The TDK-Lambda JWS600-48 is a single-output AC-DC industrial power supply delivering 624W at 48V DC / 13A in a forced-air cooled enclosed format. Universal input accepts 85–265V AC (47–63Hz) or 120–330V DC, with power factor and harmonic correction to EN61000-3-2. Built-in over-current protection (13.7A limit, auto-recovery) and over-voltage protection (55.2–64.8V shutdown, manual reset) safeguard connected loads. Remote sensing, remote ON/OFF control, and power-fail signal output enable flexible system integration. Typical efficiency reaches 83–85% with 20ms hold-up time at nominal conditions. Operating range spans −10 to +65°C with derating above 50°C; output voltage adjustable ±10% via trimmer.
