Note with caution that the peak current limiter may allow overshooting, depending on the load, and therefore may not achieve the peak current value as set. For an inductive load, operation of the limiter can cause an output overvoltage, triggering the overvoltage protection function. In this case, the peak current limiter settings (positive and negative) should be reduced.

If the output current or frequency suddenly increases, due to an output short, etc., the limiter response may not be quick enough, so the output overcurrent protection function may be triggered.

CAUTION

3.4.7 Using limiter functions

a) Using current limiter

The APS-1102A includes a peak current limiter function and a RMS current limiter function. Limiter settings are retained separately for 100 V and 200 V ranges. Setting range limits can be set for output voltage and output frequency.

See “5.3.7 Set Peak current limiter settings”. See “5.3.8 Set RMS current limiter settings”.

Table3-12. Current Limiter Setting Ranges

For a capacitive load or inductive load, the peak current limiter may not achieve the peak current value as set, due to overshooting or undershooting the set current value, or variable output current waveforms while the limiter is operating. For an inductive load, operation of the limiter can cause the current to vary and, as a result, an output overvoltage may occur.

4.1 Use as a DC Power Source

When using the APS-1102A as a DC voltage source, select DC - Internal signal mode (AC+DC-INT), then enter the settings listed in Table4-1. AC components (sine wave, square wave, and arbitrary waveform) can be superimposed on the DC power source. A protection diode may be required to be connected, depending on the load, such as a capacitor or inductor.

Table4-1. Panel Settings When Using APS-1102A as a DC Power Source

The unit for AC voltage settings differs according to the AC voltage waveform setting.

4.1.1 Connecting output terminal to load during DC output

Use the output terminal on the rear panel when outputting DC+AC or only DC from the APS-1102A. If the load is a capacitor or inductive load, connect a diode for protection that meets the following specifications between the output terminal of the APS-1102A and the load.

 Maximum reverse voltage: 600 V or higher  Maximum forward current: 15 A or more (100 V range), 7.5 A or more (200 V range)

a) Capacitive load such as capacitor (about 50 F or more) and DC-DC converter

When a capacitive load is charged, the greater the voltage changes, the more the charge current becomes. Overshoot may be generated in the output currents depending on the load, even if the peak current limiter of the APS-1102A operates, thus turning off the output due to overcurrent protection. To avoid this, gradually lower the set voltage so that decrease of the voltage changes per certain unit time or use the sweep function of the sequence.

A block diode is required to prevent current from flowing from the load to the output terminal of the APS-1102A even if the output voltage is lowered. Connect the diode and the load serially as shown in Figure 4-1.

Once a diode has been connected, a load that does not consume power keeps its voltage charged. The voltage of the load may be slightly higher due to the overshoot voltage and should be carefully monitored.

b) Inductive load such as inductor

An inductive load generates a back EMF when current suddenly stops flowing, such as when the output is turned off. A backflow diode is required to absorb the back EMF. Connect a backflow diode in parallel with the load, as shown in Figure 4-2.

b) Calculation method of the measurement values

Output voltage and current are sampled and A/D converted at 50 kS/s in general or at 5 kS/s when a sequence program is running. The frequency bandwidth of each analog circuit from a voltage or current point to the A/D converter is 50 kHz. RMS, average and peak values of voltage or current and active power values are calculated with following formulas and sampled values over integer multiples of their periods nearest to 100 ms. The following values are used as the periods: frequency setting values in INT/ADD modes, synchronization frequency measurements in SYNC modes, and fixed values to 100 ms in EXT modes or when the frequency is lower than 10 Hz in any mode.

4.2 Measurement of Inrush Current

4.2.1 Inrush current

In such an electrical product as contains a capacitor input type rectifier circuit for the input power line, a current that is larger than the rated current may flow for a short time immediately after the power source switch is turned on. This current is called an “inrush current.” If the power source is not able to supply such a large current, enough power is not supplied to the product, and sometimes it does not start in the worst case. On the other hand, when such a large current passes through the power source line, the supply voltage is likely to decrease because of the voltage drop at the line impedance. There exists a standard to limit this effect within a certain level. Such a product should be driven by a power source with enough supply capacity

 Example of an inrush current An electric drill (rated 100 V AC/350 W) Upper: Voltage (100 V/div) Lower: Inrush current (10 A/div)

Even in a small electric drill, an inrush current of 14 Apk flows right after the power source is turned on. Since the rated current is 3.5 A, this represents a fourfold increase in the current flow.

The APS-1102A can supply four times as a large peaked current as the maximum current supporting such a usage. There is no need to use a power source with an extra large capacity in order to supply the inrush current (for a capacitor input circuit of CF = 4 or less). The initial phase of the output AC voltage is adjustable from 0.0 to 359.9 (in 0.1 steps), so the user can monitor how the current inrushes in the load under various phase conditions. The peak current hold measurement function enables the measurement of the maximum peak value for the current flowing at that time. The measurement value of the peak current is reference value.

When measuring the inrush current, set the peak current limiter to the maximum value. If the limiter setting is lowered, the inrush current measurement may be incorrect.

