DC Electronic Loads

DC electronic loads accurately simulate the loading of a circuit. Each unit implements sink waveforms which are programmable for voltage, current and power.

When compared to a traditional resistive load bank, a programmable electronic load offers much greater functionality. Sink values of selected models can be adjusted in small increments into the milliamp range, under a variety of waveforms. Whereas, a resistive load bank typically has much less control. Traditional systems do not have the programmability necessary to recreate the complex load steps of real world applications.

Due to variance in user behaviour, the operating waveforms of DC devices can often have many irregular qualities. For example, when testing a discharging xEV battery pack, a cautious driver will create a vastly different waveform than an aggressive driver that accelerates fast and brakes hard. Our DC loads allow the complex loading of an electrical circuit to be precisely simulated.

Common operating features throughout the rental range include OVP/OCP tests, front panel memory as well as CC, CV, CR and CP modes. Rise, fall and plateau times are adjustable in dynamic mode. Grid-tied power recycling loads are available with an embedded function generator, which can create almost any complex DC waveform.

Our rental systems are commonly used for discharging batteries, fuel cell loading, product burn-in trials and testing DC power supplies. Application specific GUIs are available for the LAB-GSS, which allow the DC load to accurately simulate battery pack and capacitor characteristics when testing chargers.

Did you know...

  • We also provide a selection of new DC electronic loads.
  • If you require both DC sink and source functionality, bidirectional DC systems are available to purchase.
  • A current waveform generator is available for most of our DC loads. This allows the electronic load to sink different levels of energy over time.
