2U Redundant 550W Power Supply TC-550RVN2 Product Description

The 2U Redundant 550W Power Supply TC-550RVN2 is equipped with current sharing, universal full range AC input, power fault alarm signals, and alarm resets to facilitate their use and to monitor the power unit. Once any single point fails, the spare module will automatically support your system’s power consumption and keep it working properly. The frontal LEDs indicate whether your unit is in a stand-by, power on, or failed mode. The TC-550RVN2 is a good fit with any of your data center, cloud computing, and enterprise server applications to ensure no power interruptions affect your critical data-processing routines.

AC Input –
Voltage: 90~264VAC Full Range
Frequency: 50/60Hz.
Input Current: 10A for 115V AC, 5A for 230VAC.
Inrush Current: 60A for 115VAC, 80A for 230VAC

Thermal Protection –
The power supply shall go into thermal protection as the case temperature exceeds 86ºC(±5ºC)limit.
The output shall recover only when the temperature becomes normal and AC power is turned on again

Operating Temperature: 0°C to 45 °C
Storage Temperature: -20°C to +70°C
Operating Humidity: 5% to 95%, non-condensing
Storage Humidity: 20% to 90%, non-condensing

Safety & EMI/RFI
Safety Standards: TO MEET CUL UL, TUV
Withstand Voltage: I/P-O/P:1.5KVAC FOR 1 minute. I/P-FG:1.5KVAC For 1 minute
Isolation Resistance: I/P-O/P,I/P-FG,O/P-FG: 500VDC , 50M ohms min.

DC Output
Each of the 1+1 redundant power supply modules shall be capable of supplying the output currents of as below subject to the listed conditions and a total output power of 550watts. Due to active current share, the actual maximum steady state current from each output shall be about half of the maximum current specified.
