Voltage Adjustment Range | Educational labs, small-scale testing | LY-909C: 2–12V (±0.5% accuracy) Industry Standard: 0–30V (±1% accuracy) Advanced: 0–30V (±0.1% accuracy) ▲ | Precise for low-voltage experiments; cost-effective for educational use. | Limited to 12V max; less flexibility for industrial/high-power applications. |
Output Current Capacity | Low-power devices, basic electronics | LY-909C: 5A max (ISO 60950-1 compliance) Industry Standard: 10A+ (for industrial use) Advanced: 10A ▲ (handles higher loads) | Sufficient for most lab equipment; safer for small devices. | Struggles with high-current demands (e.g., motors, heaters). |
Display and Control Precision | Real-time voltage monitoring | LY-909C: Digital display (±0.1V resolution) Industry Standard: Analog dial (±1V) Advanced: Touchscreen + 0.01V resolution ▲ | Clear, numeric readout for accuracy; easy knob adjustment. | No touchscreen; lacks advanced data-logging features. |
Safety Features | Safety-critical environments | LY-909C: Overcurrent protection, reset button (IEC 61010-1) Industry Standard: Short-circuit protection + thermal cutoff Advanced: Dual-layer protection + remote monitoring ▲ | Basic safety for classroom use; prevents accidental overloads. | Lacks advanced protections (e.g., arc fault detection). |
Portability | Fieldwork, mobile labs | LY-909C: Compact (15cm×10cm×5cm), 0.8kg ▲ Industry Standard: Benchtop units (2–5kg) Advanced: Ultra-light (0.5kg) ▲ | Easy to carry; ideal for on-site testing. | Less durable than ruggedized industrial models. |
Input Voltage Compatibility | Global use (220–240V regions) | LY-909C: 220–240V AC (50Hz) Industry Standard: 110–240V universal input Advanced: Auto-switching 110–240V ▲ | Reliable in most countries with 220–240V grids. | Requires adapter in 110V regions (e.g., North America). |
