Power Supply Units

The first quarter of 2014 will see three different versions of the three-phase ECO power supply units to the EPSITRON family of products. WAGO's power supplies are an alternative when 24 VDC voltage is needed. The existing portfolio of single-phase components will be expanded to include versions for 3-phase connection as of the first quarter in 2014. The three new power supply units provide output currents of 6.25 A (787-738), 12.5 A (787-740) and 20 A (787-742). The units' expanded temperature range of -25 to +70°C, their constant output mode on overload and derating that does not commence until +50°C makes these units an interesting choice for multi-faceted applications - for example, for power supply of consumers in information and automation technology, plant construction, building automation or process engineering. Like their single-phase power supply cousins, the three-phase power supply units can also be connected in parallel. The output voltage can be adjusted between 22 and 28 V using a potentiometer on the front of the unit for exact matching of the power supply to the particular machine or system. The integrated actuating levers make connection of conductors easy and time-saving, as the clamping unit can be opened and closed without using any tools. The CAGE CLAMP connection technology ensures that the clamping unit is always closed completely, regardless of the operator, and that the proper contact force is always applied.
