Product Introduction

XL-803F/H Three-Phase Programmable Standard Power Source It is a new generation high-precision standard power source based on 1.2 G MAC DSP, large-scale FPGA, high-speed high-precision DA, and high-fidelity power amplifier. It is suitable for power departments and enterprises that require measurement, inspection, and high-precision standard signal sources in power system electrical measurement, thermal engineering, remote control, dispatching, etc. It is also suitable for other occasions that require high-precision standard signal sources for measurement and inspection.

Main Features  

• Can output pure sine power signals with distortion as low as 0.03% (typical value).
• Can superimpose various harmonics on the fundamental frequency output.
• Frequency output adjustable from 40Hz to 65Hz with a resolution of 0.002Hz and accuracy of 0.002Hz.
• Phases A and B share one frequency reference, while phase C has a separate frequency reference, enabling phase shifting and frequency conversion.
• Phase adjustable from 0 to 360 degrees, conveniently simulating various power supply conditions, including reverse power flow scenarios.
• Strong load capacity, capable of driving capacitive, inductive, resistive, or composite loads, with load regulation better than 0.01% RG.
• Excellent temperature stability; core components are military-grade products with temperature coefficients as low as 1 PPM, ensuring output accuracy even in outdoor temperature environments.
• Uses 32-bit MCU + DSP processor, powerful and flexible functions.
• Power frequency waveform synthesis with up to 50,000 points per cycle; internal signal output requires no smoothing filter, ensuring precise waveform output, enabling accurate harmonic output and excellent harmonic distortion performance.
• Convenient connection to PC via RS232 for extended functions.
• Comprehensive protection against overcurrent, overvoltage, overheating, short circuit, open circuit, and overload.
• Hardware PID with extremely fast response; load changes do not cause any output fluctuations.
• 1024*700 LCD display with Chinese interface, simple operation.
• Open communication protocol, facilitating secondary development (automatic factory calibration for RTU/FTU/power management terminals/public transformer metering terminals).
• Can drive purely capacitive loads; combined with PC software, it can test electric energy meters.
   

Main Functions

• AC Standard Source Output: Can output high-precision voltage and current with adjustable frequency (40Hz–65Hz), phase, and amplitude, convenient for power workers' development and calibration.
• Transmitter Calibration: Used for voltage, current, and power calibration.
• Communication Function: Used for communication with PC and other main control modules; only supports the "Programmable Power Supply Interface Protocol."
• Electric Energy Verification Function: Used to verify electric energy pulse input.
• Phase-Shifted Frequency Output: Phases A and B frequencies are uniformly adjustable; phase C frequency is independently adjustable, convenient for users needing two frequencies, such as synchronization devices in power protection.
• User-Defined Function: Users can define function outputs, but functions must not contain DC components.
• Secondary Development: Users can refer to the "Programmable Power Supply Interface Protocol" to develop various functions via the communication port.
• Software Control Function: Equipped with XL-1100 series operation software; once the device power is on and communication cable connected, it can be freely controlled on a PC, convenient and fast.
• Alarm Function: When the device encounters an abnormality, the system automatically activates protection programs with sound or interface pop-up prompts. Users should power off to find and eliminate faults, such as voltage-to-ground short circuit or current open circuit output.
