Phase/AMP Series DPA1/DCPA1
3-24.
It is the customer's responsibility to determine the proper setting of the CURRENT LIMIT control on the
Current Limit device for his particular load. Once the proper setting of the control has been found, there should
be no need to make further adjustments unless load characteristics vary with continued use.
3-25.
OPTIONAL CURRENT INDICATOR.
3-26.
The optional Current Indicator (ammeter) may or may not be part of the optional Current Limit device.
The meter is calibrated to indicate the output current of the PHASE/AMP from zero to maximum on a scale
marked from 0 to 5. Thus, my multiplying the Current Indicator reading by 20 percent, the percentage of actual
maximum rated output current delivered to the load can be calculated. Output current in amperes can be
calculated by multiplying the Current Indicator reading by the scale factor which is obtained by dividing the
rated current output of the PHASE/AMP by five. For example, if the PHASE/AMP to be used is rated at 15
amperes, a Current Indicator reading of two units corresponds to a 6 ampere load current.
3-27.
OPTIONAL VOLTAGE INDICATOR.
3-28.
The optional Voltage Indicator provides a direct indication of the RMS output Voltage across the load.
Indicators are available to match the rated input Voltage of all DPA-1 models.
