NOTE
DRK series are not applicable to such application that electric power is infused externally or regeneration behavior is made.
Therefore they are not suitable for such devises that "returning generated electric power to AC line" or "being connected directly to the grid-connected power system". Please make AC output in combination with our high speed four-quadrant bipolar power supplies and such devices.
Functions
New Function Software calculated Remote sensing (at -LSn option)
It is possible to calculate differences between set value of output voltage and the voltage drop in the load end by resistance of output line and compensate for it. (Automatic Gain Control)
New Function Cut-off function to protect the load and Limiting function to withstand inrush current
There are various kinds of electrical devices that operate with AC voltage, and they may be required to stop immediately when abnormal current flows, or to continue to operate with some overcurrent. DRK series can set such behavior as necessary.
Cut-off function
It stops AC output safely when abnormal current flows into the load.
Limiting function
DRK adjusts the output current within the rated range and keeps supplying AC output when the load such as a motor at which the current several times as large as the rated current flows during startup is connected.
Refined and Simplified Operability
As it is able to call up commonly-used functions or output settings immediately, work efficiency is increased. For the application utilized in the same settings, as the latest settings are memorized, it is able to eliminate troublesome re-settings.
In case that several test patterns are repeated (for example, 90 V to 100 V to 110 V, 50 Hz/60 Hz), testing time is shortened very much by using the memory function.
Light, Compact and Space-saving
They have been considerably compact in comparison with traditional AC power sources and power sources which satisfy the needs of factories and experiment rooms requiring space-saving.
Standard functions and Plenty of Options
External control is quipped as standard. They are applicable automation of production lines immediately as it is able to control remotely output ON/OFF, voltage, frequency and ranges. And LAN, RS-232C, RS-485 and GPIB are applicable by option.

Various output: 3-phase output, Single phase 3-wire output, Master/Slave
3-phase output, single phase 3-wire output and master/slave hooking are applicable by options.
Also, they are applicable as a simple power supply by cancelation of option settings.
3-phase output
It is possible to test and evaluate 3-phase AC even where only single phase 200 Vac or 100 Vac is available
(3-phase output is planned with 1.2 kVA or 2 kVA model.)
