N8352 Main Functions
Power Mode
As a dual-channel power supply, users can set output voltage and output current limit value on N8352. N8352 provides multiple current ranges which can improve the output and measurement accuracy.

Battery Simulation
N8352 dual channels provide independent setting of initial voltage, internal resistance, battery capacity and other related parameters, and readback in real time. It can be used to solve the difficulty of parameter uncontrollability for real battery in test and to improve test efficiency.

Fault Simulation
N8352 provides the following fault states: positive & negative polarity open circuit, reverse polarity connection and short circuit.

Current flowing in both directions to make N8352 both a power supply and a load
The current flows in both directions. N8352 can both suck and output current. The output terminal has a switch module, which can physically disconnect from the external circuit in the closed state.


Variable output impedance allowing battery internal resistance simulation
N8352 has the battery internal resistance simulation function, and supports resistance value programming. The programmable range is 0-1Ω, which can emulate the variation graph consistent with the real battery internal resistance characteristics.


Ultra-fast transient response without overshoot
N8352 series can ensure there is no overshoot in voltage changes under no-load or loading condition, preventing damage to the DUT due to voltage overcharge and over discharge. It can avoid bad effect to product quality. This feature can meet the demand for product test with strict power requirements.



Application--Mobile Test
Most consumer electronics are powered by Li-ion battery, especially smartphones. Battery life issues become prominent. Battery test regulation are becoming stricter. Compared with real battery, it has the following advantages to apply battery simulator. It can emulate the battery change graph and shorten the test cycle. The reliability of test data can be improved by repeated test on a given model.

Both channels of N8352 can charge and discharge. Thus either channel can be used as a power supply, connecting to mobile power terminal. The other channel can be used as a battery, connecting to mobile battery terminal. Both charging and discharging performance can be tested without changing the cables. A single N8352 can be used to test a charge & discharge protection board without additional switches, which greatly reduces the complexity of the test system and improves testing stability and efficiency.

Advantages of battery simulation VS real batteries

1. Suitable for any battery model
2. Static power consumption test
3. Variable internal resistance output function
4. Built-in fault simulation
5. The initial point of battery simulation can be set arbitrarily.
6. Powerful protection functions, without battery safety hazards and risks
