Unregulated Open Frame Series BVU

PowerVolt's BVU Series of unregulated DC power supplies is the best low cost alternative, where moderate output variations and AC ripple are acceptable. The field selectable input taps allow fine tuning the output voltage to match actual field conditions. The DC output is fused for short circuit protection. For maximum versatility, the output is floating and may be referenced to another low voltage common ground or placed in series with other DC power supplies.

The unregulated open frame BVU Series is recommended for the following applications: DC Motors - Stepping and Servos; Solenoid values; Relays; Lamps and Signal Systems; Input to 3-terminal on-board regulators; Some Floppy Disk Drives.


  • Low cost unregulated DC power supplies
  • Field selectable input taps 103/115/126/207/230/253 VAC for fine-tuning output to match actual field conditions
  • Improved ripple - 3% maximum
  • Fuse protected output
  • Custom grade capacitors
  • Floating output provides versatility for wiring
  • Safety Agency Approvals: UL, CSA, CE marked
