(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees and their requirements as follows. The ASR-2000 falls under degree

Pollution refers to “addition of foreign matter, solid, liquid, or

gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.

 Pollution degree 1: No pollution or only dry, non-conductive

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Remote Sense Error

Sense alarm. This alarm will detect if the sense wires have been connected to the wrong polarity.

AC Fail

AC failure. This alarm function is activated when a low AC input is detected.

FAN Fail

Fan failure. This alarm function is activated when the fan RPMs drop to an abnormally low level.

GETTING STARTED

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., capacitor, the load is being charged consecutively and the larger the voltage change, the more the current grow. Also, the overshoot will be possibly generated within the currents output, therefore leading to output turned off thanks to overcurrent protection from the power supply.

It is suggested to lower down the set voltage output from power supply so that the voltage of capacitive load decreases per certain unit time. In addition, a block diode is necessary to keep current from flowing back to the output terminal of power supply. Refer to the figure below where a block diode connects with the capacitive load in series to efficiently prevent current from flowing back to the power supply.

Capacitive Load

Block Diode

ASR-2000

Considerations

The following situations should be taken into consideration when using the power supply.

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.

Inductive Load

Backflow Diode

ASR-2000

CAUTION

Ensure the connected diode meets the following specifications between the load, either capacitor or inductor, and the ASR-2000 series power supplies.

 Maximum reverse voltage: 600 V or higher  Maximum forward current: 15 A or more for

100V range, and 7.5 A or more for 200V range

GETTING STARTED

Grounded Neutral Output

Basically, grounded return on the neutral output is allowed for ASR-2000 series and electric shock may occur if not following the grounding procedure based on the local electrical safety codes. In some cases, 0 V is specifically required between ground and neutral, which can substantially moderate ground loops, thus keeping sensitive equipment from effects of ground loops and reducing ground noise.

Ground & Neutral Shortcut Illustration

LINE NEUTRAL GROUND

CAUTION

Owning to the fact that the neutral has been shortcut with the ground which is referenced to the chassis ground, few electric shocks may still take place from time to time, for which we sincerely ask your additional attention.

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.

The maximum temperature rise can only be 60 degrees above the ambient temperature. The ambient temperature must be less than 30 degrees.

Wire Gauge Considerations

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 twistedpairs to reduce coupling, which might impact the stability of the power supply. The sense leads should be separated from the power leads.

Menu Tree

Convention

Use the menu trees as a handy reference for the power supply functions and properties. The ASR-2050 / ASR2050R / ASR-2100 / ASR-2100R menu system is arranged in a hierarchical tree. Each hierarchical level, which is coated in varied colors, can be navigated through the orders within the diagrams below.

IRMS & I Limit On/Off

Almost identical with the concept of previous IPK Limit function, the IRMS/I Limit function keeps the IRMS/I value within the certain limit when the predefined value is reached. However, due to RMS calculation, the unit requires approximate 200ms of detect time before starting the adjustment process so that the IRMS/I limit can be well maintained. If, on the other hand, this function is turned off, the output will be disabled instantly when IRMS/I Limit off level is reached.

WARNING

Both of these outputs are electrically linked. Only one DUT should be connected to any one of the outputs at a time. Using both outputs at the same time is not supported. Using the front and rear outputs at the same time could cause dangerous operating conditions. See page 38 for details about using the output terminals or sockets.

Turn Output On

Press the Output key. The Output key will light up in orange and ON will be displayed in the status bar to indicate that the output is on.

Turn Output Off

Press the Output key. The Output key light will go out and OFF will be displayed in the status bar to indicate that the output is off.

Turning the Output On/Off

When the output is turned on, the DUT can be connected to either the rear panel output or the front panel output.

OPERATION

WARNING

Ensure the output is off before handling the remote sense connectors.

Use sense cables with a voltage rating exceeding the isolation voltage of the power supply.

Never connect sensing cables when the output is on. Electric shock or damage to the power supply could result.

Remote Sensing Input Connectors Overview

The remote sensing input connector is located at the rear panel of the ASR-2000.

Local Sense Operation

When using local sense, the remote sensing input terminal is not used. No compensation of any possible voltage drop seen on the load cables is performed. Local sense is only recommended when the voltage drop is of no consequence. By default, the power supply is configured for local sense.

1. Check that the remote sense setting is disabled

(page 121).

Advanced Settings

 Using the Remote Sense Function → from page 97  Preset Settings → from page 100

Using the Remote Sense Function

The ASR-2000 can be operated using local or remote voltage sense. By default, the power supply is configured for local sense.

Local Sense

Remote Sense

Remote Sense Operation

Remote sense is used to compensate for the voltage drop seen across load cables due to resistance inherent in the load cables. The remote sense function can compensate a maximum of 5% of the output voltage and all of output frequency.

1. Configure the remote sense setting to ON

(page 121).

2. Connect the Neutral terminal of the remote

sense terminal block to the Neutral terminal of the load.

3. Connect the Live terminal of the remote sense

terminal block to the Live terminal of the load.
