Safety Summary

The following safety precautions apply to both operating and
maintenance personnel and must be followed during all phases of
operation, service, and repair of this instrument.

Before applying power to this instrument:

 Read and understand the safety and operational information in

this manual.

 Apply all the listed safety precautions.
 Verify that the voltage selector at the line power cord input is

set to the correct line voltage. Operating the instrument at an
incorrect line voltage will void the warranty.

 Make all connections to the instrument before applying power.
 Do not operate the instrument in ways not specified by this

manual or by B&K Precision.

Failure to comply with these precautions or with warnings elsewhere in
this manual violates the safety standards of design, manufacture, and
intended use of the instrument. B&K Precision assumes no liability for a
customer’s failure to comply with these requirements.

Category rating

The IEC 61010 standard defines safety category ratings that specify the
amount of electrical energy available and the voltage impulses that may
occur on electrical conductors associated with these category ratings.
The category rating is a Roman numeral of I, II, III, or IV. This rating is
also accompanied by a maximum voltage of the circuit to be tested,
which defines the voltage impulses expected and required insulation
clearances. These categories are:

i

Category I (CAT I): Measurement instruments whose measurement
inputs are not intended to be connected to the mains supply. The
voltages in the environment are typically derived from a limited-energy
transformer or a battery.

Category II (CAT II): Measurement instruments whose measurement
inputs are meant to be connected to the mains supply at a standard wall
outlet or similar sources. Example measurement environments are
portable tools and household appliances.

Category III (CAT III): Measurement instruments whose measurement
inputs are meant to be connected to the mains installation of a building.
Examples are measurements inside a building's circuit breaker panel or
the wiring of permanently-installed motors.
Category IV (CAT IV): Measurement instruments whose measurement
inputs are meant to be connected to the primary power entering a
building or other outdoor wiring.

Do not use this instrument in an electrical environment with a higher
category rating than what is specified in this manual for this instrument.

You must ensure that each accessory you use with this instrument has a
category rating equal to or higher than the instrument's category rating
to maintain the instrument's category rating. Failure to do so will lower
the category rating of the measuring system.

Electrical Power

This instrument is intended to be powered from a CATEGORY II mains
power environment. The mains power should be 120 V RMS or 240 V
RMS. Use only the power cord supplied with the instrument and

ii

ensure it is appropriate for your country of use.

Ground the Instrument

To minimize shock hazard, the instrument chassis and cabinet must be
connected to an electrical safety ground. This instrument is grounded
through the ground conductor of the supplied, three-conductor AC line
power cable. The power cable must be plugged into an approved three­conductor electrical outlet. The power jack and mating plug of the
power cable meet IEC safety standards.

Do not alter or defeat the ground connection. Without the safety
ground connection, all accessible conductive parts (including control
knobs) may provide an electric shock. Failure to use a properly­grounded approved outlet and the recommended three-conductor AC
line power cable may result in injury or death.

Unless otherwise stated, a ground connection on the instrument's front
or rear panel is for a reference of potential only and is not to be used as
a safety ground.

Do not operate in an explosive or flammable atmosphere

Do not operate the instrument in the presence of flammable gases or
vapors, fumes, or finely-divided particulates.

The instrument is designed to be used in office-type indoor
environments. Do not operate the instrument

iii

 In the presence of noxious, corrosive, or flammable fumes,

gases, vapors, chemicals, or finely-divided particulates.

 In relative humidity conditions outside the instrument's

specifications.

 In environments where there is a danger of any liquid being

spilled on the instrument or where any liquid can condense on
the instrument.

 In air temperatures exceeding the specified operating

temperatures.

 In atmospheric pressures outside the specified altitude limits or

where the surrounding gas is not air.

 In environments with restricted cooling air flow, even if the air

temperatures are within specifications.

 In direct sunlight.

This instrument is intended to be used in an indoor pollution degree 2
environment. The operating temperature range is 0 °C to 40 °C and the
operating humidity 90% relative humidity with no condensation
allowed.
Measurements made by this instrument may be outside specifications if
the instrument is used in non-office-type environments. Such
environments may include rapid temperature or humidity changes,
sunlight, vibration and/or mechanical shocks, acoustic noise, electrical
noise, strong electric fields, or strong magnetic fields.

Do not operate instrument if damaged

If the instrument is damaged, appears to be
damaged, or if any liquid, chemical, or other material gets on or inside
the instrument, remove the instrument's power cord, remove the

iv

instrument from service, label it as not to be operated, and return the
instrument to B&K Precision for repair. Notify B&K Precision of the
nature of any contamination of the instrument.

Clean the instrument only as instructed

Do not clean the instrument, its switches, or its terminals with contact
cleaners, abrasives, lubricants, solvents, acids/bases, or other such
chemicals. Clean the instrument only with a clean dry lint-free cloth or
as instructed in this manual.

Not for critical applications

This instrument is not authorized for use in contact with the human
body or for use as a component in a life-support device or system.

Do not touch live circuits

Instrument covers must not be removed by operating personnel.
Component replacement and internal adjustments must be made by
qualified service-trained maintenance personnel who are aware of the
hazards involved when the instrument's covers and shields are
removed. Under certain conditions, even with the power cord removed,
dangerous voltages may exist when the covers are removed. To avoid
injuries, always disconnect the power cord from the instrument,
disconnect all other connections (for example, test leads, computer
interface cables, etc.), discharge all circuits, and verify there are no
hazardous voltages present on any conductors by measurements with a
properly-operating voltage-sensing device before touching any internal
parts. Verify the voltage-sensing device is working properly before and

v

after making the measurements by testing with known-operating
voltage sources and test for both DC and AC voltages. Do not attempt
any service or adjustment unless another person capable of rendering
first aid and resuscitation is present.
Do not insert any object into an instrument's ventilation openings or
other openings.

