DSA Series Power Supplies

XP Power's high-efficiency, slim DIN rail power supplies offer a redundancy module option

Image of XP Power DSA Series Power SuppliesXP Power announces the DSA series of three ultra-slim DIN rail industrial AC-DC power supplies and the complementary DSA-DP20 ORing redundancy module. The highly efficient DSA series comprises the 150 W DSA150, the 240 W DSA240, and the 480 W DSA480. With a single output of either 24 or 48 VDC the range is aimed at industrial type applications, such as process control and building automation, where the space used by the power supply on the DIN rail needs to be minimized. A voltage trim function provides adjustment of the stated nominal output by ¡À5%.

These convection cooled units are narrower than standard DIN rail mount supplies and with the DSA150 measuring 99.8  x  125.2  x  55.5 mm; the DSA240, 117.8 x 125.2 x 65.8 mm; and the DSA480, 123.35 x 124.8 x 86.3 mm, the modules take up minimal space on the DIN rail and provide more power in the available area. The modules' high efficiency rating contribute to using less power resulting in a product that generates less heat, ensuring easier thermal management for the end user. Typical efficiencies are 87% for the DSA150, 92% for the DSA240, and 94% for the DSA480.

The series has an operating temperature range of -25¡ãC to +70¡ãC with the full power output being available without derating from -25¡ãC to +50¡ãC.

Unlike some modules on the market, the DSA series has no line input switches to select and can operate across the full universal input range from 90 to 264 VAC. The series also features multiple options to remotely control the output, giving the user the ability to select how the power supply will respond to over current conditions. The series also features a peak load capability that allows 150% of rated output for up to 3 seconds. This is ideal for high start-up current applications, such as starting a motor, without having to specify a more expensive power supply with a higher power rating just to meet such occasional load conditions.

The DSA-DP20 diode ORing module can be used with the DSA series to provide redundancy for 24 VDC applications up to 20 A. Measuring 99.8 x 125.2 x 55.5 mm in a DIN rail mount package, the module can be connected to two power supplies for 1+1 redundancy or with multiple power supplies and DSA-DP20 modules for N+1 redundancy. The module has volt-free relay contact signals and a visual LED output and failure indicator.

The DSA series meets the international safety standards UL508, EN60950, and IEC60950 in addition to complying with EN55022 Class B specifications for conducted and radiated emissions.
