Description
The GDSL-A-5000A 10V is a professional-grade, general-purpose single-phase digital high current generatorexclusively designed for short-duration high current tests, current transformer ratio and polarity verification, protection relay calibration and low-voltage circuit breaker testing in power systems, electrical manufacturing and industrial enterprises. It fully complies with GB/T 14048.1-2023, GB 7251.1-2013 and IEC 60947-1:2020 standards, adopting an innovative split modular design that separates the control console and current booster, both equipped with universal wheels and brakes for easy on-site transportation and deployment.
The instrument features a high-efficiency toroidal current booster with low loss and high output efficiency, delivering 0-5000A single-phase continuously adjustable large current output with ±1% measurement accuracy and 0.2% current stability. The 10V high output voltage enables it to drive longer distance high current cables and higher impedance loads, solving the problem of insufficient current output of traditional 6V generators in long-distance test scenarios. The output waveform is a standard sine wave with distortion ≤3%, meeting the strict requirements of international standards for test waveforms. The built-in 0.2-class high-precision true RMS current transformer eliminates the need for external standard meters, ensuring accurate and reliable measurement results.

FAQ
Q: What is the advantage of 10V output voltage compared to traditional 6V generators?
A: The output voltage of a high current generator determines its ability to drive load impedance. According to Ohm's law (I=V/R), for the same output current, higher voltage can drive higher impedance loads. This means GDSL-A-5000A 10V can:
- Drive up to 50m long high current cables (compared to 20m for 6V generators)
- Test equipment with higher connection resistance
- Provide more stable current output in long-distance test scenarios
- Reduce power loss in cables, improving test efficiency and accuracy
Q: How does the automatic CT ratio and polarity test work?
A: GDSL-A-5000A has a built-in secondary current measurement channel (0~5A). When testing a current transformer:
- Connect the primary side of the CT to the output of the generator
- Connect the secondary side of the CT to the secondary input terminal of the instrument
- Set the rated ratio of the CT in the instrument menu
- Start the test, the instrument will automatically output a stable current
- The instrument will simultaneously measure the primary current and secondary current
- Automatically calculate and display the actual ratio and judge the polarity (positive/negative)
Q: How long can the equipment operate continuously at rated current?
A: GDSL-A-5000A can operate continuously for 5 minutes at 5000A rated current with the built-in forced air cooling system. For currents ≤2500A, it can operate continuously for an unlimited time. For longer duration tests at rated current, we recommend using our GDSL-D series long-duration high current generators.
