State of the Art Digital Controller

The N2 Power XL270 is the first power supply in this class to use two digital signal processors to control the unit’s operation. The DSPs monitor the following values:

• Output voltage
•  Output current
• Auxiliary 12V output voltage
• Self-diagnostic feature
• Transformer temperature
• Auto-optimize feature
• The microcontroller enables the main output whenever all the required startup conditions are met, and shuts it down upon command, loss of input power or whenever excessive temperatures or loads are sensed. It always provides advanced warning of an impending shutdown before output power is lost.

Current share option

By using the active current-sharing feature from XL270 CS (Current Share) models, the outputs of up to four power supplies can be connected in parallel to provide higher output power. Multiple XL270 CSs can also be used in redundant or N+1 configuration to provide greater reliability. These power supplies have built-in output OR-ing MOSFETs.
