The 150 watt power supply LPS150 series has the characteristics of automatic selection of input voltage range, remote sensing, remote inhibition, power failure, single wire current sharing, built-in EMI filter, low output ripple, adjustable output, 135kHz switching frequency, overvoltage protection, overload protection, etc.
The ASTEC LPS150 Series is a 150‑W power supply offering a selectable input range of 85‑132 VAC or 170‑264 VAC and a typical efficiency of 75 % at full load. It provides multiple output options, including 5 V, 12‑15 V, and 24‑28 V, with overload, over‑voltage, and power‑fail protection.
The unit operates from 0 °C to 50 °C ambient temperature (derating 2.5 % per °C above 50 °C) and meets IEC and FCC EMI standards. Mechanical specifications include a 20 ms hold‑up time at 110 W load and an MTBF of over 550,000 hours.
