Product Specification: TO-VAH Single-Phase Digital Display Meter
The TO-VAH Single-Phase Digital Display Meter is a high-performance, user-friendly electrical measuring instrument designed for accurate real-time monitoring of single-phase AC electrical parameters. Tailored for industrial control panels, household distribution boxes, and small-scale power monitoring systems, it combines precision, durability, and easy installation to meet diverse electrical measurement needs.
Core Technical Parameters
Measuring Voltage Range: AC 40V ~ 500V
Covers a wide spectrum of single-phase AC voltage inputs, making it suitable for both low-voltage auxiliary circuits (e.g., 110V, 220V household power) and medium-voltage industrial auxiliary systems, ensuring stable measurement without signal distortion.
Measuring Current Range: 0 ~ 100A
Supports high-precision current detection for most single-phase electrical equipment, from small appliances (e.g., refrigerators, air conditioners) to light industrial machinery, providing reliable data for load monitoring and energy management.
Rated Frequency: 0 ~ 99Hz
Adaptable to global power frequency standards (e.g., 50Hz for Asia/Europe, 60Hz for North America) as well as special low-frequency or high-frequency applications, ensuring consistent performance across different power grids.
Measurement Accuracy: Class 1.0
Complies with international accuracy standards, guaranteeing that measurement errors remain within ±1.0% of the full-scale range—ideal for scenarios requiring precise data, such as energy auditing, equipment maintenance, and power quality analysis.
Installation Method: DIN Rail Mounting
Features standard DIN rail compatibility (fits 35mm DIN rails commonly used in electrical enclosures), enabling tool-free, space-saving installation and easy integration with other rail-mounted components (e.g., circuit breakers, contactors).
Storage Temperature: -25℃ ~ +70℃
