Why is positive polarity important when buying a DC supply?

Positive polarity, negative polarity, reversible polarity; why is this important when I purchase a supply? DC sources are polarity specific. Using earth ground as a reference point, the output of a DC supply can be "X" number of volts above ground (positive polarity) or "X" number of volts below ground (negative polarity).

Do I need a polarity specific DC high voltage source?

Applications that require DC high voltage sources are polarity specific, so the polarity required must be specified at the time of order. Spellman’s High Voltage Power Supply Catalog features a complete listing of all standard Modules, X-Ray Sources, Rack, X-Ray Generator and Application Specific Products.

What is the difference between a positive and a negative supply?

Another way of explaining this, is as a positive supply can source (provide) current, while a negative supply can sink (accept) current. Applications that require DC high voltage sources are polarity specific, so the polarity required must be specified at the time of order.

Why does my outside light stop working if it has power?

This is a common issue that can cause your outside light to stop working even if it has power. To check the circuit breaker, locate the electrical panel in your home and look for the switch that controls the power to the outside light. If the switch is in the ‘off’ position, flip it back to the ‘on’ position and see if that solves the problem.

Why is my outdoor lighting not working?

Sometimes, the wiring may have become loose due to weather conditions or other external factors. In such cases, you can try tightening the connections or replacing the wiring altogether. Another issue that may arise with outdoor lighting is that the wiring may be exposed to water, causing it to corrode and break.
