This manual introduces the DL-2000A large current generator's product features, usage methods, precautions and other content.
The DL-2000A large‑current generator, produced by Qingdao Sifang Taihe, uses an energy‑saving autotransformer and high‑permeability current‑raising unit. It features a 0.5‑class digital meter with true‑RMS indication and an optional digital time‑counter, making it suitable for testing current transformers, protection devices and secondary circuits in power systems.
The manual describes the main technical parameters, step‑by‑step usage instructions, safety measures, and warranty conditions. It also provides guidance on proper connection, adjustment of output current, and precautions to avoid overheating during prolonged operation. This manual is written in Chinese.

|---|---|
| Output voltage | Single‑phase AC0‑5V |
| Output current | Single‑phase AC0‑2000A |
| Display | Digital meter display |
| Time measurement | Customizable digital time‑counter |
Turn the autotransformer clockwise evenly until the digital current indicator shows the desired large current.
No. The device is designed for short‑time operation and must not run at rated current for long periods to avoid overheating.
Connect a standard ammeter (or external transformer) to the chassis to ensure measurement accuracy before testing.
Return the autotransformer to the zero position, disconnect the power, and only then remove the test wiring.
