The 805405-1 unit is an SF3000 Panel-Mounted Single-Phase Field Power Module that was made by Reliance Electric. This product has since had its production stopped by its original manufacturing company, but AX Control makes an effort to supply this device for our customers and may have it in stock right now. The 805405-1 Field Power module’s availability in our stock is listed on this page, but you can also call or email us during our business hours.
The 805405-1 Field Power module is designed to bring the DC motors within the AutoMax series the means for adjustable-voltage, current-regulated field excitation processes. To do this, the 805405-1 Field Power module is used along with a three-phase Armature Power module that are both connected to the same PMI rack. The 805405-1 Field Power module’s SCR power bridge is designed to be operated using the AutoMax Programming Executive software.
The 805405-1 Field Power module has a power rating of 15 Output Amps and an AC Input Voltage range of 120 to 460 VAC with a non-reversing bridge type. In addition to that, the 805405-1 Field Power module has an electrically isolated power cube, which has its own dv/dt protection, and internal AC line fuses. There is also a self-firing clamp which is used for providing protection against the event of an inductive voltage kick that results from current interruption. The 805405-1 Field Power module’s rectifier consists of a total of four SCRs, all of which are configured for used in a full-wave bridge. An isolation transformer is an optional component component for this module.
