N69200 overview
The N69200 is a programmable dissipative DC electronic load for power testing from 2 to 60 kW. Five voltage classes up to 2,400 V and current variants up to 2,500 A cover low-voltage, high-current and high-voltage applications. Units up to 6 kW use a compact 3U, 19-inch chassis, while higher power levels are built as modular configurations. Three setting and measurement ranges plus precise voltage and current measurement provide a broad operating area. Static and combined load characteristics are complemented by dynamic transitions, frequency sweeps, user-defined current waveforms, protection-function tests, and charge and discharge procedures. Master-master and master-slave connections support project-specific power expansion. This makes the series suitable for research and development, validation systems, production and end-of-line testing, and automated test equipment.
Key benefits
High power density
Up to 6 kW is available in a 3U, 19-inch chassis, reducing rack space in the test system.
Multi-range architecture
Three ranges each for voltage, current, power and resistance combine fine resolution with a broad usable test area.
Short-term overload
Loading at up to 1.6 times rated power for less than three seconds supports transient power testing.
Precise voltage measurement
Measurement accuracy of 0.015% + 0.015% F.S. supports reliable analysis at 23 ± 5 °C.
Precise current measurement
Current is acquired with an accuracy of 0.04% + 0.04% F.S. at 23 ± 5 °C.
Adjustable control response
Adjustable CV loop speed helps match different power supplies and reduce control-loop oscillation.
DC electronic load operating principle
The N69200 draws electrical energy from the connected device under test and converts it into heat within its load modules. Depending on the selected operating mode, it regulates current, voltage, power or resistance to the programmed setpoint. Combined modes add limiting or transition behavior to the basic characteristics, enabling a closer reproduction of real loads.
Remote sense is available for precise voltage measurement at high currents or with long cables. Separate sense leads measure voltage directly at the DUT and compensate for voltage drop across the load cables. An optional NP101 module enables loading down to 0 V with selected 150 V models.
Loading down to 0 V: The NP101 module is an optional extension for selected 150 V configurations. Remote sense is mandatory for this operating condition.
Power range and operating characteristic
The product family combines five voltage classes with different power and current ratings. Maximum current draw is determined by the current limit, rated power and minimum operating voltage of the selected model. Full rated current is therefore not available at every low-voltage operating point.
| Voltage class | Available power | Maximum series current | Smallest form factor | Typical selection focus |
|---|---|---|---|---|
| 150 V | 2 to 60 kW | up to 2,500 A | 3U | Low-voltage and high-current tests, batteries, fuel cells and power supplies |
| 600 V | 2 to 60 kW | up to 2,500 A | 3U | DC links, charging electronics, industrial power supplies and energy systems |
| 1,200 V | 2 to 60 kW | up to 2,400 A | 3U | High-voltage components, power electronics and electric drive systems |
| 1,600 V | 3 to 60 kW | up to 720 A | 3U | High-voltage DC components, photovoltaic equipment and industrial power electronics |
| 2,400 V | 3 to 60 kW | up to 720 A | 3U | High-voltage testing of converters, energy components and DC systems |
Configurations range from 3U units to modular high-power systems. For example, 30 kW variants start at 15U and selected 60 kW variants start at 30U. The actual height depends on voltage class, current rating and module configuration.
Dynamic response and control behavior
Dynamic operation switches between two operating points and supports Continuous, Pulse and Toggle modes. Main value, transient value, pulse width, rise rate and fall rate can be programmed for dynamic current, voltage, resistance and power. The specified minimum rise time is 30 µs.
Fast load transitions
Dynamic operation up to 30 kHz tests control stability and transient response of power supplies.
Dynamic frequency sweep
Sampling at up to 500 kHz captures voltage peaks, voltage valleys and their corresponding frequency points.
Programmable current waveforms
Sine, square, triangle, ramp and user-defined waveforms reproduce repeatable current profiles.

Typical applications
Static, dynamic and automated procedures support validation of a wide range of DC sources, energy-storage devices and power-electronic components.
Automotive and e-mobility testing
On-board chargers, DC/DC converters and high-voltage components are loaded with static characteristics, transients and protection tests.
DC power supplies
CC, CP and dynamic profiles test regulation, stability, start-up behavior and protection thresholds.
Batteries and supercapacitors
Discharge profiles, capacity acquisition and optional DCIR/ESR measurement support energy-storage characterization.
Fuel cell systems
High current and programmable profiles reproduce stationary and dynamic power demands on stacks and systems.
PV and energy systems
MPPT characterizes PV modules, while CP and dynamic modes load DC components in energy and storage systems.
Production and end-of-line testing
Remote control, stored parameter sets and automatic sequences enable repeatable testing in production lines.
Interfaces, software and automation
| Interface or function | Status | Use |
|---|---|---|
| LAN | Standard | Ethernet remote control and integration into automated test systems |
| RS232 | Standard | Serial communication and connection of the optional GPIB converter |
| CAN | Standard | Communication through the control connector |
| SCPI, Modbus RTU, CANopen | Standard | Remote-control protocols for different automation environments |
| USB Host | Standard | Imports user-defined current waveforms from USB storage |
| External programming | Standard | 0 to 10 V analog current programming in CC mode |
| Current monitor output | Standard | 0 to 10 V analog signal proportional to the active current range |
| External trigger | Standard | TTL-compatible triggering for dynamic and external control procedures |
| PC software | Available | Configuration, remote operation, data display and historical data storage |
| GPIB | Optional | Connection through the separately available NE101 RS232-to-GPIB converter |
Up to 100 parameter sets for CC, CV, CR, CP and dynamic settings can be stored in non-volatile memory and recalled quickly. Multi-step sequences and automatic tests support repeatable procedures without continuous manual setpoint changes.
Parallel operation and power expansion
Units with the same voltage class can be connected in parallel for higher current and power. The N69200 supports both master-master and master-slave configurations. The current setpoint is entered at the master, and the connected units distribute the load within the configured total power.
Master-master operation
Multiple master units connect through the parallel ports and are controlled together by one leading instrument.
Master-slave operation
One master provides operation and setpoints while slave modules add load power.
Parallel units must have the same voltage specification. Cables, protective measures and busbars must be rated for the maximum total current of the configuration.
Installation and infrastructure
| Characteristic | Technical specification | Planning note |
|---|---|---|
| Supply | 220 V AC ±10%, 47 to 63 Hz | The control and auxiliary supply requires protective-earth connection. |
| Form factor | 19 inch, from 3U | Units up to 6 kW use 3U; higher power ratings use modular configurations. |
| 3U unit dimensions | 132.5 × 482.0 × 783.8 mm including handle and output cover | Rack depth, power cables and rear airflow must be considered during integration. |
| 3U unit weight | approximately 22 to 34 kg | Weight depends on power and voltage class. |
| Operating temperature | 0 to 40 °C | Air outlets must remain unobstructed. |
| Storage temperature | −20 to 60 °C | Store in dry, non-condensing conditions. |
| Environment | below 2,000 m, 5 to 90% RH, non-condensing | Applications outside these conditions require project-specific review. |
| Remote sense | Local or remote voltage acquisition | Four-wire sensing is appropriate for CV, CR and CP testing and where cable losses are significant. |
