Key Product Features
Dual AC/DC High-Precision Benchmarking: Delivers three-phase AC parameters (voltage, current, phase, frequency, power) and a comprehensive suite of DC signals (voltage, current, power, and low-voltage outputs for shunts/Hall sensors) from a single unit.
Advanced Harmonic Control (Perfect Fluke 6105A Realignment): Generates 2nd to 51st harmonics with arbitrary combinations of harmonic order, content rate, and phase angle. The phase control perfectly targets Fluke 6105A parameters, enabling precise non-linear load simulations.
Real-Time Waveform & Graphical Display: Captures and displays up to 32 electrical parameters simultaneously on a large color LCD. Supports real-time voltage vector diagrams and harmonic bar graphs, showing Crest Factors (CF), Ripple, and Telephone Harmonic Factors (THFF).
Specialized Waveform Simulation: Outputs non-sinusoidal waveforms including peaked waves, flat-top square waves, triangular waves, sawtooth waves, half-wave signals, and 90° phase-triggered waves.
Triple-Channel Independent Pulse Verification: Equipped with 3 independent energy pulse input/output ports, enabling the system to evaluate errors for up to 3 single-phase or three-phase AC energy meters concurrently.
Dual Open Communication Protocols & Secondary Development: Built-in RS232 and RS485 interfaces with full configurations up to 115200. The system supports both custom manufacturing protocols and the standard MODBUS protocol, completely open for third-party automated system integration.
Industrial Foot-Switch Interface: Built-in remote control ports support external foot-switches to trigger 3U/3I/UI signals instantly, enhancing throughput for assembly line operations and high-volume quality control departments.
Robust Fail-Safe Hardware Protection: Employs smart protection mechanisms that automatically cut off output and trigger pop-up window text alerts and acoustic alarms if a voltage short-circuit, current open-circuit, or incorrect wiring configuration is detected.

FAQ
Q1: How does the harmonic output capability of the MOEORW-WNY98 compare to standard laboratory calibrators?
A1: The MOEORW-WNY98 supports highly configurable 2nd to 51st harmonic injection where harmonic order, content percentage, and initial phase are fully independent. Critically for advanced power quality modeling, its harmonic phase architecture is specifically engineered to perfectly match Fluke 6105A standards, providing high-fidelity distortion simulation at a highly accessible price point.
Q2: What is the benefit of the 4-wire remote sensing connection on the DC voltage output?
A2: Under high-load test conditions, line voltage drops along connecting leads can introduce severe measurement errors. The MOEORW-WNY98 addresses this by offering a 4-wire terminal system (U+/U- for primary driving current, and R+/R- for feedback sampling), allowing the internal amplifier loops to compensate for lead resistance and maintain exact voltage accuracy directly at the device-under-test (DUT) terminals.
Q3: Can this equipment be integrated into a larger automated production line software system?
A3: Yes. The unit is equipped with high-speed RS232 and RS485 communication ports. To eliminate vendor lock-in and minimize development times, the device opens up two protocols: a proprietary manufacture command protocol and a standard industry MODBUS protocol, allowing automation engineers to perform seamless secondary development and SCADA integration.
Q4: How does the device handle protective shutdown if an operator accidentally shorts out a high-voltage connection?
A4: Safety is maintained through hardware and software real-time monitoring. If a voltage short-circuit, current open-circuit, or severe phase miswiring occurs, the internal dual closed-loop system senses the impedance fault instantly, kills all analog outputs within milliseconds, and triggers an acoustic alarm along with an on-screen modal notification.
