1.1 General 1.1 General The APS-1102 programmable AC/DC power source is a power source that can output AC and DC power, features a compact design for convenient desktop use, and provides a wealth of measurement functions. Rated output voltage is 100 Vrms (100 V range) or 200 Vrms (200 V range), with maximum output capacity of 1 kVA (during AC 200 V input). It also features eight output modes, with DC output, external input amplification, and line-synchronized output.
PAGE 17
1.3 Applications  Enables AC-superimposed DC output When in the AC+DC mode, an AC wave (sine wave, square wave, or arbitrary waveform) can be superimposed on the DC output.  Also supports capacitor input load (up to crest factor 4 is supported) Enables peak current output of up to four times as large as the rated current (RMS value).  Can be used as an external input amplifier When “internal + external” is selected, an internal signal source can be added to the external signal input.

3.3 I/O Terminals 3.3 I/O Terminals 3.3.1 Output terminals (front and rear)  Connection to output outlet (front) The front panel is equipped with universal type output outlets that accommodate power plug types from various countries. These outputs are isolated from the power inputs and case (ground connection). These outlets are used only for AC power. Use the rear output terminal for DC or AC+DC. Polarity follows the Japanese standard.
PAGE 38
3.3 I/O Terminals  Connection to output terminals (rear) Outputs are isolated from the input power lines and the case (ground connection). When connecting to an output terminal, attach a round crimp contact with a sleeve that has sufficient capacity for the output current. DC output is based on “Lo”, so that the + polarity setting sets “Hi = positive”, and the - polarity setting sets “Hi = negative”. Output terminal Figure 3-5.
PAGE 39
3.3 I/O Terminals  Connect cables to the output terminal block as described below. Outputs are isolated from the input power lines and case. 1. Remove a screw attached to the output terminal block. 2. Insert the screw through the round crimp contact at the end of the cable. 3. Reattach the screw into the OUTPUT terminal while holding the crimp contact in place. 4. Turn the screw until it is securely fastened. The recommended fastening torque is 1.2 (Nm). 5.

4.4 Using the Sequence Function 4.4 Using the Sequence Function 4.4.1 Sequence operations When the sequence function of the APS-1102 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.
PAGE 86
4.4 Using the Sequence Function a) Sequence A sequence is comprised of a combination of at least two steps (the minimum unit is one step). b) Step Step execution parameters and step transition parameters are specified for each step. When sequence execution is not performed (i.e., during normal output mode), these parameters are specified in the same way. Thereafter, the normal output mode is called normal output step. In the descriptions below, the step parameters are enclosed in brackets ([]).
PAGE 87
4.4 Using the Sequence Function The step transition parameters specify the next step and its timing. Table 4-5. Step Transition Parameters [Step time] [Step end phase] [Step end] [Jump step] [Jump times] [Branch step] Specified in time Sets step end phase as enabled or disabled. The following parameters are provided to specify the action at the end of the step.

When changing from Hold mode, the sequence is resumed from where it was stopped when was set.

4.4 Using the Sequence Function 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.

6.7 Programming Precautions 6.7 Programming Precautions a) Arbitrary waveform data Arbitrary waveform data comprises a block of binary data. The preceding ASCII program message command field and the binary data block arbitrary waveform data should be transferred at the same time. Always transfer arbitrary waveform data in 4096-word (8192-byte) batches. If the data count is insufficient, an error may occur, in which case the correct waveforms cannot be output.

8.2 Routine Maintenance b) When fan filter is dirty Two air filters are provided to filter out dust that gathers through the air inlets in the front panel. When too much dirt accumulates in the filters, it can clog them and reduce air flow, causing higher internal temperatures which can reduce reliability. Periodically check the condition of the air filters. The air filters should be cleaned about once a month, or whenever fine dust has accumulated in the filter.
