通道数Channels	4
单路输出路径能力Per-port output path	最高 4 A；不代表协议保证的充电电流up to 4 A; not a guaranteed charging current
CDP 充电CDP charging	USB BC 1.2 CDP，单口最高 1.5 A；不支持 QC、USB PD 等快充协议USB BC 1.2 CDP, up to 1.5 A per port; QC, USB PD and other fast-charging protocols are not supported
电压/电流测量V/I measurement	每路标配。电压：0–5.5 V，1.48 mV 分辨率，精度 ±（读数的 0.91% + 36 mV）；电流：0–4.0 A，1.15 mA 分辨率，精度 ±（读数的 2.5% + 50 mA）standard on every channel. Voltage: 0–5.5 V, 1.48 mV resolution, ±(0.91% of reading + 36 mV). Current: 0–4.0 A, 1.15 mA resolution, ±(2.5% of reading + 50 mA)
测量数据流Measurement stream	最高 100 Hzup to 100 Hz
过流保护Overcurrent	每路自恢复保险丝resettable fuse on every port
数据线控制Data-line control	USB 2.0 D+ / D−，独立于电源USB 2.0 D+ / D−, independent of power
工作模式Operating modes	普通 / 互锁；上电默认状态、断电恢复、设备地址normal / interlock; power-on defaults, power-loss recovery, device address
供电（USB-C）Power inputs	DATA、CMD 与 AUX POWER 三路 5 V 输入合并供电；总输入电流须低于 10 A，实际输出取决于电源、线材与散热。AUX POWER 外接电源必须具有限流和短路保护combined 5 V input from DATA, CMD and AUX POWER; total input current must remain below 10 A, and available output depends on the supplies, cables and cooling. The external AUX POWER supply must provide current limiting and short-circuit protection
输入电压限制Input-voltage limit	仅限稳压 5 V DC（推荐 4.75–5.25 V）；5.5 V 为绝对最大值，禁止输入 9 V、12 V、15 V 或 20 Vregulated 5 V DC only (4.75–5.25 V recommended); 5.5 V is the absolute maximum—never apply 9 V, 12 V, 15 V or 20 V
主机接口（USB-C）Host interfaces	USB-C DATA 上行数据口 + USB-C CMD 指令口（USB CDC）USB-C DATA upstream port + USB-C CMD control port (USB CDC)
固件升级Firmware update	支持Supported
USB CDC 主机支持USB CDC host support	当前 Windows、macOS、Linux 通常使用系统内置驱动；Windows 7 需使用随软件提供的驱动current Windows, macOS and Linux systems normally use built-in drivers; Windows 7 uses the bundled driver

两个版本功能相同，仅是否随附电源适配器不同。Both variants provide the same control and measurement features; only the bundled power adapter differs.
