The EPS-65S-3.3 is a single-output open frame AC/DC converter rated for 33 watts of continuous power. It provides a regulated 3.3VDC output capable of supplying up to 10A. The unit operates on a universal input voltage range of 80 to 264VAC with a frequency range of 47 to 63Hz. Typical efficiency reaches up to 91%, while line regulation is maintained at ±0.5% and load regulation at ±2.0%. Output ripple and noise are limited to a maximum of 80mVp-p.
This power supply incorporates robust protection mechanisms including hiccup mode overload protection that automatically recovers after fault removal, and overvoltage protection that shuts down the output until re-powered. It maintains a hold-up time of 30ms at 230VAC and 12ms at 115VAC under full load conditions. The transformer isolation withstands 3KVAC between input and output, with an isolation resistance of 100M Ohms measured at 500VDC.
Housed in an open frame chassis mount enclosure measuring 76.2 x 50.8 x 24.0 mm, the unit supports operation in temperatures ranging from -30°C to +70°C with derating applied above 50°C. It tolerates storage temperatures from -40°C to +85°C and operates in humidity levels between 20% and 90% RH without condensation. The device meets multiple international safety standards including UL62368-1, IEC62368-1, and EN60335-1, and carries CB, CE, cURus, and TUV approvals.
