Electronic DC Load

The DL series is a dc electronic load up to 300 W / 1 kW, realizing improved performance at low operating voltage and high speed response. It can be used as a test load for stabilized dc power supplies, fuel cells, photovoltaic cells, and so on. You can build up a 10 kW system at maximum with this series using optional system cables.

DL series
The DL series is a dc electronic load up to 300 W / 1 kW, realizing improved performance at low operating voltage and high speed response. It can be used as a test load for stabilized dc power supplies, fuel cells, photovoltaic cells, and so on. You can build up a 10 kW system at maximum with this series using optional system cables.

Low voltage operation like real resistors
*


The DL series is free from discontinuity in current at the minimum operating voltage, or slow rise owing to soft start function to avoid that, so operates like real resistors from 0 V.

*
Fast feedback control of current
*


Current overshoots or oscillations which tend to appear around set value are eliminated with fast feedback control of current. Smooth rising current waveform with high slew rate (30 A/μs max. at CC mode of DL1000L) is realized.

Available load modes are Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), Constant Power (CP), External Control (EXT) and Short (SHORT). Using current limit at CV mode operates like a CV/CC mode which is suitable for battery discharging. You can also switch modes or shut down load input automatically when the load voltage reaches set value, using a special function (VMode).

3 Sweep modes
*


Three types of characteristic tests can be executed using only a main unit: SweepR providing V-I characteristic tests, Sweep C providing overcurrent protection characteristic tests (with pass-fail judgements) of power source equipments and Sweep P providing overload protection characteristic function (with pass-fail judgements) of power source equipments.

Parallel operation, multi-channel synchronous operation
*


Parallel connection using optional system cables can provide up to a 10 kW system at maximum, and multi-channel synchronous operation can synchronize load on/off control, load fluctuation control, etc. of more than one DL series.

Ripple noise measurement (optional)
*


You can optionally add a measurement function which is equivalent to a ripple noise measurement with a 100 MHz oscilloscope recommended in the Japan Electronics and Information Technology Industries Association (JEITA) standard. Spike-like switching noises, influence of line-frequency, and so on are separated in this measurement. You can eliminate individual variations which often become a problem in measurements using oscilloscopes. Moreover, you can reduce the measurement time.
