PULS has introduced a product that is capable of providing a dc voltage from a 3-phase ac source. The XT40 family deliver up to 960W from a lightweight, compact package and offers a novel method of supplying dc motors and other non-critical loads in industrial systems. The DIN mounting unit is just 96mm wide and weighs 1.4kg. Up to 96% efficient, it has an operating temperature range of –25°C to +60°C without derating and offers a 25% 'PowerBoost' feature to handle motor start-up currents and similar peak loads. All XT40’s meet EN61000-3-2, active input-transient filtering, have a typical power factor of 0.93 and no inrush current surge.
Four models are available offering semi-regulated outputs of 24Vdc at 40A, 36Vdc at 26.6A, 48Vdc at 20A and 72dc at 13.3A. Two input voltages are available at 400V or 480V. Front panel mounted LEDs indicate dc OK, transformer shut-down, low input voltage or missing phase and impending thermal cut-off.
