ASR-2000 Series User Manual Theory of Operation The theory of operation chapter describes the basic principles of operation, protection modes and important considerations that must be taken into account before use. Description of ASR-2000 System System block are composed of the parts described below.  Input EMI Filter A two stage π filter and a passive PFC circuit that and PFC Circuit convert AC power to DC power.
PAGE 25
GETTING STARTED Glossary Rate Output Maximum Power Capacity The maximum value of the output power capacity will be provided consecutively when the following situations exist: Output voltage is 100 to 175 V within the 100 V range. Output voltage is 200 to 350 V within the 200 V range. Output frequency is 40 to 999.9 Hz in AC mode. Output frequency is 1 to 999.9 Hz in AC+DC mode. Output voltage is 100 to 250 V within the 100 V range in DC mode.
PAGE 26
ASR-2000 Series User Manual Equation: Maximum Peak Current (AC-INT mode only) The maximum value of the output current (peak value) will be provided consecutively to a capacitor input-type rectifying load when the following situations exist: Output voltage is 100 to 175 V within the 100 V range. Output voltage is 200 to 350 V within the 200 V range. Output frequency is 40 to 999.9 Hz in AC mode, and 1 to 999.9 Hz in AC+DC mode.
PAGE 27
GETTING STARTED Crest Factor (CF) The crest factor stands for a ratio of the rms value correlated to the peak value (crest value) of the waveform. Equation: Note Inrush Current Capacity Output Power Ratio The crest factor is 1.41 of sine wave. It indicates the current, which is able to be supplied to a load, exceeds the rating for a short period and the duration. It indicates the output power of a percentage where the rated maximum output power is 100%.

ASR-2000 Series User Manual Abnormal Internal This alarm is activated and output will be disabled Control immediately when internal control abnormality is detected. Beware that all operations will be disabled except for the power shutdown operation if an error occurs. V-Limit Voltage limit protection prevents a high voltage from damaging the DUT. This alarm can be set by the user. F-Limit Frequency limit protection prevents a high frequency from damaging the DUT. This alarm can be set by the user.
PAGE 29
GETTING STARTED Considerations The following situations should be taken into consideration when using the power supply. Inrush Current When the power supply switch is first turned on, an inrush current is generated. Ensure there is enough power available for the power supply when first turned on, especially if a number of units are turned on at the same time. Capacitive Load When the power supply connects to a capacitive load, e.g.
PAGE 30
ASR-2000 Series User Manual Inductive Load When the power supply connects to an inductive load, e.g., inductor, which generates a back EMF (Electromotive Force) when output current is accidentally turned off, a backflow diode is necessary for absorbing the back EMF, which may cause irreversible damage to the power supply. Refer to the following figure where a backflow diode connects with the inductive load in parallel to effectively absorb the possible back EMF.
PAGE 31
GETTING STARTED Grounding The output terminals of the ASR-2000 series are isolated with respect to the protective grounding terminal. The insulation capacity of the load, the load cables and other connected devices must be taken into consideration when connected to the protective ground or when floating.

PAGE 53
OPERATION Wire Gauge Considerations Background Before connecting the output terminals to a load, the wire gauge of the cables should be considered. It is essential that the current capacity of the load cables is adequate. The rating of the cables must equal or exceed the maximum current rated output of the instrument. Recommended Wire Gauge Wire Gauge Nominal Cross Maximum Current Section 20 0.5 9 18 0.75 11 18 1 13 16 1.5 18 14 2.
PAGE 54
ASR-2000 Series User Manual To minimize noise pickup or radiation, the load wires and remote sense wires should be twistedpairs of the shortest possible length. Shielding of the sense leads may be necessary in high noise environments. Where shielding is used, connect the shield to the chassis via the rear panel ground screw. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to reduce coupling, which might impact the stability of the power supply.

TEST MODE FUNCTION Trans1 This step configures the transition from normal to abnormal conditions. This step will linearly interpolate the normal settings to the abnormal settings. This step can be skipped for abrupt state changes. Abnormal This step contains the abnormal conditions for the simulation. Trans2 This step configures the transition from abnormal to normal conditions. Normal2 This step configures the normal conditions that supersede the abnormal conditions.
