Programmable 1,200-W supply suits telecom apps

The DS1200DC-3 is a dc-input 1200-W bulk front-end power supply for systems that use distributed power architectures. It suits systems that are co-located with telecom and central office applications operating from 48-V battery plants and has a 40 to 72-Vdc input voltage range. The supply has a main 12-Vdc output that can deliver up to 100 A continuously, and has an auxiliary always-on output for powering standby circuitry. It is digitally programmable via an I2 C interface and is PMBus compliant.

The bulk front-end power supply is housed in a 1U x 2U plug-in rack-mounting module and features 85% efficiency at half load, and a power density of 21.7 W/in.3 . It has an operating temperature range from −10 to 55C and has a built-in cooling fan with automatic speed control. The supply offers 3.3- or 5-Vdc auxiliary outputs that are rated at 6 and 4 A, respectively. (Contact company for price and availability.)
