SAFETY INSTRUCTIONS

This chapter contains important safety
instructions that you must follow when operating
the PEL-2002A/PEL-2004A, and when keeping it
in storage. Read the following before operating
the PEL-2002A/2004A to ensure your safety and
to keep the PEL-2000A series in the best possible
condition.

Safety Symbols

These safety symbols may appear in this manual or on the PEL­2002A/2004A.

Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.

Safety Guidelines

General
Guideline

CAUTION

 Do not place any heavy object on the PEL-

2002A/2004A.

 Avoid severe impact or rough handling that

leads to damaging the PEL-2002A/2004A.

 Do not discharge static electricity to the PEL-

2002A/2004A.

 Do not block or obstruct the cooling fan vent

openings.

 Do not perform measurement at circuits directly

connected to Mains (Note below).

 Do not disassemble the PEL-2002A/2004A

unless you are qualified as service personnel.

 The equipment is not for measurements

performed for CAT II, III and IV.

(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
PEL-2002A/2004A falls under category I.

 Measurement category IV is for measurement performed at the

source of low-voltage installation.

 Measurement category III is for measurement performed in the

building installation.

 Measurement category II is for measurement performed on the

circuits directly connected to the low voltage installation.

 Measurement category I is for measurements performed on

circuits not directly connected to Mains.

SAFETY INSTRUCTIONS

Power Supply

WARNING

 AC Input voltage: 115V/230V switchable,

50/60Hz

 The power supply voltage should not fluctuate

more than 15%.

 Connect the protective grounding conductor of

the AC power cord to an earth ground, to avoid
electrical shock.

Fuse

WARNING

 Fuse type: T3.15A/250V

 Make sure the correct type of fuse is installed

before power up.

 To avoid fire, only replace the fuse with the

specified type and rating.

 Disconnect the power cord before fuse

replacement.

 Make sure the cause of a fuse blowout is fixed

before replacing the fuse.

Cleaning the
PEL-2000A

 Disconnect the power cord before cleaning.

 Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid.

 Do not use chemicals or cleaners containing

harsh material such as benzene, toluene, xylene,
and acetone.

Operation
Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

 Temperature: 0°C to 40°C

 Altitude: Up to 2000m

 Transient Overvoltage on the main supply is

2500V.

PEL-2000A Series User Manual

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. THE PEL-2002A/2004A falls
under degree 2.

Pollution refers to “addition of foreign matter, solid, liquid, or

gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.

 Pollution degree 1: No pollution or only dry, non-conductive

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

Storage
environment

 Location: Indoor

 Relative Humidity: < 80%

 Temperature: −10°C to 70°C

Disposal

Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom

When using the PEL-2002A/2004A in the United Kingdom, make
sure the power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the
following code:

As the colours of the wires in main leads may not correspond with the coloured
marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with either the letter E, the earth symbol or coloured

Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked
with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact the
supplier.

This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or user
instructions for details. As a guide, a cable of 0.75mm2 should be protected by a
3A or 5A fuse. Larger conductors would normally require 13A types,
depending on the connection method used.

Any exposed wiring from a cable, plug or connection that is engaged in a live
socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off
the mains power and remove the cable, any fuses and fuse assemblies. All
hazardous wiring must be immediately destroyed and replaced in accordance
to the above standard.

Main Features

Description

The PEL-2002A and 2004A are multichannel
programmable DC electronic load mainframes.
The PEL-2002A mainframe is able to hold 2 load
modules, whilst the PEL-2004A is able to hold 4.
The flexible module configuration allows the
mainframes to either sink multiple loads
independently or large loads when used in
parallel.

The PEL-2000A series support four operation
modes: constant current (CC), constant voltage
(CV and CV+CC), constant resistance (CR) and
constant power (CP). Constant current and
constant resistance mode can operate in either
static or dynamic mode.

Feature Overview

 Flexible operation with removable load modules

 Multiple independent isolated channels

 High performance, up to 5 digit resolution

 High slew rate enabling a high response speed

 High capacity when frame linked

 Different load module types can be used in the

same mainframe

 Dedicated parallel mode.

 Supports rack mount installation (PEL-2004A)

 Supports frame link connections, with up to 4

slave units

 Color LCD display

 120 different sets of programmable sequences

 Accurate load simulation using Sequences

 4 panel setups

 USB flash drive support

Series Overview

The PEL-2000A series comprises of two different Mainframes: the
PEL-2002A and the PEL-2004A. The Mainframes differ by the
number of load modules that can be accommodated. The PEL­2002A has two load module slots whilst the PEL-2004A has 4. There
are 4 different load module models, the PEL-2020A, PEL-2030A,
PEL-2040A and PEL-2041A.

PEL-2000A Series User Manual

Function

Description

Constant Current
Mode (CC)

In constant current mode, the PEL-2002A/2004A
will sink a constant amount of current, regardless
of the voltage.

Constant Voltage
Mode (CV)

Under constant voltage mode, the voltage remains
unchanged, regardless of the current.

Constant
Resistance Mode
(CR)

In constant resistance mode, the resistance load
will remain unchanged as the voltage and current
remain proportional.

Constant Power
Mode (CP)

In constant power mode, the PEL-2000A will
ensure the power consumed is constant.

Programmable
Sequences
(Prog.)

The PEL-2000A series supports programming
sequences. With up to 120 different memory
settings in 12 programs with 10 sequences.

Sequences (Seq.)

Used to create load profiles to accurately simulate
a load. Sequences can be created for each channel.

Parallel Unit
Mode

Parallel Unit Mode enables the PEL-2000A
mainframes to easily use load modules (of the
same type/rating) in parallel. Parallel mode is
used in conjunction with CC or CR modes. CP and
CV mode cannot be used with this mode.

Measurement Overview

The PEL-2000A series has a number of different operating modes
that are completely configurable. All the modes have customizable
Go/NoGo limits, range limits, timers, slew rates, alarms and
protection limits. For parallel loads, there is a dedicated Parallel
configuration mode. To make tests, Programs and Sequences can be
created.
