Full standard compliance · Four-quadrant operation · Ultra‑low distortion

Wide frequency, high controllability · Integrated stability

Background

In the aviation industry, airborne electrical systems have always been held to extremely stringent requirements for power supply stability, waveform purity, and immunity performance. International and domestic aviation standards such as MIL‑STD‑704F, GJB 181 series, RTCA/DO‑160G, and HB 20326.8 impose clear mandatory specifications for ripple, harmonics, transient behavior, and load response of airborne DC power supplies. For 14V/28V airborne power systems, a high‑precision, full‑featured, standards‑compliant power supply characteristics test system has become essential for avionics development, type approval, and verification.

Technical Challenges

Airborne power supply testing has long faced multiple technical challenges: incomplete standard coverage – unable to simultaneously meet Chinese military, US military, and civil aviation standards; limited waveform simulation capability – difficulty reproducing complex airborne power disturbances; high voltage distortion and poor ripple suppression under high‑current, high‑power conditions; insufficient four‑quadrant load capability – cannot accurately simulate real load characteristics; and low test automation – cumbersome data tracing and report generation.

Solution

3CTEST PDG 08C Series (PDG 08C05 / PDG 08C10) is built on a real‑time processor platform with an integrated design, fully meeting aviation DC power supply standard requirements. With ultra‑low distortion, wide frequency output, four‑quadrant operation, and remote adaptive compensation, it provides a one‑stop, high‑precision solution for airborne power supply testing.

Key Product Advantages

Full aviation standard coverage

One‑stop compliance testing perfectly meets MIL‑STD‑704F, GJB 181 series, RTCA/DO‑160G S16/S18, and HB 20326.8 DC (LDC) requirements, supporting all tests for 14V/28V airborne systems. One system meets multiple standard validations.
Two power ratings on the same platform for flexible selection:

• PDG 08C05: ±50A / 4kW

• PDG 08C10: ±100A / 8kW

High voltage/current accuracy, resolution down to 0.01V/0.01A, suitable for testing airborne equipment of different power levels.

Ultra‑low distortion + wide frequency output

High waveform fidelity: output voltage distortion<0.3%, wide frequency coverage DC ~ 200kHz; extremely low ripple noise: Vrms ≤ 0.05V, Vpp ≤ 0.2V, perfectly reproducing true airborne power supply characteristics.

Harmonics + ripple closed‑loop + arbitrary waveform

Full simulation support: harmonic output (0~20V), ripple closed‑loop testing; built‑in arbitrary waveform generator for editing complex waveforms; supports full‑power four‑quadrant load, accurately simulating various airborne power consumption conditions.

Remote compensation + multiple protections

Stable and reliable: Remote compensation adaptive function eliminates line drop effects; built‑in comprehensive protections including overcurrent, overvoltage, undervoltage, over‑power, overtemperature; Ethernet RJ45 remote control, with CoreLab software for automated testing and report generation.

Integrated industrial design

Easy deployment: 5.7‑inch TFT touch screen for intuitive operation; industrial‑grade aviation connectors and terminal blocks; robust and reliable, suitable for demanding aviation laboratory environments.
