Open-Frame Ac-Dc Supplies Now Up To 250 W

XP Power has added a 50 W range to its GCS series of high efficiency single output ac-to-dc power supplies. Certified to both industrial and medical international safety standards, and comprising 150, 180, and now 250 W models, the GCS series is available in multiple mechanical formats. Ensuring the range is suitable for multiple applications, the GCS series is available in an industry standard 3 x 5 inch (127 x 76.2 mm) open frame package, an enclosed covered version, and top or end-mounted fan cover options.

The open frame format allows the GCS250 to deliver up to 180 Watts by convection cooling, and the full 250 Watts when provided with only a 7 CFM airflow or when using the optional fan mounted configurations. With both Class I and Class II input construction techniques used, designers can opt to use an input earth scheme or not. These highly efficient supplies, typically up to 93% efficiency, are available with outputs covering all the popular nominal voltages from +12 to +48 Vdc. A secondary 12 Vdc / 0.6 A fan supply is also a standard feature, with remote on/off being available as an option.

Suiting a wide range of application environments, the GCS250 can operate over the extended temperature range of - 40 to + 70 °C with no derating until +50 °C. The supplies operate from a wide input range of 85-264 Vac, with full power available from 90 Vac and higher.

No additional EMC filtering components are required since the GCS series meets Class B conducted and Class A radiated criteria as stipulated by the internationally recognized standards of EN55011 and EN55022. Also, the units comply with the 3rd edition medical safety standards EN60601-1, ANSI/AAMI ES60601-1, CSA22.2 No 60601-1, and the IT equipment safety standard UL/EN 60950-1.

Ideal for use in any '1U' equipment, the GCS250 is suitable for a multitude of applications within the industrial and healthcare markets.

The GCS250 series is priced at $81.90 for 500 pcs orders.