4.3 Measurement of Harmonic Current

Switching power sources are widely used in both consumer and industrial electrical products. The capacitor input type rectifier circuits that are used with such input power lines have disadvantages such as significant distortion of input current and a large amount of harmonic current. When a large amount of this current flows in the power source line, the equipment may experience operation faults, such as voltage distortion, which can cause the transformer to overheat, possibly resulting in a hazardous accident. The APS-1102A includes a function for measuring harmonic current. This measurement does not conform to the IEC or other standards.

This measurement can be performed only in AC-INT mode and when the fundamental wave (panel frequency setting) is either 50 Hz or 60 Hz. Absolute values of harmonic current in RMS and their percentages to the fundamental are displayed up to the 40th harmonics (2 kHz at 50 Hz fundamental). The measurement value of harmonic current is reference value.

When harmonic current measurement is selected, RMS value, average DC, and peak value measurements are not performed. If RMS value, average DC, or peak value has been set, harmonic current measurement is not performed.

4.4 Using the Sequence Function

4.4.1 Sequence operations

When the sequence function of the APS-1102A is used, the pattern to be output can be freely programmed. For example, if a series of voltage change patterns that will be used in voltage variation tests for car electronics are programmed in advance, the output will change according to the sequence, so the test can be completed in one series of operations.

In the sequence operation programming, DC, sine waves, and square waves, which are built in the APS-1102A, and arbitrary waveform (16 types) captured via the USB interface is able to use. Maximum step number is 255 (minimum step time is 0.1 ms). In each step, waveform, level, and duration time can be set and constant/keep/sweep can be chosen. In addition, sequences can be repeated from 1 to 999 times (or continuously). The APS-1102A is also equipped with other functions, such as for branching to a specified step during a sequence operation, and for starting, stopping, or holding a sequence operation. Data is saved to sequence memory automatically. These sequence functions can be used in AC-INT mode or AC+DC-INT mode.

Number of sequences: Retained for each operation mode (AC/AC+DC) and each output voltage

range (100 V/200 V). Number of steps: 1 to 255 (per sequence) Step time: 0.1 ms to 999.9999 s (resolution 0.1 ms or 0.0001 s) Operations within step: Constant, keep, or linear sweep Parameter: DC voltage

Sets step end phase as enabled or disabled.

[Step end]

The following parameters are provided to specify the action at the end of the step.

 Continue sequence (CONT)  Hold (HOLD)  Idle (STOP)

[Jump step]

The following parameters are provided to specify the destination step when a jump occurs after ending the current step.

 Jump to an arbitrary number step (1 to 255)  Jump to the next number step (0)

[Jump times]

The following parameters set a loop for jumping to the step specified by [jump step] the specified number of times. The following parameters are provided to specify the jump times.

 Specified number (1 to 999)  Infinite times (0)

[Branch step]

The following parameters are provided to specify the destination step for branch control.

 Change to arbitrary step number (1 to 255)  Continue step processing without changing (0)

The step transition parameters specify the next step and its timing.

Table4-5. Step Transition Parameters

When start is commanded during normal output while in idle mode, step 1 is executed, then the step jumps according to the specified sequence. If the [jump step] has not been specified (= 0), the step jumps according to the sequence of step numbers, but when the [jump step] has been specified (= 1 to 255), the step jumps to the step specified by that parameter. A step ends when the time specified by the [step time] has elapsed. If the [step end phase] has been specified as enabled, the step ends when the [step end phase] value becomes (0) after the [step time] has elapsed. If both [step end] and [jump step] have been specified, the [step end] specification takes priority.

<Start>

Sets Run mode. When changing from Idle mode, the operation goes to step 1 when <Start> is set, and the sequence is started. When changing from Hold mode, the sequence is resumed from where it was stopped when <Hold> was set. When <Hold> mode is set by the [step end] parameter, the sequence is resumed at the step specified by [jump step] when <Start> is set.

<Hold>

Changes from Run mode to Hold mode.

<Stop>

Changes to Idle mode. Immediately changes to normal output step. At that time, the values when <Stop> occurred are retained to the normal output step [output parameter]. If it is tried to set the output voltage at <Stop> to exceed the setting range limit, then the setting will change to 0 V. If it is tried to set the frequency out of the setting range limit, then the setting will change to the lower limit of the setting range. The output will turn off in these cases.

Changes to the step specified by [branch step]. Changes from the output at the time when <Branch> occurred to the [branch step].

e) Sequence loop

Either an entire sequence or a block of any number of steps within a sequence can be used as a sequence loop. The loop is implemented based on the [jump step] and [jump times] parameters specified for each step. The jump counter, which counts the number of jumps, functions within each step to retain a count, so multiple loops can be implemented.

Figure 4-9 below illustrates the loop specification method and the step transitions.

Figure 4-9. Loop Specification Method and Step Transition Example

---------- Notes -----------------------------------------------------------------------------------------------------

 [jump times] indicates the number of jumps. Consequently, loop times = jump times + 1.  In the example above, 10 jump times are specified for Step 6, so Step 5 and Step 6 are

executed 11 times.
