Artesyn's DS1200-3 power supply features a very wide 90 to 264 VAC input voltage range and employ active power-factor correction to minimize input harmonic current distortion. To ensure compliance with the international EN61000-3-2 standard, they have a power factor of 0.99 typical. The power supplies also feature active AC inrush control to automatically limit inrush current at turn-on to 55 A maximum.
The power supply employs a new ultra-high-efficiency conversion topology, together with an innovative power transformer and rectifier construction that further improves power density and reduces interconnect power losses. The power supply’s main +12 VDC payload output is digitally programmable over the range 11.4 to 12.6 VDC, and users have a choice of standard I²C or advanced PMBus™ communications. The control software runs under Windows® on any standard PC, and uses a highly-intuitive graphical user interface to simplify power supply set-up.
The DS1200-3 can deliver up to 98.4 A from its main +12 VDC payload output, and up to 6 A from its +3.3 VDC auxiliary output. The supply has a 1U x 2U form-factor, it measures 10.9 x 3.3 inches, with a height of 1.6 inches, and has a power density of more than 21 Watts per cubic inch. When fed with a 180 to 264 VAC input, the DS1200-3 can achieve a very-high, 91 percent typical, conversion efficiency at 50 percent full load.
