The LPS350 Series is an ASTEC 350W switch power supply with an input voltage range of 85-264 VAC, 120-300 VDC, a frequency of 47-440 Hz, and a maximum input current of 38 A. This product has a typical full load efficiency of 75%, FCC Class B conducted and radiated, CISPR 22 Class B conducted and radiated, EN55022 Class B conducted and radiated, VDE 0878 PT3 Class B conducted and radiated EMI filters, a typical power factor of 0.99, a safety ground leakage current of less than 0.5 mA @ 50/60 Hz, 264 VAC input. This product has a maximum output power of 350 W, an adjustment range of 2:1 wide ratio, 5 V @ 500 mA regulated, and 12 V @ 150 mA x2 monitoring outputs. The hold time is 20 ms @ 350 W load, 115 VAC nominal line at factory voltage setting. This product has short circuit protection, Case overload protected @ 110-145% above peak rating overload protection, 5 V output: 5.7-6.7 VDC overvoltage protection, and 10% to 25% above nominal output logic control.
The LPS350 Series delivers 350 W of regulated power with active power factor correction, remote sense, and built‑in EMI filtering. It supports single‑wire current sharing, supervisory outputs (5 V @ 500 mA and 12 V @ 150 mA), and provides protection features such as overload, over‑voltage, and thermal shutdown.
Designed for industrial environments, the unit operates from 0 °C to 50 °C ambient temperature, meets IEC 801‑3‑2 compliance, and passes electromagnetic susceptibility tests (IEC 801‑2 to ‑6, Level 3). It also complies with FCC Class B, CISPR 22, EN55022, and VDE 0878 standards, and includes certifications such as UL, CSA, and CE.
