描述

The 81.000.6110.0 is a primary switching power supply designed for single-phase AC or DC input conversion to regulated 24 V DC output. It delivers a rated output power of 30 W at 1.25 A with an adjustable output voltage range of 24 V to 28 V DC, featuring short-circuit protection with current-limiting fold-forward behavior and overvoltage protection between 125% and 137.5% of rated output. The unit accepts input voltages of 100–240 V AC (85–264 V AC) or 90–375 V DC with a line frequency of 47–63 Hz, achieving typical efficiency of 86% and maintaining full load operation up to 60 °C ambient temperature. It includes a green LED "DC OK" indicator that activates at 19.2 V DC output, an open-collector OK terminal for external signaling, and is UL1310 Class 2 certified with isolation voltage of 3000 V AC / 4242 V DC. The supply is mounted vertically on a 35 mm DIN rail, operates over -40 °C to +71 °C, and is ideal for industrial control systems, automation equipment, and safety-critical applications requiring reliable, regulated low-voltage DC power.
