Bidirectional Current Flow
Each channel can source or sink current, supporting charge and discharge tests without an additional electronic load.
N8352 – Programmable Dual-Channel Battery Simulator up to ±5 A per Channel
For reproducible testing of portable battery-powered devices and protection circuits.
Multiple current measurement ranges and a dedicated microamp range capture active operating conditions as well as very low standby currents. Two integrated voltage measurement channels complement the programmable outputs and allow additional supply points on the device under test to be observed directly.
Programmable Battery Models
Initial voltage, internal resistance, capacity and further parameters can be configured independently for both channels.
Integrated Fault Simulation
Short circuit, reverse polarity and open positive or negative terminals can be reproduced under controlled conditions.
LAN and RS232 Integration
Two LAN ports and an RS232 interface support integration into automated test and production systems.

N8352 series overview
The N8352 series combines two independently programmable output channels with bidirectional current flow and precise measurement capabilities. Six models cover output ranges of 0 to 6 V, 0 to 15 V or 0 to 20 V and channel currents from ±1 A to ±5 A. Rated power ranges from 6 W to 75 W per channel.
The programmable battery simulator can operate as a voltage source, current sink and reproducible battery model. Adjustable internal resistance, charge and discharge functions, SOC and sequence tests and defined fault conditions support testing of portable electronics, protection circuits and battery-powered tools. The compact 2U enclosure includes a 4.3-inch touchscreen, two additional DVM inputs and LAN and RS232 interfaces.
Key benefits
Precise Standby Current Measurement
The finest range measures currents from −1 mA to +1 mA with 0.1 µA resolution and 1 µA accuracy.
Fast Voltage Rise
Rise times below 40 µs support dynamic load changes and short supply scenarios without unwanted voltage overshoot.
Additional Voltage Measurement
Two DVM channels measure external voltages from −30 V to +30 V with 0.1 mV resolution.
Multiple Current Ranges
Three measurement ranges combine the rated channel current with improved resolution for low operating and standby currents.
Compact Benchtop Format
The 88 × 214 × 388 mm enclosure requires limited bench space and has an approximate net weight of 3.3 kg.
Independent Channels
Voltage, current limits and battery parameters are configured separately for both channels and read back in real time.
Battery simulator operating principle
Each output operates in two quadrants. Current can flow in either direction, allowing a channel to supply the device under test or absorb current from it. Charging and discharging behaviour can therefore be evaluated without changing the test wiring.
Source mode provides programmable output voltage and current limiting. Battery emulation supports parameters including initial voltage, internal resistance and capacity. The programmable internal resistance range of 0 to 20 Ω reproduces the voltage drop behaviour of a real battery.
Practical benefit:
When testing charge and discharge protection circuits, one channel can provide the external supply while the other emulates the battery terminal. No rewiring between charge and discharge tests is required.

Dynamic performance and regulation
Fast voltage transitions support short supply variations and dynamic operating conditions. The specified rise and fall times apply under both no-load conditions and purely resistive full load.
| Dynamic parameter | N8352A to N8352C | N8352D to N8352F |
|---|---|---|
| Voltage rise time, 10% to 90% of final value | <40 µs | <40 µs |
| Voltage fall time, 90% to 10% of final value | <100 µs | <100 µs |
| Transient voltage drop | 200 mV | 400 mV |
| Transient recovery time | <100 µs | <200 µs |
| Communication response time | ≤10 ms | ≤10 ms |
Voltage transitions are performed without overshoot under no-load and loaded conditions. This helps prevent temporary overvoltage or undervoltage stress when the simulated battery voltage is increased or reduced.
