1U Redundant Power Supply 300W TC-300R2U-H Product Description

The 1U Redundant Power Supply 300W TC-300R2U-H was designed for high capacity server storage applications. The horizontal 1+1 power module configuration includes hot-swap and power sharing features. Integrated with Active PFC, triple circuit protection, and EPS12V features, the 1U redundant power supply series provides performance and reliability at an affordable cost.

AC Input 
▪ Voltage: 90~264VAC Full Range
▪ Frequency: 50/60Hz.
▪ Input Current: 8A for 115V AC, 4A for 230VAC.
