This document describes the technical specifications and features of the Watts LCT43-E series power supply. The power supply is totally enclosed and has a universal input, quick installation, built-in EMI filter, low output ripple, and overvoltage and overload protection. It operates in a temperature range of 0° to 50°C, with a gradual decrease in output power at higher temperatures. The power supply meets the electromagnetic susceptibility requirements of IEC 1000-4, -2, -3, -4, -5, -6, 8, 11 Level 3. It is certified by UL, CSA, VDE, CB, and CE.
The LCT43‑E Series is a totally enclosed, triple‑output power supply offering 47 W total power with built‑in EMI filtering, over‑voltage and overload protection, and a low output ripple. It operates from a universal input range of 85‑264 VAC or 120‑300 VDC and meets IEC electromagnetic susceptibility Level 3 requirements.
Environmental ratings include an operating temperature range of 0 °C to 50 °C, storage temperature from –40 °C to 85 °C, and vibration resistance up to 0.41 G. The unit is certified for UL, CSA, CE, and other safety standards, and is supported by Emerson technical service contacts worldwide.
