Open frame power supply TPS-MPU24S

AC/DCsingle-outputswitching

Product overview
The TPS-MPU24S-12V is a member of the TPS-MPU24S series of single-output open-frame power supplies. It delivers a regulated 12 V output with a rated current of 2 A (operating range 0–2 A) and a rated power of 24 W, placing it in the 17.5 W / 24 W open-frame class. The unit measures 66.2×30.5×21.2 mm and weighs approx. 39 g. It is designed for natural convection cooling (fanless) for installations sensitive to acoustic noise.

Performance & Protection
The supply provides 3000 VAC input-to-output isolation and a regulated low-ripple output (max 40 mVp-p). Protection features include overload protection (115%–180% of rated power) and short-circuit protection implemented in hiccup mode with automatic recovery after fault removal. Typical efficiency is 85%. Input range: 90–264 VAC or 127–370 VDC; frequency 47–63 Hz. Operating conditions: -25 to 60 °C (see derating), 20–90% RH non-condensing. Compliance: GB4943.1-2011 and EN55032 Class B.
