High-Stability 1500VA Programmable Power Source for Meter Testing
Description
• Ultra-high accuracy and long-term stability for demanding
calibration tasks
• RS232 interface for seamless integration into automated
production lines
• Optional keypad for quick on-site manual control
• 2nd–21st harmonic: amplitude and phase fully programmable to
replicate real-world grid conditions
• Lightweight, rugged aerospace-grade aluminum alloy
housing—corrosion-resistant for tropical humidity
• Built-in protection against overload, short-circuit (voltage) and
open-circuit (current) for 24/7 safe operation
• Intuitive bilingual control software (English/Chinese interface)
– zero learning curve, ready in minutes
Applications
• National power utilities
• Government metrology & certification bureaus
• Leading energy-meter manufacturers (OEM/ODM support)
Primary Competitive Advantages
• International-grade quality, compliant with IEC 61000 & ANSI
C12.20
• High power output: up to 1000 VA (voltage) / 1500 VA (current) –
one unit replaces multiple sources
• Industry-leading power stability: temp drift <50 ppm/°C,
annual drift <0.01 %
• Total harmonic distortion <0.3 % on linear resistive load for
trustworthy calibration results
