UNO Solar Power Supply

Phoenix Contact's UNO Solar is an addition to the UNO family of power supplies and was designed specifically for solar applications. This DC-to-DC power supply can utilize the high-voltage DC string voltage and convert it to 24 V_DC. The advantages of the direct array connection will allow the user to target specific applications.

Advantages

• A direct connection to the array saves trenching installation costs for AC power lines
  • Note that the AC power lines cannot be in the same trench as the signal lines due to possible noise coupling
  • Note that a wireless solution can eliminate the trenching needs for signal lines
• Provides control power with the loss of grid power
• UNO Solar is the first array-powered supply to be approved to UL1741
  • Standard for inverters, converters, controllers, and interconnect system equipment for use with distributed energy resources
• Input range is 300 V_DC to 1000 V_DC
• Output rated at 24 V_DC / 2.5 A
  • Can be wired in parallel to increase current using an UNO diode to decouple
• Powering the SOLARCHECK RSD
• Five-year standard warranty
