Unregulated Open Frame DC Power Supplies
  • 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
  • Computer grade capacitors
  • Floating output provides versatility for wiring
  • Safty Agency Approvals BVU Series:
       -UL 1950, third edition, File #E181899
       -CSA, C22.2 No.950, File #E181899
       -CE Marked
The 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.

Schematics

Schematic shows transformer taps provided for approx. +/-10% output voltage adjustment. Typical full load output voltage at 115VAC input using taps 1 and 3. For 10% higher output voltage use taps 1 and 2. For 10% lower output voltage use taps 1 and 4.
