1.3 Features
  Switchable phase configuration
The output phase configuration (single-phase two-wire / single-phase three-wire / three-phase
four-wire) can be switched in one cabinet.

  Various interfaces to address a variety of usage
The interface to use for the remote controlling from a computer or sequencer is equipped. USB and
RS232 interface are standard, and either GPIB or LAN (LXI 1.4) interface can be chosen when
ordering. You can use a contact/TTL signal to turn the output on/off or switch the memory without
using a computer. The product also offers the status output for showing the device status and the
output which is synchronized with Sequence or Simulation step. With these functions you can
achieve various types of systemization and automatization. The AGC function and Autocal function
for calibrating the output voltage drop are also provided.
  Sequence function
User can program a sequence to change output voltage, frequency, waveforms and so on with this
function, which provides automation of switching continuously a number of testing conditions.
 
Power fluctuation test (=Simulation) function
User can simulate power line abnormalities, such as blackout, voltage rise, voltage drop, abrupt phase
change, abrupt frequency change, and so on.


 Variable current limiter
This function can limit the effective value and the positive/negative peak value of the output current
where the limiting value is variable. You can set the limiter so that the output is turned off when the
limited condition continues for a certain time.


 Short reverse power flow
This product support reverse power flow for 20 ms. User does not need to consult with the power
companies about power system interconnection because this product processes the reverse power
internally and does not regenerate to the power system when the reverse power flow is occurring.
  Power input
For DP060LM and DP120LM, either single-phase input or three-phase three-wire input or
three-phase four-wire input can be chosen when ordering. For DP180LM, either three-phase
three-wire input or three-phase four-wire input can be chosen.
  Feature-rich measurement function
On the panel the product displays the effective value, peak value, average DC value, current
peak-hold value, and active/apparent power of the output voltage/current. Furthermore, the power
factor, crest factor, reactive power, and harmonic current are also measured and displayed.
