I know very little about electronics. I need an ac-dc regulated 24 vdc 5 amp minimum (preferably, but 4 amp may do). I found a Lambda data sheet at:The model I am looking into is JWS100-24/A. They list a maximum current of 4.5 amps. Does anyone know if this is supposed to be a surge current, or the maximum that can be drawn continuously? One supplier (Allied Electronics) states "24 volts @ 3.6 amps" yet the Lambda data sheet says 4.5 amps max which makes me think the 4.5 amps is a surge current.
I need a regulated power supply, but the data sheet on the Lambda power supply does not indicate if it is regulated by using such terms as "regulated" or "closed loop". Can one tell from the data sheet if it is regulated? When I ask this question to the people (women) at Lambda, all they do is send me the data sheet and say they hope this helps (on two occasions).
One individual on another list recommended a 24 volt 6.5 amp switching power supply at Alllied Electronics:A second individual said from experience to use a better power supply from companies like SOLA, LAMBDA, VOGEN, and TRACO and made reference to derating curves. The Lambda power supply mentioned above is a lot more expensive than the Allied Electronics power supply: over $200 vs about $35. Is the higher price for the Lambda really worth it? It will be used to drive two servo motors on a telescope and I need good and consistent telescope tracking accuracy. It seems like I am having a hard time finding a 24 vdc power supply at the amp rating I need in the better quality brands, but it seems cheaper ones, like the Allied Electronics one, are easier to find. I do not know what to think.
