PAGE 33
GETTING STARTED Current ∆I Voltage time ∆T E Min. V time The diagram above shows how changes in current can affect voltage. Limiting Load line inductance Load line inductance can be reduced in two ways. 1. Ensure load wires are as short as possible and twist the positive and negative load wires together. 2. Current change can be limited by limiting the slew rate or response speed when switching in CR and CC mode.
PAGE 34
PEL-3000 User Manual Load Wire Connections Description The PEL-3000 has input terminals on both the front and rear panels. Follow the procedures below for all load connections. Please adhere to the following precautions to ensure your safety and to protect the unit from damage. Connection When connecting the PEL-3000 to the DUT, make sure that the polarity of the connection between the DUT and the unit matches. Ensure that the maximum input voltage is not exceeded.
PAGE 35
GETTING STARTED Using the Front Panel Input Terminals The front panel input terminals feature polarity-distinct caps and accept M6 sized crimped terminals. Description The front panel input terminals on the PEL-3000 are physically connected to the rear panel terminals. Caution Steps 1. Turn the power off from the rear panel or put the unit into standby mode. 2. Turn the power off from the DUT. 3.
PAGE 36
PEL-3000 User Manual Using the Rear Panel Input Terminals The rear panel input terminals accept up to M8-sized crimped terminals. The rear terminals come with a load input terminal cover for safety. Description The front panel input terminals on the PEL-3000 are physically connected to the rear panel terminals. Caution Steps 1. Turn the power off from the rear panel or put the unit into standby mode. 2. Turn the power off from the DUT. 3.
PAGE 37
GETTING STARTED Using the Terminal Cover Description The rear panel terminal cover should be used to prevent electric shock. The rear panel terminal covers should always be used when connecting a load to the rear panel terminals. As the front panel and rear panel terminals are physically connected, the terminal cover should also be used as a safety measure when a DUT is connected to the front terminals Caution Ensure the power is off before making any connections to the PEL-3000.

PAGE 40
PEL-3000 User Manual Remote Sense Remote sense can be used to help compensate for long cable length. The longer the cable, the higher the potential resistance and inductance, therefore a short cable is best. Twisting the cable can help reduce induced inductance and using the Vsense terminals compensates the voltage drop seen across the load leads, especially leads with higher resistance. This is useful when used in CV, CR or CP mode. Description Steps 1.

PEL-3000 User Manual Sequence The PEL-3000 supports both programs and sequences. The essential difference between programs and sequences is that programs can use different operating modes for each step while sequences use the same operating mode throughout the whole sequence. In effect sequences are used to create complex load simulations. There are two different types of Sequences, Normal Sequences and Fast Sequences. Normal sequences can define the execution time and slew rate of each step.

OPERATION Save Recall The PEL-3000 can save and recall system settings, preset data, memory data, Go-NoGo settings as well as normal and fast sequences to internal memory or to USB. File Structure Description The PEL-3000 file system can save files to internal memory (Media|Memory) and external memory (Media|USB). To save or recall Memory, Setup or Preset data, the PEL-3000 uses a three tier system where files are saved or recalled in the following order: Active settings <> Internal memory <> USB.
PAGE 122
PEL-3000 User Manual For example: To load Preset Data P7 from USB, you must first load Preset Data P0~P9 to internal memory, then from internal memory load Preset P7 to be the active preset setting. For normal and fast sequences however, files can be saved or recalled directly to/from USB memory. File Types Memory Data Memory data contains general settings and is used for creating programs.

PEL-3000 User Manual Analog Control The Analog Control subsection describes how to use the J1 Frame Control Connector for voltage or resistance control. The J2 connector, located under the J1 connector is used for parallel control. See page 181 for the details J1 and J2 connectors. J1 Connector Overview Description The J1 External Control Connector is a standard Mil 20 pin connector (OMRON XG4A IDC plug). The connector is used for all analog control. The pins are used to determine what mode is used.
PAGE 137
EXTERNAL CONTROL External Voltage Control - Overview Background External voltage control of the CC, CR, CV and CP mode is accomplished using the J1 connector on the rear panel. An input voltage of 0~10V corresponds to 0% ~ 100% of the rated current (CC mode), rated voltage (CV mode), or rated power (CP mode). For CR mode, 0V ~ 10V corresponds to the maximum resistance ~ minimum resistance.
PAGE 138
PEL-3000 User Manual Caution When using external voltage control, make sure no more than ±11V is applied across pins 1 and 3. Exceeding this voltage could damage the PEL-3000. Exceeding 11.8V will cause an EXT.OV alarm message to appear which also will reset the voltage output to 0V until the external voltage is reduced back down below 11.8V. Use caution when using pin 3. Pin 3 is directly coupled to the negative input terminal.

PEL-3000 User Manual External Resistance Control – Operation Description External resistance control can be used to control the current, voltage, resistance and power for CC, CR, CV and CP modes. Configuration for each operating mode is the same. CC Mode Proportional Control: Input current = rated current × (external resistance/10). Inverse Control: Input current = rated current × (1 - external resistance/10).

Input Power Inverse control Proportional control Rated Power 0Ω The inverse configuration is recommended for safety reasons. In the event that any of the cables become accidentaly disconnected, the current/voltage/power input will drop to the minimum.

Set the Control to R for proportional control or to Rinv for inverse control.  The J1 connector is now ready for external resistance control. Turning the Load On using External Control Description The load can be turned on and off with an external switch connected to pins 7 and 12 of the J1 connector. Pin Inputs Pin 7 of the J1 connector is internally pulled up to 5V with a 10kΩ resistor when the switch is open.
PAGE 146

Pin out The Load On Status pin is a photocoupled opencollector output. 13 17 Photocoupler input: 30V max, 8mA, max. External Control of the Range Description The range for the present operating mode can be externally controlled when the current range is set to high range. The range is changed using pins 8, 9 (Range Cont 1 &2) and 12 (A Com) of the J1 connector.
PAGE 148

PEL-3000 User Manual External Control of the Alarm Description An alarm can be activated/deactivated using external control with the J1 connector (pins 10, 12). When the alarm is activated, an EXT.AL message is also output. The alarm can be activated by an external device or by a parallel slave unit. The alarm is activated by sending a low-level signal. The operating threshold level is TTL. Pin Inputs Pin 10 is internally pulled up to 5V with a 10kΩ resistor when open.
