N6200 overview: programmable DC electronic load
The N6200 series loads DC sources using defined electrical setpoints. Ten models provide rated powers of 600 W, 1,200 W or 1,800 W. Voltage variants extend to 60 V, 150 V or 600 V, with maximum currents from 10 A to 150 A depending on the model. Voltage, current and power limits must all be observed at the operating point.
The instruments combine four basic operating modes with dynamic load changes, sequences, automatic limit checks and dedicated battery and power supply tests. CC, CV and CR offer dual ranges. A display, function keys, numeric keypad and rotary knob provide local operation, while communication interfaces and analogue signals support test bench integration. The 2U chassis suits benchtop use and 19-inch racks. Remote sense measures voltage directly at the DUT, reducing the influence of load leads on voltage measurement.
Key benefits
Hardware-based control
CR and CP regulation use hardware circuits. This supports fast responses to voltage changes without continuous software-based setpoint calculation.
Match the loop response
Three CV response settings allow adaptation to the connected source and help avoid oscillations in the test setup.
Sequences with result evaluation
Sequence steps combine load mode, setpoint, slew rates and dwell time. Auto Test checks voltage, current or power limits and displays PASS/FAIL.
Measure voltage at the DUT
Four-wire sensing through S+ and S− reduces the influence of lead voltage drops, particularly in CV, CR and CP tests.
Analogue control and monitoring
External CC programming and current monitoring use 0–10 V signals referenced to the active current range, supporting test bench integration.
Investigate internal resistance
The optional ESR/DCIR function calculates DC internal resistance from current changes and the voltage response of batteries or supercapacitors.
Operating principle and modes
| Function | Operation | Benefit |
|---|---|---|
| CC – Constant current | Maintains the current drawn at the programmed value. | Defined current loading and discharge. |
| CV – Constant voltage | Adjusts the current drawn to maintain the input voltage at the setpoint. | Voltage-controlled loading of a source. |
| CR – Constant resistance | Load current follows input voltage according to I = U/R. | Emulation of a resistive load. |
| CP – Constant power | Load current follows I = P/U within the instrument limits. | Constant power consumption as voltage changes. |
Operating range and model overview
| Model | Max. voltage | Max. current | Rated power | Min. operating voltage at stated current |
|---|---|---|---|---|
| N6206-60-10 | 60 V | 10 A | 600 W | 2 V / 10 A |
| N6206-60-50 | 60 V | 50 A | 600 W | 2 V / 50 A |
| N6206-150-50 | 150 V | 50 A | 600 W | 2 V / 50 A |
| N6206-600-10 | 600 V | 10 A | 600 W | 4.5 V / 10 A |
| N6212-60-100 | 60 V | 100 A | 1,200 W | 2 V / 100 A |
| N6212-150-100 | 150 V | 100 A | 1,200 W | 2 V / 100 A |
| N6212-600-20 | 600 V | 20 A | 1,200 W | 4.5 V / 20 A |
| N6218-60-150 | 60 V | 150 A | 1,800 W | 2 V / 150 A |
| N6218-150-150 | 150 V | 150 A | 1,800 W | 2 V / 150 A |
| N6218-600-30 | 600 V | 30 A | 1,800 W | 4.5 V / 30 A |
For U > 0 within the permitted operating envelope: I ≤ min(I-rated, P-rated/U). Maximum voltage and minimum operating voltage must also be observed. For example, the N6218-150-150 can draw no more than 12 A at 150 V because its rated power is 1,800 W. The 150 V and 150 A ratings are not available simultaneously.
Dynamic operation and control response
TRAN operation generates load changes in current, voltage, resistance or power. Conti alternates continuously between two levels; Pulse generates one load pulse after a trigger; Toggle switches to the other level on each trigger. Rising and falling slew rates are adjustable. The actual response also depends on the source and connecting leads. CV control offers slow, medium and fast response settings.
Programmable tests and dedicated functions
| Function | Operation | Benefit |
|---|---|---|
| SEQ / Auto Test | Up to 100 files with up to 50 steps each; load mode, setpoint, slew rates, dwell time and limits per step. | Repeatable test sequences with PASS/FAIL evaluation. |
| Discharge test | Constant current loading until the programmed end voltage is reached. | Controlled discharge of batteries and supercapacitors. |
| Charge test | External power supply, load and storage device connected in series; remote sense at the storage device. CC charging with a transition to CV is supported. | Controlled charging tests using an additional external energy source. |
| OCP test | Increases load current in steps and compares input voltage against an end-voltage threshold. | Investigation of source overcurrent protection. |
| ESR / DCIR – optional | Measures the voltage change during a defined current load. | Determination of DC internal resistance. |
| MPPT | CV-based investigation of a solar module; results include MPP, Vmp, Imp, Voc and Isc. | Determination of the maximum power point within the load limits. |
| Short-circuit simulation | Selectable short-circuit test function. | Investigation of source response under the corresponding test load. |
Typical applications
Medium-power supplies
Static operating points, dynamic load changes and OCP tests investigate the output behaviour of the power supply.
Battery packs
The load discharges battery packs at a defined current down to the end voltage. Optional DCIR testing adds internal resistance measurement.
Supercapacitors
The discharge function and optional ESR/DCIR measurement support investigation of discharge behaviour and DC internal resistance.
Automated electrical test sequences
Auto Test executes stored load steps and evaluates voltage, current or power against defined limits.

Protection functions and stop conditions
Programmable OCP, OVP and OPP thresholds switch the load off in the event of overcurrent, overvoltage or overpower. Temperature monitoring and module overheat protection also stop loading. Additional functions include a current limit, timed unloading and Von/Voff. Von applies in CC mode and must be set above Voff. Behaviour when the voltage threshold is reached again depends on the selected latch mode.
Frequently asked questions about N6200
How do I select the appropriate model?
Check maximum voltage, required current and power at the actual operating point together. At low test voltages, also account for the minimum operating voltage.
Can maximum voltage and maximum current be used simultaneously?
Only if their product remains within rated power. For example, the N6218-150-150 is power-limited to 12 A at 150 V.
Can current be programmed through an analogue signal?
Yes. When enabled, the 0–10 V programming input controls zero to full scale of the selected current range in CC mode. The input voltage must not exceed 10 V.
When should remote sense be used?
When load leads cause relevant voltage drops, particularly in CV, CR and CP operation. Connect S+ and S− directly to the DUT output.
Is ESR/DCIR measurement included as standard?
This function is optional. It determines DC internal resistance from the voltage response to a current change.
Can N6200 discharge battery packs?
Yes. The discharge function draws a defined current and stops at the programmed end voltage. Voltage, current and power limits must still be observed.
Can N6200 charge and discharge supercapacitors?
Discharging is directly available as a load function. Charge testing requires an additional external power supply, a series connection and remote sense at the supercapacitor.
Can it test power supply overcurrent protection?
Yes. The OCP test increases load current in steps and detects operation using the selected end-voltage threshold. Test current and power must remain within instrument limits.
