Emerson LPT25 Series 25W Datasheet
The LPT25 Series is a compact (<1U) power module offering 25‑40 W total output with a universal input range of 85‑264 VAC and 120‑300 VDC. It provides three independent outputs, remote sense, adjustable main output, over‑voltage and overload protection, and a built‑in EMI filter. Key features include a 110 kHz switching frequency, low output ripple, and a 2‑year warranty.
Designed for industrial use, the unit operates from 0 °C to 50 °C (derating 2.5 % per °C above 50 °C) and can be stored from –40 °C to 85 °C. It meets multiple safety and EMC standards (UL, CSA, CE, VDE, EN60950, CISPR 22) and offers a MTBF of over 550 000 hours at full load. The device is supplied with optional terminal‑block connectors and an enclosure kit.
