JPS300V 5V DC power supplies for LED signs
The JPS300V DC power is a robust option for powering LED signs and other products that require relatively high amperage 5V output. 60A at 5V = 300 watts which is pretty hefty for a DC power supply.
Out of approximately 80 PSUs, we have had around 2-3 fail. This is a roughly 3.8% failure rate in some fairly difficult situations (withstanding fairly intense heat, cold and moisture). Overall I would rate them as a good low-cost option especially if you can keep them cool and dry. You can see them in use below:
Switching wiring from old failed JPS300V to brand new JPS300V
JPS300V is user selectable between 110V AC and 220V AC
The PSU is available for sale via suppliers such as:

I opened a bike store and I got with it a electronic sign JPS300V, the problem is I have no way of programming it. Can you help me?
Hey Henry, the JPS300V is just a DC power supply for LED signs, it doesn’t have any programming capability itself. The programming for the LED sign content is handled by software on a PC connected to the sign’s controller (usually via USB or serial), not through the power supply. You’ll need to identify the brand and model of the LED sign itself, then find the corresponding Windows software for it. If you can tell me the sign manufacturer, I may be able to point you in the right direction.
