JH150V240A-1.2kW Programmable DC Electronic Load
1. Supports seamless switching between Chinese and English without affecting the load‑carrying state. 2. In dynamic mode, the electronic load can switch between two sets of parameter settings according to predefined rules, while the power supply’s regulation accuracy and transient response are monitored by observing its output voltage waveform under varying combinations of high and low current levels, duration, and slew rates. 3. In dynamic operation, the current rise slope is adjustable, and the current rise/fall slopes can be fine‑tuned in any mode. 4. In addition to specialized measurement functions, it offers a full range of standard operating modes: CC/CV/CR/CP/OCP/LED/Battery/EFFC/Timing. 5. Features a built-in independent ripple‑sampling circuit that accurately measures ripple voltages up to 2 V within a 20 MHz bandwidth, enabling it to partially replace an oscilloscope for ripple analysis or to perform standalone measurements without connecting to the device under test.

I. Characteristics
1. Supports seamless switching between Chinese and English without affecting the loading status.
2. In dynamic mode, the electronic load can switch between two sets of configured parameters according to predefined rules, while the power supply’s regulation and transient response are monitored by observing its output voltage waveform under varying combinations of high and low current levels, duration, and slew rates.
3. In dynamic mode, the current rise slope is adjustable, and the current rise and fall slopes can be configured in any operating mode.
4. In addition to specialized measurement functions, it also supports a variety of standard operating modes: CC/CV/CR/CP/OCP/LED/Battery/EFFC/Timing.
5. Built-in independent ripple‑sampling circuit; ripple voltage remains below 2 V, and accurate sampling is achieved across a 20 MHz bandwidth. It can partially replace an oscilloscope for ripple measurement and can also be used independently to measure without connecting the power supply under test.
