To establish the operating point, the constant resistance control mode will be used with the resistance value set to be that Amrel Systems PLA1.5K-120-300 the DUT specified operating voltage and current intersect A. The supply will be set to operate in constant current mode at 3A.
The V on function is set to trigger at 40V. To simulate shorted or open circuit diodes or strings, the individual eLOADs can be set to toggle between various resistance values to provide the desired anomalous conditions to observe the operation of the driver under test. Careful consideration should be given to sizing the equipment appropriately for the DUT and type of test to be conducted. Background As energy is transferred from the power supply to the load by means of load leads, a voltage drop across the load leads occurs and may significantly interfere with load regulation.
Remote sensing is a method of compensating for this load lead effect on the output of the power supply. You should also use remote sensing Amrel Systems PLA1.5K-120-300 the measured voltage at the load input power terminals is significantly lower than the voltage measured at the power supply output terminals. The difference in voltage is based on the amount of current and the load lead size and length. Consult the power supply operation manual for maximum voltage drop compensation the sense lines can correct for.

Calculating Voltage Drop To calculate voltage drop of the load lines, first calculate the resistance of the load leads. Then apply Ohms law: Sense line wire gauge should be selected so that there is no greater than a mV drop across the sense lines. Noise and Impedance Effects To minimize noise Amrel Systems PLA1.5K-120-300 or radiation from load circuits, load wires and remote sense wires should be twisted—pair with minimum lead length.
Shielding Amrel Systems PLA1.5K-120-300 the sense leads may be necessary in high noise environments. Even if noise is not a concern, the load and Amrel Systems PLA1.5K-120-300 sense wires should be twisted—pairs to reduce coupling between them, which could impact the stability of the power supply. If connectors are utilized for the power and sense leads, be careful not to introduce coupling between the leads. Ensure that the connector terminals for the sense leads are in adjacent locations, and minimize the physical loop area of the untwisted portions. Ideally, the sense leads should be separated from the power leads and should have their own connector. Twisting the load wires provides an additional benefit in reducing the parasitic inductance of the cable.
This improves the dynamic response characteristics at the load by Amrel Systems PLA1.5K-120-300 low source impedance at high frequencies. Also, with long load wires, the resultant inductance and resistance could produce high frequency voltage spikes at the load because of current variations in the load itself. Automatic power cycling and transient generation is made possible with the use of this GUI program. The GUI output control, measurement and transient screens are shown here. For quality assurance applications, measured voltage, current and VA readings can be logged to disk for documentation and analysis purposes.
All data recorded is time stamped to create a complete history of each test run.
AMREL PLA Series DC eLoad
Up to eight often used front-panel Amrel Systems PLA1.5K-120-300 can be stored in non-volatile memory for quick recall from the PC controller through the interface. If needed, the front panel can be locked out to prevent operator intervention during test runs. The RP and RP offer additional features over the bus such as the ability to select the turn-on or turn-off phase angle of the output voltage. This capability, combined with the peak current measurement function, enables inrush current analysis of a unit under test Applications Transient programming is supported by the GUI program with user defined transient lists of up to steps. Transient programs can be recalled from disk and executed once, continuously or a specified number of times.
Editing functions such as delete and insert make it easy to modify or expand existing programs. Each equipment integrates VSC modules and DSP control boards equipped with all necessary power components, Amrel Systems PLA1.5K-120-300 protections, auxiliary electronics and security elements.
