IT8500G+ has built in as many as 8 fast charging protocols, meeting the test requirement of fast charging adapters, power banks, fast charging power banks and other products. At the same time, it also has other functions like automatic testing, battery discharge testing, dynamic testing, etc. So it can complete most of the performance testing of switching power supplies, batteries and other product during the development and production stages.
Functions and Advantages
Voltage/current ripple measurement
Ripple is one of the parameters that must be tested for switching power supplies. Excessive ripple may cause interference to the DUT or shorten the life of the DUT. IT8500G+ has a ripple measurement function, and its measurement bandwidth is up to 300kHz, which meets the ripple measurement requirements of switching power supplies or chargers. At the same time, its remote sense function can help to eliminate the impact caused by the voltage drop on the line. No oscilloscope needed, users can just press the ‘down’ button on the front panel to read the voltage ripple value (Vp-p/Vp+/Vp-) and current ripple value (Ipp/Ip+/Ip-) of the DUT directly. This greatly simplifies the wiring and operation process.
Built-in multiple fast charge protocol
The consumption of battery power is getting faster and faster due to more andmore functions generated in mobile phone. Fast charging technology can helpto improve user experience under the situation. IT8500G+ has built-in multiplefast charging protocols (QC2.0, QC3.0, PE+, PE2.0+, USB PD2.0,USB PD3.0,F CP, SCP) which can complete the test for adapters with different protocols.Users can quickly choose the charging protocol on the menu. And in automatictest mode, it can realize the performance verification of the fast chargingadapter under different charging process, like no-load voltage, short-circuitcurrent, constant voltage and constant current.

Multi-channel
The multi-channel mode of IT8500G+ is specially designed for optimizing system integration. Through this mode, it can easily build hardwareplatforms with dozens or even hundreds of channels. It simplifies communication connections. There is no need to purchase expensive communication modules or communication interface expansion cards (such as USB hub, multi-serial card or switch), which greatly saves test costs. Themulti-channel mode of IT8500G+ allows up to 16 units connections. This means that only one communication line is required to connect to the PC forevery 16 electronic loads. Let us take the 60-channel burn-in test as an example, if you use the multi-channel mode of IT8500G+, it can save thecost of 8 expansion switches, which presents you an more efficient ATE solution.
