Safety Guidelines

General Guideline

 Do not place any heavy object on the PEL-

2002/2004.

CAUTION

 Avoid severe impact or rough handling that

leads to damaging the PEL-2002/2004.

 Do not discharge static electricity to the PEL-

2002/2004.

 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-2002/2004 unless

you are qualified as service personnel.

 The equipment is not for measurements

performed for CAT II, III and IV.

(Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. The PEL-2002/2004 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.

WARNING

Battery

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 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.

 Battery type: CR17345 (See page 243).

 When replacing the battery ensure that the

correct make and model are used.

Cleaning the PEL-2000

 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.

PEL-2000 Series User Manual

Operation Environment

Storage 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.

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. THE PEL-2002/2004 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.

 Location: Indoor

 Relative Humidity: < 80%

Disposal

 Temperature: −10°C to 70°C

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.

SAFETY INSTRUCTIONS

Power cord for the United Kingdom

When using the PEL-2002/2004 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:

Green/ Yellow: Earth

Blue: Neutral

Brown: Live (Phase)

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

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.

PEL-2000 Series User Manual

Main Features

Description

The PEL-2002 and 2004 are multichannel programmable DC electronic load mainframes. The PEL-2002 mainframe is able to hold 2 load modules, whilst the PEL-2004 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-2000 series support three operation modes: constant current (CC), constant voltage (CV and CV+CC) and constant resistance (CR). 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

 Supports rack mount installation (PEL-2004)

 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

GETTING STARTED

Interface

 USB

 RS-232C

 GPIB (optional)

Series Overview

The PEL-2000 series comprises of two different Mainframes: the PEL2002 and the PEL-2004. The Mainframes differ by the number of load modules that can be accommodated. The PEL-2002 has two load module slots whilst the PEL-2004 has 4. There are 4 different load module models, the PEL-2020, PEL-2030, PEL-2040 and PEL-2041.

Measurement Overview

The PEL-2000 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. To make tests, Programs and Sequences can be created.

Description

Constant Current Mode (CC)

Constant Voltage Mode (CV)

Constant Resistance Mode (CR)

Programmable Sequences (Prog.)

Sequences (Seq.)

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

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

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

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

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