Hello!
I'm currently starting a new project and I wanted to experiment with AC alarm system power supplies. (You know those big fat ugly wall-warts you screw on a outlet that have two screw terminals?) Well I currently have a DSC PTC1640U I want to use for my experiment.
The DSC Power Supply Specs:
Primary Voltage: 120VAC 60Hz 0.48A
Secondary Voltage: 16.5V 40VA
My problem is I run my test schematic through a simulator before I build it to avoid problems or components to catch on fire/smoke. It appears my voltage keeps dropping and it looks the only way to fix this, is too add a ground on where the capacitor connects on the bottom (On the schematic I uploaded).
If I do have to add a ground, where does it come from? If my "power supply" wall wart act as one and it's connected through the diodes, where do I connect the ground to exactly? Or ... am I going about that all wrong and have to change something else?
