N8330 battery simulator overview
The N8330 Series combines a programmable DC source for emulating individual cell voltages with high channel density and precise voltage control. The N8330A provides 24 channels rated at 0–6 V and 0–1 A each. The N8330B and N8330C each provide 16 channels rated at 0–5 V and 0–2 A or 0–3 A respectively. Every channel is isolated and can be set independently; multiple instruments can be connected in series for larger battery stacks. Four-wire sensing measures voltage directly at the DUT and reduces the influence of lead resistance. The 19-inch, 2U design is suited to test systems with many parallel stations. The associated application software supports multi-channel batch operation, graphical data display, analysis and reporting. LAN and isolated RS485 connect the battery simulator to automated test environments.
Key benefits
High channel density in 2U
Up to 24 channels in one 19-inch instrument reduce rack space and instrument count for parallel test tasks.
Precise cell voltages
10 µV resolution and 0.001% + 0.1 mV accuracy enable finely graduated setpoints and readback values.
Isolated channels
500 V DC inter-channel isolation facilitates multi-cell simulations and separate test stations.
Four-wire sensing at the DUT
Separate sense leads measure voltage at the connection point and compensate for voltage drop in the load leads.
Low ripple
Voltage ripple of no more than 2 mV RMS supports the emulation of a stable DC cell voltage.
Software-based multi-channel operation
Batch operation, graph display, data analysis and reporting simplify the evaluation of complex multi-channel tests.
Multi-channel battery simulation principle
Each output channel operates as an independently programmable DC source with constant-voltage and constant-current control. Voltage and the current limit are set and read back per channel. This provides defined cell voltages while limiting current within the range of the selected model.
Each channel is isolated from the other channels. Multiple N8330 instruments can be connected in series for larger battery stacks. The application software provides remote control and supports automated multi-channel testing.
Models and electrical ranges
| Model | Channels | Voltage per channel | Current per channel | Power per channel |
|---|---|---|---|---|
| N8330A | 24 | 0–6 V | 0–1 A | 6 W |
| N8330B | 16 | 0–5 V | 0–2 A | 10 W |
| N8330C | 16 | 0–5 V | 0–3 A | 15 W |
Selection note: Channel count, maximum cell voltage, current limit and power apply per channel. Every operating point must remain within the model's voltage, current and power ratings at the same time.
Accuracy and dynamic behaviour
| Parameter | Specification | Condition |
|---|---|---|
| Voltage setting accuracy | 0.001% + 0.1 mV | 23 ± 5 °C |
| Voltage readback accuracy | 0.001% + 0.1 mV | 23 ± 5 °C |
| Setting and readback resolution | 0.01 mV | All models |
| Voltage ripple | ≤ 2 mV RMS | 20 Hz–20 MHz |
| Voltage rise time | ≤ 5 ms | No load and full load, 10–90% of final value |
| Voltage fall time at full load | N8330A: ≤ 30 ms; N8330B: ≤ 20 ms; N8330C: ≤ 10 ms | 90–10% of final value |
| Transient recovery time | ≤ 200 µs | 10 to 90% load change at full output voltage; recovery to within ± 50 mV |
| Communication response time | ≤ 10 ms | Instrument interface |
Four-wire sensing separates the current path from voltage measurement. This measures voltage at the DUT and largely removes the voltage drop across the connecting leads from the control result.
