The ATE / ATS Multi-Channel Power Supply Tester (4 / 8 channel) is a multi-channel automatic test system developed by TAOKE (Dongguan Taoke Electronic Co., Ltd.) for volume production testing of power supply products. One machine serves many purposes: it supports power banks, power adapters, car chargers and wireless chargers, is compatible with the latest C94 chargers and USB auto-adaptation, and integrates a high-precision programmable power supply with a programmable electronic load — meeting both the supply and load requirements of power products at the same time and enabling multi-channel individual or collaborative (linked) testing.

1. Product Overview

Housed in an industrial test cabinet, the system integrates 4 / 8 test channels, a programmable power supply, a programmable electronic load, a power meter, a high-voltage insulation tester, an AC power source and a pneumatic test fixture, all operated through the built-in industrial PC and its large touch screen. By selecting the test profile (part number) for a given product, the operator can complete the whole flow — start-up self-check, loading, automatic testing, result judgement and burn-in testing — for fast changeover and simple operation on the production line.

Main functions: multi-channel individual / linked testing, compatibility with a variety of interfaces (Lightning, Type-C, Micro, USB), fast-charging protocol activation (QC2.0 / QC3.0 / QC4.0, USB PD, VIVO, OPPO, etc.), on-load voltage and current testing with over-current / short-circuit protection, DC / AC conversion efficiency and ripple measurement, AC static power consumption detection, four-channel left / right rotation testing, USB auto-adaptation, single-port charge / discharge of Type-C power banks, and volume-production burn-in testing.

5. Test Software and Operation

The test software runs on the built-in industrial PC and is operated through the large touch screen. Its main menus are File / Edit / Data / Start Test / Stop / Reset / Exit. On start-up the machine automatically performs a reset and self-check and loads the part number that was open when it was last shut down.

The operator selects the test profile for the product under test via “File — Open Part Number” and starts testing; the interface shows each channel’s test items, measured values and pass / fail results in real time. To add or modify test items, use “Edit Part Number” to add, insert, delete or move items and to set upper / lower limits, with whole-block copying between channels; saving the part number completes the edit. Engineer-level functions include temporarily disabling a channel and cyclic burn-in testing.

6. Typical Applications

• Volume testing of charging products: car chargers, direct chargers, power banks, wireless chargers and other charging products.
• Single-channel output products: four can be measured simultaneously (eight on the 8-channel model).
• Dual-channel output products: two can be measured simultaneously (four on the 8-channel model).
• Multi-channel output products: three- and four-channel products can be measured in a single pass.
• Fast-charging and universal products: QC2.0 / QC3.0 / QC4.0, USB PD, VIVO, OPPO and other fast-charging products, plus Lightning, Micro and other universal products.
• TWS charging-case PCBA testing: together with an 8-channel fixture and simulated battery instruments, it performs multi-state automatic testing of TWS charging-case PCBA (static, case charging, earbud charging).
