SPS10A-001 Wallmount Power Supply - How to modify ???
Anyone know how to modify this power supply for different voltages?
There's no potentiometer on the board. AC ADAPTER MODEL : SPS10A-001 (TSA-0285) INPUT : 100-120VAC 50/60Hz 1.0A MAX OUTPUT : 3.0 - 36VDC 3.0-0.41A 15W MAX PRESET : 5.0VDC 2.0A I.T.E POWER SUPPLY MADE IN THAILAND |

Assuming it is a switchmode device, there should be a PWM regulator/controller IC. This IC will incorporate an error amp. Usually, one pin will be connected to an internal reference voltage, while another will connect to the output via a resistive potential divider. Tell us the part number of this IC and we can then advise you how to proceed. - Franc Zabkar -- Please remove one 's' from my address when replying by email. |
