Emerson Network Power, a subsidiary of Emerson (News - Alert) as well as the a provider of Business-Critical Continuity, has recently launched the DS1200DC-3, a NEBS certified, high-efficiency dc-input 1200 watt bulk front-end power supply, designed for systems that use distributed power architectures.

The DS1200DC-3 has the capabilities needed in order to be programmed digitally through an I2C interface, and is PMBus compliant. This new system can handle demands for high bulk power, as well as offer a cost-effective solution for current networking equipment.

This power supply boasts a wide input voltage range of -40 to -72 Vdc, and was created to work in conjunction with telecom and central office applications using 48 V battery plants. In addition to its main +12 Vdc output, which can deliver up to 100 amps, the power supply also generates an auxiliary ‘always on’ output that powers a standby circuitry, the press release stated.

Housed in a compact plug-in rack-mounting module, the Emerson Network Power (News - Alert) DS1200DC-3 has a 1U x 2U form factor – it measures just 1.6 inch (4 cm) high by 3.2 inch (8.1 cm) wide. Because this system uses the latest power conversion, this basically means that it has an extremely high level of efficiency. The power supply has an operating temperature range of minus 10 to 55 degrees Celsius, and maintains a built-in cooling fan with an automatic speed control.

The Emerson Network Power DS1200DC-3 power supply is designed for NEBS compliant systems and has already has many different levels of approvals, including UL/cUL 60950, NEMKO+ CB 60950, EN60950, CE Mark and China CCC. The power supply is also fully compliant with the Restriction of Hazardous Substances (RoHS), according to the EU directive 2002/95/EC.
