Emerson Network Power DS1200-3 & DS2000-3 Power Supplies
Emerson Network Power has launched two new highefficiency bulk front-end power supplies for systems
that use distributed power architectures. Rated at 1200 watts and 2000 watts respectively, the new
DS1200-3 and DS2000-3 power supplies generate a main payload output of 12 Vdc and an auxiliary output of 3.3 Vdc for powering standby circuitry. An alternative auxiliary output of 5 Vdc is optionally available. Both power supplies are digitally programmable – they are equipped with an I2C interface and use the industry-standard PMBus communications protocol. Forming the latest additions to Emerson Network Power’s popular and expanding DS series product line, the DS1200-3 and DS2000-3 are intended primarily for use in rackmounting server type applications, such as data centres. The power supplies use an advanced power conversion topology to maximize efficiency and have exceptionally compact form factors; both models have a height of just 40 mm (1.6 inches), which makes them ideal for use in 1U high rack-mounting equipment.
