Type Recommendation
Wide Range of automatic measuring range
Under constant output power limit, automatic switching of voltage and current range, which can output large voltage when small current, and large current when small voltage, provides a wider output range; A power supply can achieve a variety of voltage and current combination, greatly improving the utilization of power.
Step Mode (Sequence programming)
The device supports a maximum of 50 sequences. The user can edit each step function according to the actual needs, and make the device output in constant voltage and constant current mode in sequence to meet the specific test requirements.
Charging Mode
Charging mode is suitable for charge and discharge aging test of different electric energy storage media such as lithium battery and capacitor. Set up a maximum of 10 steps to support charging sequence, each step can be independently set voltage/current reference value and judging conditions to determine whether to go to the next step, can simulate the fine charging curve.
Function generator mode
The Function generator mode produces regular waveforms such as sine, triangle, sawtooth, rectangle , pulse and Zigzag, as well as a combination of the above waveforms, and overlays the edited waveforms on top of the output voltage or current. The default function will provide the user with all the necessary parameters, such as the benchmark, the number of cycles, waveform amplitude, time and a complete set of configuration parameters.
Note: the falling waveform part of the waveform needs to be guaranteed by load discharge
Remote Compensation
This function is used to compensate the voltage drop on the load line to improve the test accuracy. When using the remote compensation function, remove the two short terminals and connect the PIN1 and PIN4 to the load positive and negative Poles (PIN2 and PIN3 suspended) respectively. The maximum compensation voltage is 5% of rated voltage, the output power should be less than 1.05 times of the rated power.
Parallel Function
This series of power supply support master/slave Parallel mode. In parallel mode, the current sharing function equalizes the output power of the power supply in the system, so that the extended power can be guaranteed without affecting the performance of the power supply. CAN parallel mode to achieve the same dynamic response as single machine, to achieve high-speed master-slave synchronous response without delay.
Note: 120 ohm is the CAN bus terminal resistor.
