Power Supplies

Watlow Power SuppliesWatlow's series of Class 2, low-profile DIN rail-mount power supplies, only 2.2 inches deep, are ideal for shallow enclosure installations commonly used in building automation and security applications.

The DSP series supplies are available with nominal outputs from 20 to 28 volts and power levels ranging from 31 to 91 watts in three package sizes. Load regulation is less than 1 percent from no load to full load, with ripple and noise below 50 millivolts. To compensate for cable voltage drops, output voltage can be adjusted from the front panel and colored LED indicators immediately confirm the output status.
