The CUI Inc. SDI18-5.9-U2-P6 is an AC-DC power supply designed for ITE (Commercial) applications. It delivers up to 18W of continuous power with a nominal output voltage of 5.9V and a maximum output current of 3A.
This power supply features universal input voltage range (90-264 Vac) and operates at input frequencies between 47-63 Hz. It boasts DoE Level VI and CoC Tier 2 efficiency compliance, with a low no-load power consumption of less than 0.075W. Protections include over-voltage, over-current, and short-circuit with auto-recovery.
The unit has a compact desktop form factor (Class I) with an IEC 320-C14 input connector and a 1.50m cord. The output is delivered via a standard barrel plug (2.5mm I.D. x 5.5mm O.D. x 9.5mm) with positive center polarization. Safety approvals include UL/cUL, PSE, and UKCA, certified to 62368-1 standards, with EMI/EMC compliance to FCC Part 15B Class B and CE.
Operating temperature ranges from 0°C to 40°C, with storage temperatures from -20°C to 80°C. The power supply offers 3000Vac isolation between input and output and 1500Vac between input and frame ground.
The output voltage is 5.9Vdc nominal and the maximum output current is 3A, providing up to 18W of power.
It accepts a universal input voltage range of 90 to 264Vac at 47 to 63Hz.
It meets Level VI and CoC Tier 2 efficiency standards, with a maximum no-load power consumption of 0.075W at 230Vac.
It is approved to UL/cUL 62368-1, PSE, and UKCA safety standards, and complies with FCC Part 15B Class B and CE for EMI/EMC.
It uses a barrel plug with 2.5mm inner diameter and 5.5mm outer diameter, 9.5mm length, with positive center polarity.
The operating temperature range is 0°C to 40°C.
