The Mean Well USA ESP-120-27 is an enclosed AC/DC power supply designed for ITE (Commercial) and Laboratory applications. It operates with an input voltage range of 88V to 264V AC and delivers a stable 13.5V DC output at a rated current of 8A, providing a total power of 108W. The unit boasts an efficiency of 83% and features adjustable output capabilities.
Key electrical specifications include line regulation of ±0.5% maximum and load regulation of ±2.0% maximum. Overload protection is set between 105% and 135% of the rated output power, employing a fold-back current limiting type that recovers automatically. Over-voltage protection is also included, with constant voltage limiting that recovers automatically. The power supply is built to withstand 3KVAC between input and output.
Mechanically, the ESP-120-27 measures 150.0mm in length, 140.0mm in width, and 75.0mm in height (5.91" x 5.51" x 2.95"). It is designed for chassis mounting and is non-waterproof. The operating temperature range is -10°C to 60°C, with derating applied. Safety standards include CSA1010.1, UL3101-1, IEC1010-1, and EN61010-1, with cCSAus and CE approvals. The unit comes with a 2-year warranty.