Hazardous voltages may be present in unexpected locations in circuitry
being tested when a fault condition in the circuit exists.

Fuse replacement

Fuse replacement must be done by qualified service-trained
maintenance personnel who are aware of the instrument's fuse
requirements and safe replacement procedures. Disconnect the
instrument from the power line before replacing fuses. Replace fuses
only with new fuses of the fuse types, voltage ratings, and current
ratings specified in this manual or on the back of the instrument. Failure
to do so may damage the instrument, lead to a safety hazard, or cause a
fire. Failure to use the specified fuses will void the warranty.

Servicing

Do not substitute parts that are not approved by B&K Precision or
modify this instrument. Return the instrument to B&K Precision for
service and repair to ensure that safety and performance features are
maintained.

Cooling fans

vi

This instrument contains one or more cooling fans. For continued safe
operation of the instrument, the air inlet and exhaust openings for
these fans must not be blocked nor must accumulated dust or other
debris be allowed to reduce air flow. Maintain at least 25 mm clearance
around the sides of the instrument that contain air inlet and exhaust
ports. If mounted in a rack, position power devices in the rack above the
instrument to minimize instrument heating while rack mounted. Do not
continue to operate the instrument if you cannot verify the fan is
operating (note some fans may have intermittent duty cycles). Do not
insert any object into the fan's inlet or outlet.

Use correctly sized wires

To connect a load to the power supply, use a wire diameter large
enough to handle the maximum continuous output short-circuit current
of the power supply without the wire overheating.

For continued safe use of the instrument

 Do not place heavy objects on the instrument.
 Do not obstruct cooling air flow to the instrument.
 Do not place a hot soldering iron on the instrument.

2 Getting Started

Before connecting and powering up the instrument, please review and
go through the instructions in this chapter.

2.1 Input Power and Fuse Requirements

Input Power

The supply has a universal AC input that accepts line voltage input
within:

AC Input: 170 V – 265 V (10% output de-rated when operating below

190 VAC)

Frequency: 47 Hz – 63 Hz

Before connecting to an AC outlet or external power source, be sure
that the power switch is in the OFF position and verify that the AC
power cord, including the extension line, is compatible with the rated
voltage/current and that there is sufficient circuit capacity for the power
supply. When the AC input voltage is lower than the full-load voltage,
which is 200VAC, the supplies will activate an inner over temperature
protector and cut off the output in response to the condition. To ensure
that the entire test process can be completed smoothly, confirm that
the input AC voltage is within the specified range. Once verified,
connect the cable firmly.

9

The included AC power cord is safety certified for this
instrument operating in rated range. To change a cable
or add an extension cable, be sure that it can meet the
required power ratings for this instrument. Any misuse
with wrong or unsafe cables will void the warranty.

SHOCK HAZARD:

The power cord provides a chassis ground through a
third conductor. Verify that your power outlet is of the
three-conductor type with the correct pin connected to
earth ground.

Follow the instructions below to connect the AC power cable to the AC
input of the power supply in the rear panel.

1. First, connect the input receptacle (green terminal block) of the
cable to the input terminals of the power supply.

2. Align the power cord housing mounting holes on the left and
right side to the screw holes on the power supply.

3. Use only the included screws to fasten and secure the cable
housing assembly.

10

Do NOT plug the AC power cord into the wall socket
prior to connecting ALL three AC power wires to the rear
panel and securely mount the safety metal housing over
the input receptacle. Doing so may create a shock
hazard.

Connection of this power supply to an AC power source
should be made by a qualified electrician or other
qualified personnel. Incorrect wiring may damage the
power supply or cause a fire hazard

Figure 2.1 – AC Power Connection Diagram

Refer to the descriptions below to connect the other end of the AC
power cord to the AC distribution panel.

Connect the three terminals black to line (L), white to neutral (N), and
green to ground (G) on the other end of the power cord to your AC
distribution panel.

11

Any disassembling of the case or changing the fuse not
performed by an authorized service technician will void
the warranty of the instrument.

Figure 2.2 – AC Power Cord

Fuse Replacement

This power supply does not require a fuse that is user replaceable.
There is an internal fuse, in which if blown, may indicate a malfunction
in the unit. In this event, contact B&K Precision.

2.2 Rackmount Installation

The PVS series power supplies are designed to fit in a space of two rack
units (2U) and can be mounted in a standard 19-inch rack panel or

12

cabinet. Rack mount brackets must be assembled before mounting the
unit in a rack. Refer to the following figure to assemble the rack mount
brackets.

Figure 2.3 – Rack Mount Bracket Assembly

2.3 Output Connections

The main DC output terminal is a screw type terminal block located in
the rear panel.

Due to the high current rating of the power supply, proper wire sizes are
necessary for safe connectivity and to prevent wires from overheating.
Refer to the below table as a reference for proper wire sizes according

Before connecting wires to the output terminals, turn
OFF the power supply to avoid damage to the
instrument and the device under test (DUT). For safety,
load wires must have a wire gauge size large enough to
prevent overheating when the power supply operates at
maximum short circuit output current. It will also
prevent large voltage drops from resistances in the
wires.

SHOCK HAZARD:

Hazardous voltages may exist at the outputs and the
load connections when using a power supply with a
rated output greater than 40V. To protect personnel
against accidental contact with hazardous voltages,
ensure that the load and its connections have no
accessible live parts. Ensure that the load wiring
insulation rating is greater than to the maximum output
voltage of the power supply.
