Page 60: Operating Mode Description
PEL-2000B 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 61 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 62 PEL-2000B 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 63: 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 64 PEL-2000B 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 65: 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 67 The PEL-2000B 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 68: Constant Power Mode
PEL-2000B 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 69 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 76 PEL-2000B 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 81: Parallel Dynamic Loading
OPERATING DESCRIPTION Parallel Dynamic Loading The PEL-2000B 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 82: 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-2000B 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 83 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.
