Has high power density design, subversive high power electronic load is big, the concept of mobility, can save a lot of laboratory space, at the same time can easily solve the automatic test system updating electronic load space issues.In addition, 63200 a defined also provides four groups of commonly used shortcut keys, let users can more quickly into the required operating mode.

Clear graphical options, can let users easier to use 63200 a series of basic load function and advanced function by the graphical, users can through the knob, the direction key to select the desired function.Graphical options text shown in abbreviation, provide full description screen above the other, even without the user manual, also easy to get started.

63200 a series of constant voltage, constant current, constant resistance and constant power mode, by these operating modes can be to meet a wide range of test requirements., for example, constant current and resistance model for voltage source test, the object under test can be confirmed in different load cases, the object under test whether the output voltage remains stable output.For battery charger or pile, the constant voltage mode can change the output voltage of the charger or pile, in order to ensure that the charger or pile in setting the output voltage of the correctness of the charging current.When the object under test is the battery, the electronic load can be transformed into analog electronic equipment load behavior, and many of the battery discharge application, power consumption, and so on and so forth can be borrowed by the electronic load simulation analysis of behavior to the battery, and constant power mode is analog electronic equipment, the choice of behavior.

Series 63200 a has an intelligent master/slave control mode, when the load power demand, all with voltage specification models, are available through the parallel mode (master/slave control) to achieve the required current and power.When set into the master/slave control mode, all set to the master/slave control the electronic load can be a single load, users only need programming load current on the main load, the load automatically calculating the current distribution to the other from the load, and so can greatly simplify user's operation steps.Full range of models can be integrated to 19 "standard rack wide, to save space, with no control panel for 600 v and 1200 v from the machine needs to match the host of a control panel is used.63200 a at the same time equipped with USB interface (standard), GPIB, Ethernet and CAN BUS interface (optional), users CAN through these interfaces for the automatic test of remote control and other applications.

63200 a series have sine wave load current, and allows users to set bias load current value (I_DC), lugging sine wave (I_AC) and the sine wave Frequency values (Frequency), the sine wave load the lowest not less than zero amps.The sine wave, load current function can be used in the D/D, and server power supplies and dc resistance (DCIR) fuel cell test.

In the era of rapid, electronic components are in the direction of the high-speed operation of design, as a result, the power supply components for the transient signal and dynamic response performance requirements, is much higher than in the past.To meet the requirements of the test application and, 63200 a series offers high speed, programmable dynamic load resistance (CCD dynamic current load and dynamic load CRD), the dynamic frequency sweep scanning (sweep) model, etc.Shown below for programmable parameters: set the current high/low bit, T1 / T2, rate of climb/sink rate and the number of executions.63200 a series of continuous changes in load current, internal monitoring mechanism and route to make current waveform distortion degree minimized, 150 v model of current climbing minimum response time for 10 mu s, dynamic change can be as high as 50 KHZ.

In addition to the above basic parameters can be set, but also allows the user to set a new time of repetitions, the range of 1-65535.This feature is very suitable for application in the test D/D converter and instantaneous large current degree of tolerance of the battery.

There will be many capacitance on the motherboard, to avoid the server power supply when the power switch on the instant of capacitance charging on the motherboard, and surge current lead to trigger the power supply of the overcurrent protection mechanisms to smooth start up, so the power supply need a capacitive load on test, for 63200 a series against the test requirements, provide constant impedance load patterns.

Constant impedance load mode is different from the rated current and rated power of the load, constant impedance model which simulated the actual impedance, impedance, capacitive reactance and load to load, therefore, load current can approach the real situation.The waveform, simulation of switching power supply to the capacitive load boot test voltage and current waveform.

63200 a series with the industry precision measurement accuracy, has three load rank, to a model 63206 a - 150-600 as an example, the voltage 16 v / 80 v / 150 v three gear, meet the server power supply or communication power supply (12 v, 48 v, 54 v) test requirements;Current 60 A / 300 A / 600 A third gear, it can provide different applications current setting and measurement error smaller gear, the other built-in high precision A/D converter, voltage, current, power measurement specifications of voltage is 0.015% + 0.015% f.s., current 0.1% 0.1% + 0.04% + 0.04% f.s and power f.s precision.For the measurement of the high precision of the measuring efficiency is an indispensable function of the object under test.

Power supply design, in order to ensure the safety of users and reduce the damage rate of power supply, overcurrent protection and power protection mechanism is often need to be taken into consideration and design, in 63200 a current with a power test, can provide users to set the step order current step or order power for power supply current or power protection test, and to determine the electronic load test result is Pass or Fail, in the process of testing value maximum power (Pmax), also can automatically capture and display on the monitor, can help users through the oscilloscope to verify that the design of over current and power mechanism is correct, but also reduce the number of test time for users.

Bring over current testing

In addition to general rated current, rated voltage, rated power and rated resistance load patterns, when lugging around arbitrary waveform, the traditional way is through the computer will be stored waveform through DAQ card in advance or simply through the arbitrary waveform generator send waveform to electronic load tensile load, thus achieve the purpose of lugging around arbitrary waveform, as shown in the figure below.

However 63200 a series offers a more convenient alternative to - the user custom waveform, can simulate the real load current, the oscilloscope can be correspond to the actual current waveform data or to edit current waveform, easily through graphical operation software of the waveform is stored in 63200 - a series of internal Flash memory (Flash), you can pull a load user defined by arbitrary waveform, can save the DAQ card or the cost of the waveform generator, as shown in the figure below.63200 a series, a total of 10 groups of waveform storage space can be saved, up to 1.5 million waveform points, enough to provide the required test.

At the same time, in addition, in the real current 63200 a series also provides lugging around what happened in the process of the maximum peak voltage is negative, the user does not need to through the oscilloscope to observe the voltage change, greatly saved by oscilloscope to confirm the voltage peak time.

For battery discharge test, 63200 a offers users three discharge modes: constant current, constant resistance and constant power mode, and through set cut-off voltage and stop time (1 seconds to 100000 seconds), stop the electronic load can correct load, make sure the battery will not damaged by excessive discharge.In addition, in terms of measurement, to measure the discharge of the battery power (WH, AH), and total discharge time.For example: when the press Load ON began to pull, 63200 a series of internal timer will start counting, until the battery voltage drop until set voltage or by pressing the Load OFF stop tensile Load, the timer stop counting.The battery discharge test function can be used in super capacitor discharge time testing and other similar applications.
