GENY Electric Co., Ltd. Power Source Series, The YCS-103 Three-Phase Standard Power Source is manufactured in compliance with the national standard GB/T 11150-2001 Test Equipment for Electricity Meters, mainly used in electric energy meter calibration systems.
This standard power source integrates a digital synthesized sinusoidal signal source, high-stability power amplifier, automatic overload protection circuit, current/voltage output conversion circuit, and working power supply circuit. Adopting advanced digital signal synthesis technology with a single-chip microcomputer and high-performance logic array as the core, it generates high-precision sinusoidal signals with adjustable frequency from 45.000Hz to 65.000Hz and phase from 0° to 360°.
The output voltage, current, phase and frequency can be precisely controlled via the panel keyboard or PC software. The device features low waveform distortion (<0.3%), high output stability, and complete protection functions including overcurrent, voltage short-circuit and current open-circuit protection. It supports both automatic calibration via RS-232 communication and manual operation via the panel keyboard, making it an ideal standard power source for electric energy meter verification and testing.
