Hangzhi HZ1035 Single-Phase Programmable AC Standard Source | 120A High Current + 456V Output — A High-Precision Solution Across the Full Range.
Are you encountering these common challenges in electrical testing?
Do you still need an external current booster just to measure 100A?
Is your harmonic testing unable to replicate real-world operating conditions?
Does measurement accuracy begin to drift as test duration increases?
These issues arise almost daily in metrological verification, energy meter testing, and scientific research experiments. Equipment complexity, low efficiency, and unstable results are becoming critical factors that compromise testing quality.

HZ1035: A One-Stop Solution for Three Major Industry Pain Points
Pain Point 1: High-Current Testing is Cumbersome and Unsafe — "Testing 100A Requires Connecting a Stack of External Equipment"
Industry Status Quo
Most standard current sources have an upper limit of only 20A or 50A. When testing 100A energy meters or instrument transformers:
An external current booster is required.
Wiring is complex and prone to errors.
Errors accumulate, leading to unstable results.
High-current operations pose significant safety hazards.
HZ1035 Solution
With a maximum output current of 120A—covering the full range from 0.1A to 100A—no external current booster is needed. The device delivers high current directly upon startup, allowing a single operator to complete the entire testing process.
Simpler wiring
Lower risk
Significantly improved testing efficiency
Pain Point 2: Insufficient Harmonic Testing Capabilities — "The Power Grid is Complex, Yet Equipment Can Only Output Ideal Waveforms"
Industry Status Quo
The proliferation of non-linear loads has made harmonic distortion a prominent issue.
Traditional standard sources support only pure sinusoidal waveforms or a limited range of harmonics.
They struggle to meet the demands of power quality analysis and scientific research applications.
HZ1035 Solution
Supports harmonic output from the 2nd to the 41st order, with adjustable harmonic content (0%–40%) and independent phase settings.
Transitioning from “idealized testing” to “real-world condition testing”
Delivering more valuable insights for power quality analysis
Pain Point 3: Accuracy Drift and Unconvincing Verification Results — "Once Data Becomes Unstable, the Report Loses Credibility"
Industry Status Quo
Open-loop systems or software-based compensation schemes are highly susceptible to environmental influences.
Accuracy drift becomes significant during prolonged testing sessions.
Verification results are prone to disputes and challenges.
HZ1035 Solution
Full-range accuracy for both voltage and current: ±(0.03% RG + 0.02% RD).
Features multi-stage closed-loop PID control for real-time correction of output signals.
Stability is superior to 0.01%/min.
✔ Stable and controllable output
✔ Verification results possess greater authority and credibility
