Page 62: Operating Mode Description
PEL-2000A Series User Manual Operating Mode Description There are four basic operating modes: constant current (CC), Constant Resistance (CR), Constant Voltage (CV/CV+CC) and Constant Power (CP). 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 63 OPERATING DESCRIPTION Static Functions Static mode tests the stability of the voltage output from a power source. Single channel load modules can have two 2 current levels A (A Value) & B (B Value). A & B have the same range. Pressing the A/B key on the module load will cycle through the A and B states.
Page 64 PEL-2000A Series User Manual 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.
Page 65: Constant Resistance Mode
OPERATING DESCRIPTION CC Mode: Dynamic:Go/NoGo Current Level 1 Level 2 NoGo Voltage GO is specified as between the Low and High Go/NoGo limits. NoGo is specified as outside the Go/NoGo limits. Constant Resistance Mode In Constant Resistance Mode the load units will Background linearly sink current and voltage to match a set resistance.
Page 66 PEL-2000A Series User Manual Resistance Range There are two ranges: High and Low. The Low range is used for low voltage ranges, whilst the High range uses high voltage ranges. The current range always remains in High range, regardless of the selected resistance range.
Page 67: Constant Voltage Mode
OPERATING DESCRIPTION The rising and falling slew rate (A/uS) determines Slew Rate the speed at which the load levels change from A to B Value (Static mode) or from Level1 to 2 (Dynamic mode) and vice versa. Go/NoGo is also supported. Center, High and Go/NoGo Low limits can be set as either percentages or voltage values.
Page 68 PEL-2000A Series User Manual CV Mode Load Current Load Input Voltage Two voltage levels can be set: A & B (single Voltage levels channel load module). CV Mode Voltage A value B value Time When using CV mode, a current limit can be set CV + CC for CV + CC mode.
Page 69 The PEL-2000A series will try to rectify any voltage drops. However if voltage drops are too large, they may cause the load to go into oscillation.
Page 70: Constant Power Mode
PEL-2000A Series User Manual Constant Power Mode In Constant Power Mode the load units will Background ensure a constant power load for the power supply. Single channel load modules support 2 values (A Value, B Value) and have an adjustable cut-off current limit.
Page 71 OPERATING DESCRIPTION When using CP mode, a current limit can be set CP + CC for CP + CC mode. When the constant power current is less than current limit, the channel will operate in CP mode. When the constant power current exceeds the current limit, the channel will operate in CC mode.

Page 77: Sequence
OPERATING DESCRIPTION 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 78 PEL-2000A Series User Manual 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 79 OPERATING DESCRIPTION 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.
Page 80 PEL-2000A Series User Manual As can be seen above, a trigger sequence signal is output for every rising edge point. The Trigger In setting allows a sequence to start Trig In after a trigger (Trig Out) has been received via the frame link connector.

The PEL-2000A series also has a user-defined OCP setting in the event that the power supply OCP fails.
Page 83: Parallel Dynamic Loading
OPERATING DESCRIPTION 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 84: 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 85 OPERATING DESCRIPTION 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 set. Over current protection stops the load from sinking more current than its recommended limit which can cause damage to the unit.
Page 86: Operating Configurations
PEL-2000A Series User Manual Reverse voltage protection prevents reverse Reverse voltage voltage damage to the PEL-2000A series up to the Protection specified rating. When Reverse voltage protection has been tripped an alarm tone will sound until the reverse voltage is removed.

Page 88 (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-2000A series mainframe is configured to Auto load (page 210) at run time. The Response setting sets the bandwidth of the Response load to 1kHz (normal) or 100kHz (fast).
Page 89 OPERATING DESCRIPTION The step resolution range is dependent on the load Step Resolution module and the range: Range Max resolution: Module dependent, see page 197 Min resolution: Module dependent, see page 197 When short mode is on, the load unit can simulate Short Key a short circuit.
Page 90: Channel Control
PEL-2000A Series User Manual 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 91 OPERATING DESCRIPTION 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. Current Monitor The load current input can be externally monitored using the IMON pin of a channel control connector.
Page 92 PEL-2000A Series User Manual 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.
