The Phihong USA PSA45-150 is an open frame AC/DC power supply designed for various applications. It operates with a universal input voltage range of 90-264VAC and a frequency of 47-63Hz.
This model provides a single output of +15V with a convection-cooled current rating of 3A, increasing to 4A under 20CFM airflow or peak conditions. It delivers 45W of power under convection cooling and up to 60W with forced air. The efficiency is rated at 70% at 45W, 120VAC, 60Hz.
Key electrical characteristics include line regulation of +2%/-4% and load/cross regulation of +2%/-5%. It has a hold-up time of 12ms at a 45W load and 120VAC. Overvoltage protection is provided by a crowbar circuit on V1, and overcurrent protection features auto-restart for short circuits.
Mechanically, the PSA45-150 has dimensions of 127.0mm x 76.2mm x 30.0mm (5.00" x 3.00" x 1.20") and weighs 0.27kg (0.87Ib). It is designed for chassis mounting. The operating temperature range is 0°C to 50°C. Safety approvals include CE, CSA, TUV, and UR.
