The BVU Series
Specifications
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.
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% r.m.s. maximum at nominal 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.
Applications
• DC motors - stepping and servos
• Solenoid valves
• Relays
• Lamps and signal systems
• Input to 3-terminal on-board regulators
• Some floppy disc drives

studs for motor drivers

The StepperPower™
The StepperPower™, Series PV5000 and BVU6000, is an
integral power supply module especially designed to
operate stepping motors. Motor and logic power supplies are both incorporated in one package (when applicable). Models are available to drive one or two motors.
The single driver models are assembled on an L-shaped
chassis and threaded (#6-32) PEM nuts to mount motor
driver. The dual driver models feature a U-shaped chassis wire threaded (#6-32) PEM nuts on both sides to
mount two motor drivers. This makes it an integral
space saving unit eliminating the need for installing and
wiring different pieces.
Integral motor and logic power supplies
The motor and logic power supplies required to operate
the stepping motors and associated control logic are
both incorporated in one unit. This eliminates the need
to install and wire two different power supplies to a separately mounted driver modules. The motor power is
unregulated DC voltage; while the logic power is a fully
regulated DC output that is maintained within tight regulation (±0.25V) over a large range of input AC voltage.
Models to drive one or two motors
The single motor drivers are commonly used. However,
in a multi-axis control application, the dual driver
models are a very cost effective and space saving alternative. In the single as well as dual driver models, the voltage and current ratings are provided to allow maximum
motor torque without exceeding the safe operating voltage and current limits. When operating two drivers from
one power supply, the effect of regenerative energy must
be considered to assure safe operation of the drivers.

Space saving compact power module
provides mounting studs for motor drivers
The StepperPower™ modules, series PV5000 and
BVU6000, feature a transformer with high efficiency and
excellent regulation that assures a compact physical
size. They are assembled on space saving L- or U- shaped
chassis. PEM nuts for mounting the driver modules are
provided on one side of the L-bracket and on both sides
of the U-chassis. Once the drivers are mounted on the
power module, they become fully self-contained units
without any need of external components. The outputs
are lead wires that can be wired directly to the screw
terminal connector available on the driver modules.
This simplifies the installation and saves wiring time.
Input taps to match actual line voltages
As the motor power is unregulated, it tends to vary with
the input line voltage. For example, if a high line is
applied at the 120VAC tap, the motor output voltage may
exceed the safe operating limit of the driver and cause
damage. The taps are provided so that in high line locations, the output voltage can be kept within the safe
operating limit by using the corresponding tap. The
logic power is regulated and is not affected by the input
line voltage over a wide range (95V AC to 135V AC when
connected to 120V AC tap).
Custom designs to match other applications
PowerVolt will design any other custom units to match
your application. Please call us for quotes.
