Page 61: Operating Mode Description
GETTING STARTED Operating Mode Description There are three basic operating modes: constant current (CC), Constant Resistance (CR), and Constant Voltage (CV/CV+CC). All channels operate using any of the modes. Each mode has a number of configurable options including slew rate, levels, protection modes, Go/NoGo and extensive save options.
Page 62 PEL-2000 Series User Manual There are two selectable ranges for constant current Range mode: high and low range. Low range has a higher resolution, but a lower range. If the current exceeds the Low Range, High range must be used. Static Functions Static mode tests the stability of the voltage output from a power source.
Page 63 GETTING STARTED The slew rate is the rate at which the current will Slew rate increase to a set level. There are two slew rates: rising slew rate & falling slew rate. In CC mode the slew rate is defined as A/uS. As can be seen above, the rising and falling slew rate need not be the same.
Page 64 PEL-2000 Series User Manual CC Mode: Static:Go/NoGo Current Load Current NoGo NoGo Voltage GO is specified as between the Low and High Go/NoGo limits. NoGo is specified as outside the Go/NoGo limits.
Page 65: Constant Resistance Mode
GETTING STARTED Constant Resistance Mode In Constant Resistance Mode the load units will Background linearly sink current and voltage to match a set resistance. CR mode has two different values (single load modules), two different ranges and rising and falling slew rates. Like CC mode, Constant resistance mode supports both dynamic and static loads.
Page 66 PEL-2000 Series User Manual Single Load Module CR mode supports Dynamic loading. Dynamic Dynamic load has two resistance levels (Level 1&2), and two Functions timers (Timer 1&2) to switch between the resistance levels. Rising and falling slew rates can be set to determine the speed at which the load generator switches between load levels.
Page 67 GETTING STARTED...
Page 68: Constant Voltage Mode
PEL-2000 Series User Manual Constant Voltage Mode In Constant Voltage Mode the load units will sink Background current whilst keeping the voltage constant. Single channel load modules support 2 values (A Value, B Value) and have an adjustable cut-off current limit. Dual channel load modules only have A value.
Page 69 GETTING STARTED CV Mode Voltage A value B value Time When using CV mode, a current limit can be set for CV + CC CV + CC mode. When the voltage input is greater than A Value (load voltage) then the channel will operate in CV mode if the input current is less than the current limit.
Page 70 PEL-2000 Series User Manual Response Speed Response speed can be set to fast or slow. Fast response and slow response is determined by the load module specifications. Slow response speeds are suitable for large loads as quick current changes will induce induction which can cause large voltage drops.
Page 71: Run Program
GETTING STARTED Run Program The Program function on the PEL-2000 series Background supports a total of 12 different programs at any one time with 10 sequences to each program. Up to 12 programs can be chained together. The Program function is able to create a number of Go/NoGo tests.
Page 72 PEL-2000 Series User Manual P/F-Time Off – 0.1 ~ (On-time+Off-time)-0.1 Short Channel CH1 ~ CH8 Sequences are run sequentially to create a Program. Program There are 10 Sequences in each Program. If less than 10 Sequences are desired for a Program, any additional Sequences can be skipped (not run).
Page 73 GETTING STARTED Go/NoGo Results If Go/NoGo limits have been configured, the Pass/Fail results for each channel will be displayed for all the sequences and programs.
Page 74: Sequence
PEL-2000 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 75 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 76 PEL-2000 Series User Manual If more than one Sequence is programmed on the On end load mainframe, the On End Load function allows a Sequence to configure its load on or off at the end of its sequence until the last sequence ends. After the last sequence ends, all loads are turned off.
Page 77 GETTING STARTED The Channel Duration Time Setting feature allows Channel Duration Time Setting the point time duration of one Sequence to be imported by another Sequence. If the receiving sequence doesn’t have enough points, more will be created (without values). For example, the sequences for CH1 and CH2 are shown below.
Page 78: Parallel Dynamic Loading
PEL-2000 Series User Manual Parallel Dynamic Loading The PEL-2000 series of DC electronic loads support Background 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 82 PEL-2000 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 83 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 84 PEL-2000 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 182) at run time.
Page 85: 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 86 PEL-2000 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 Vor A” is the rating voltage/current of the load module. Current Monitor The load current input can be externally monitored using the IMON pin of a channel control connector.
Page 87 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 88 PEL-2000 Series User Manual A load is turned on when Load On input is set to Turning on the Load On (active low). A load is turned off when the 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.
