Page 12: Main Features
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.
Page 13: Series Overview
GPIB (optional)  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 PEL- 2002A 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.

This saves the hassle of configuring each channel individually. Parallel Configuration is only supported under CC and CR mode.
Page 76 PEL-2000A Series User Manual Consider 3 load modules set to CC mode in CC Example Parallel. In CC mode the total current for all units is the sum of each unit. Total    For example, to set a total load current of 90A, the Current Level setting in Para mode would be 90A, whilst it would be 30A in Sync mode.

Page 78 PEL-2000A Series User Manual Each Sequence has a number of configuration options that apply to all the channels equally. Sequence Item Description Memory Loads the channel settings for each load module Range: M001~M120 Sets the running configuration for the current sequence.

Page 79 GETTING STARTED If less than 10 Sequences are desired for a Program, any additional Sequences can be skipped (not run). Program 1 Sequence (P01) Sequence 2 & 3 are skipped. Any of the 12 programs can be chained together to Program Chain create a Program Chain.
Page 80: Sequence
PEL-2000A Series User Manual Sequence The Sequence function is used to create high Background resolution load simulations. Each Sequence can be configured to create a unique load profile to accurately simulate loads in real time. Sequences are only applicable for CC (Static) and CR (Static) modes.
Page 81 GETTING STARTED Up to 120 points can be used with each Sequence. Points Each point can have a different duration, slew rate and value. A new point can be inserted or deleted at any stage of a Sequence. Any new points that are inserted will have a value averaged from its neighbors as default.
Page 82 PEL-2000A Series User Manual If more than one Sequence is programmed on the On End Of Seq. mainframe, the On End Of Seq. function will hold function the load current (of the selected sequence) to a designated value until all the other sequences have finished running.

GETTING STARTED OCP Test Automation The OCP test function creates an automatic test to Background test the over current protection of power supply products. See page 179 for operation details. This test will test to see when the over current protection of a power supply is tripped and return the measurements for the voltage and current when the over current protection was tripped.
Page 86: Parallel Dynamic Loading
PEL-2000A Series User Manual Parallel Dynamic Loading The PEL-2000A series of DC electronic loads Background support parallel dynamic loading. This simply means that when the load modules of a mainframe are connected in parallel and set to dynamic mode, they can perform dynamic tests synchronously following the same clock.
Page 87: Configurations Description
The Configuration Description section describes what the different configurations are used for and how they can be relevant to different operations. Protection Modes The PEL-2000A series include a number of Background protection modes: Over Current Protection, Over Voltage Protection, Over Power Protection, Under voltage protection and Constant Power Protection.
Page 88 PEL-2000A Series User Manual When a load unit is operating in CR, CV or CP Over Current mode, the unit may need over current protection to Protection prevent excessive current being sunk. Over current protection stops the load from sinking more current than its recommended limit which can cause damage to the unit.
Page 89: Operating Configurations
OPP is tripped power will cease to be sunk. Reverse voltage protection prevents reverse voltage Reverse voltage damage to the PEL-2000A series up to the specified Protection rating. When Reverse voltage protection has been tripped an alarm tone will sound until the reverse voltage is removed.
Page 90 PEL-2000A Series User Manual Von Voltage is the voltage limit at which the load Von Voltage will start to sink current. There are two operation modes for Von Voltage: Von latched: ON and Von latched: OFF. Latched: ON will sink current when Von has been tripped, and will continue to sink current even if the voltage drops below the Von Voltage.
Page 91 GETTING STARTED When short mode is on, the load unit can simulate a Short short circuit. Shorting can be individually set for each channel when programming sequences. To initiate a short circuit manually, the short key is used. It can be used at any time during an operation.
Page 92 PEL-2000A Series User Manual Load Delay time is used to delay activating a load Load D-Time (up to 10 seconds) after the load key has been pressed. However the Load D-Time setting will only work for loads that are initiated manually or when the PEL series mainframe is configured to Auto load (page 217) at run time.
Page 93: Channel Control
GETTING STARTED Channel Control External channel control is used with the Channel Background Control connectors. Each channel control connector can activate each load, monitor voltage and current and has an external voltage reference input. The voltage and current monitors output 0~100% of the rated current/voltage as a voltage of 0~10V.
Page 94 PEL-2000A Series User Manual To determine the Percent Rating (voltage or current load input), use the following formula; External Voltage   Load Input Rating VorA   Where “Rating V or A” is the rating voltage/current of the load module.
Page 95 GETTING STARTED Voltage Monitor The input voltage, like the load input current can be externally monitored with the channel control connectors. The VMON pin of the channel control connector outputs a voltage of 0~10V to represent the load input voltage as a percentage (0~100%) of the rating voltage.
Page 96 PEL-2000A Series User Manual A load is turned on when Load On input is set to Turning on the On (active low). A load is turned off when the Load Load On input is set to Off (active high). When a load is turned on from the channel control interface, the load can be turned off from the mainframe, local module and via remote control.
