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
● Safety Agency Approvals BVU Series:

The BVU Series
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.
Specifications
AC input:
115/230VAC, 50/60Hz nominal.
Field selectable taps for ±10%. High line tolerance on
voltage is +10%
DC Output:
Floating fixed output at full load ratings
(see table).Transformer taps provided for approx. 10%
output voltage adjustment.
Ripple:
3% rms maximum at normal line and full rated
load.
Operating Temperature:
0-50°C(Derate 2% per °C
to 70°C)
Overload and Short Circuit Protection:
Fused
output It should be noted that the fuse is not necessarily
direct in line with the output. In most models the fuse is
prior to the output capacitor and in case of a short
circuit, the capacitor energy will be discharged into the
load even if the fuse has opened.
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.
Applications
● DC Motors
- Stepping and Servos
● Solenoid values
● Relays
● Lamps and Signal Systems
● Input to 3-terminal
on-board regulators
● Some Floppy Disk Drives
