3. Operation

1.Voltage Setting:

Voltage setting contents ‘110V ’, “ 220V ’, ‘▲’ and ‘▼’ four keys .

a. When any one of the keys mentioned above is pressed, the voltage

display will flash one time, the APS9301/9501/9102 will go to the setting mode and show the voltage setting value.

b. If the ‘110V’ Key is pressed, the output voltage will be adjusted to

110V immediately. Meanwhile, the voltage display will switch back to the reading mode automatically.

c. If the ‘220V’ key is pressed for 0.2 seconds continuously ( for safety

reason, must be), the output voltage will be adjusted to 220V. Meanwhile, the voltage display will switch back to the reading mode automatically.

Note: It would not work if the output voltage is setting on low range.

(0～150V output)

d. If either “▲” or “▼”key is pressed for 0.5 seconds continuously, the

output voltage will be adjusted. If either “▲” or “▼” is pressed twice continuously, the output voltage will be adjusted immediately.

e. The adjusting rates are 0.1V/step on fine adjust mode and 1V/step on

coarse adjust mode.

f. The first six steps of adjustment will be spent 0.25 seconds per step. If

the key “▲” or “▼” is pressed continuously, it will spend 0.13 second per step for the rest steps. If the key is released, the voltage adjustment would be stopped and go back to the original adjustment speed (0.25 seconds per step) automatically.

g. If the output mode is setting ON ( the indicator ‘OUTPUT’ would light),

the output voltage could follow the setting voltage simultaneously

Caution: When you adjust the voltage at “▲” or “▼” mode, it is

better to switch off the output to avoid unnecessary damage because of accidental voltage adjustment.

h. If any key mentioned above is not pressed for 2 seconds continuously,

APS-9301/9501/9102 would go back to the normal operation and

the voltage display could show the reading value automatically.

2.Frequency Setting:

changed immediately to 50Hz, 60Hz respectively. Meanwhile the output frequency will be changed coincidentally.

b. The frequency ranges from 45Hz to 99.9Hz can be adjusted by 0.1 Hz

per step in fine adjustment mode and 1 Hz per step in coarse adjustment mode. The frequency ranges from 100Hz to 500Hz can be adjusted by 1 Hz per step in fine adjustment and 10Hz per second in coarse adjustment mode.

c. The other setting are same as voltage setting.

3.High / Low Voltage range selection:

Press the key of ‘RANGE’, if the indicator lights, the output voltage would be setting on the high voltage range, otherwise, the system would be setting on low voltage range. The changed range would not cause the setting voltage to change, however, there is a 20ms interruption during the voltage range changing. The non-reasonable range changing (For example, the voltage sets 200V but the range is changed to the low range) is not acceptable by APS-9301/9501/9102.

Note: High range voltage 0 ~ 300V

Low range voltage 0 ~ 150V

4.Instrumentation selection:

6. Circuit Principle

The APS series products are controlled by CPU and operated via keyboard. The APS series are fully digital controlled.

The input isolate transformer has bee applied to isolate the city power from the APS series. And step down the input voltage for appropriate applications. The main AC power is rectified and filtered to become a very smooth DC source for power amplifier. Sine ware form is generated by the digital synthesizer and filtered by a very high impedance filter. Therefore, the sine ware form will be very stable and the distortion will be reduced.

The APS series have two voltage feedback systems. One is analog feedback system for quick response(within 100us), and the regulation will be located In the range of ±5%. The other is digital feedback system. The system will read the output voltage and compare with the settings. The accuracy of Output voltage will be limited in the range of ±0.1V.

The sine wave signal is amplified by power amplifier. The power amplifier provides a very clean and low distortion sine ware to the output of APS series through the output transformer. The offset and calibration data of instrumentation are stored in the EEPROM. The instrumentation would be Calibrated automatically when the APS series is switched on. True RMS circuit is applied for the voltmeter and ammeter. The value of LED display is true RMS value.

For easy operation, the APS series equips a memory of EEPROM. The EEPROM will memorize the latest settings data automatically after the APS Series have been switched off. If the APS series is switched on again, the CPU could read all the data from the EEPROM and provide the output value same as the previous setting. It is unnecessary to reset the data after APS series are switched off.
