Unregulated Open Frame DC Power Supplies

Series: BVU

RoHS

● 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

● Safety Agency Approvals BVU Series:

− UL 1950, third edition, File #E181899.

− CSA, C22.2 No.950, File #E181899.

− CE Marked.

The BVU Series

The BVU Series of unregulated DC power supplies is the

Specifications

AC input: 115/230VAC, 50/60Hz nominal.

best low cost alternative, where moderate output variations Field selectable taps for ±10%. High line tolerance on

and AC ripple are acceptable. The field-selectable input taps voltage is +10%

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.

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)

Applications

● DC Motors - Stepping and Servos

● Solenoid values

● Relays

● Lamps and Signal Systems

● Input to 3-terminal on-board regulators

● Some Floppy Disk Drives

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.
