Sola DIN-Mount 480VAC to 24VDC Power Supplies
Sola's broad range of standard power supplies will cover almost any industrial application. In addition to one of the broadest ranges of DIN Rail and linear-based power supplies in the marketplace, Sola also offers a three phase input option on many of their SDN DIN Rail power supply products. These power supplies convert 380/480 three phase directly to 24 VDC, providing extremely stable, regulated low voltage without the need for a step down transformer, saving space and money.
SDN Series DIN Rail Power Supplies
The SDN series power supplies provide industry leading performance. Sag immunity, transient suppression and noise tolerant, the SDN series ensures compatibility in demanding applications. Wide operation termperature range, high tolerance to shock and vibration and reliable design make the SDN series the definition of DC power quality. The SDN series includes 480VAC 3-phase to 24VDC power supplies in current ratings from 5A to 40A. In addition, Sola has just released the SDN-C, an advanced version of the SDN. These models combine high efficiency and compact size with new visual diagnostic LEDs to offer the most performance available from Sola/Hevi-Duty.
SDP Series Low Power DIN Rail Power Supplies
The compact, lightweight SDP series power supplies come in output voltages from 5 to 48 VDC and power ratings of up to 100 Watts. These extra small, efficient units are designed specifically for the industrial environment. each unit is rated from -10°C to 70°C, with no derating necessary until above 60°C.
Linear vs. Switcher
Sola has provided both linear and switching technology products for many years. As a leading supplier of power products to the industrial market, both technologies are still important. Switching technology (most of Sola's DIN Rail line) is the predominant method of AC-DC conversion for almost any type of electronic system sold today in the world, from PLC's to desktop PC's.
The small size, lightweight and high efficiency of the switching products give them significant advantages over the linear technology products (Sola's SL and 81/83 series). Sola switching products provide well filtered and regulated DC of typically less than 1% deviation from the nominal output voltage.
Linears are about 50% efficient while their switching counterparts are typically over 80% efficient. Switchers are light enough to mount on a DIN Rail, while only the smallest linears are capable of being securely mounted to a DIN Rail. Linears are still popular today because they do provide very tight regulation (<.01% typically), almost perfectly clean DC, fast transient response and their low component count helps provide a lower material cost for its user.
Linears are typically open frame because of the excessive heat dissipation from their low efficiency. Solas industry standard linears, however, are available with optional covers for safety. Most linears, except for Solas SCL series, are recognized to UL 1950 and cannot meet the stricter temperature requirements of the UL 508 Listing, such as with Solas switching DIN Rail power supplies.
