Emerson LPT40 Series Power Supply Datasheet
The LPT40 Series provides triple output rails in a compact 3" × 5" footprint that is less than 1U high. It features universal input voltage (85‑264 VAC or 120‑300 VDC), remote sense on the main output, built‑in EMI filtering, overvoltage and overload protection, and a 110 kHz switching frequency.
Designed for business‑critical continuity, the unit meets UL60950, CSA 22.2‑234 Level 3 and CE Mark safety standards, operates from 0 °C to 50 °C ambient (with derating), and has an MTBF of over 550,000 hours. Mechanical drawings, connector pin assignments, and ordering information are included for easy integration.
