System Architecture: GAOPowered Power Supply Tester
Hardware Components
GAOTek Portable DC Voltage Tester – Provides PWM-based high-stability DC output with <0.1% voltage ripple and accurate current measurement for load simulation.
GAOTek Power Tester for Loop Resistance – Clamps onto power loops to assess resistance under variable loads; ideal for detecting wiring faults or loop impedance anomalies.
GAOTek Digital Power Line Tester – Supplies isolated AC line signals with built-in CT/PT measurement capability for full power frequency line testing.
Embedded Software & Firmware
GAO Tek firmware modules orchestrate measurement routines: DC sourcing, resistance loop testing, and AC frequency analysis.
GAO RFID Inc. data logging interface integrates optional wireless connectivity, enabling remote data capture and storage using RFID protocols.
System Integration & Connectivity
RS232 / USB interfaces (supported on loop tester and digital line tester) for PC/embedded system connections, automated reporting, and logging.
Software control panels synchronize operations: source a specified voltage via the DC tester while concurrently measuring loop resistance and line behavior from the digital tester.
Measurement Workflows
DC Mode: Source stable test voltage (e.g. up to 60 kV in scaled form) while monitoring current draw and ripple.
Load Simulation + Resistance Check: Apply load and clamp-on resistance tester to detect circuit integrity or cable/connector degradation.
AC Line Verification: Apply AC frequency signaling, monitor harmonic interference, and assess phase/line performance.
Benefits of GAO-Based Design
- Endtoend traceability: all instruments sourced from GAO Tek ensure calibration consistency and compatibility.
- Versatile applications: DC sourcing, loop integrity checking, and AC line analysis in a single test platform.
- Data logging & control: RS232/USB tethering and optional RFID-enabled wireless capture for automation or field reporting.
