I have to purchase DC Power Supply 1. Topward 6303D, 2. Caltron PR 3303SE which one is best

Hi Dear All,
I have to purchase a used power supply. I have two options, 
1. Topward 6303D
2. Caltron PR 3303SE
I have downloaded the operating manual of S. No. 1 but couldn't find that of S. No. 2. I need durable, high quality and easily repairable out of these two options. Price is not an issue.
I will be highly obliged if you guide me to choose the right one.
Thank You.

  • Both are generic OEM designs. I would not expect to find detailed information on either.

    This means one company designed it and sells it under multiple brand names. Sometimes there are minor variations as parts get substituted. I've seen both, but based on the picture, the Caltron design is more common to me.

    They're both linear supplies, so they should be straightforward to troubleshoot and repair even without a schematic.

    As with all supplies, my hard requirement is to have an output on/off control. I hate supplies that only have an AC Mains control.
