I get a US version?
The unit includes a European format (220V) mains cable as standard. If you are in a region that uses 110V mains voltage, such as the United States, please contact us to request the appropriate US format cable.
