Product introduction:
The DKLN-1 power quality test analyzer intelligent calibration instrument is a joint development of Nanjing Dandick Science and Technology Development Co., Ltd and Shanghai Lianneng Instrument Co., Ltd. The design of this instrument is according to the national standards such as GB/T14549-2008, GB/T12325-2008, GB/T12326-2008, GB/T15543-2008, GB/T15945-2008 and it's also according to the Electric Power Industry Standard DL/T1028-2006.   The instrument is designed by a lot of advanced technology such as DSP, DDS waveform synthesis, CPLD and broadband amplifier (no PT, CT). The product is designed with high integration, small size and light weight, so it's easy and convenient to use. It has a leading technology and high cost-effective. Our product fill up the gaps in China and it can replace the imported. It's able to calibrate and test any power quality test analyzer according to the "A" level standard. This product is identified by the provincial level, it's the first instrument in this area in China and it's also advanced throughout the whole world.
With the help of the DKLN-1 power quality test analyzer calibration device, users can synthesize a lot of irregular standard signals such as the voltage, current harmonic, inter-harmonic, modulated harmonic, flicker and swells/sag , our product is an ideal instrument for power users to power quality test analyzers.
 
Main Features:
●    Designed by broadband standard source, the output of standard flicker and inter-harmonic at any frequency or amplitude;
●    This device is able to test a number of functions of the power quality test analyzer such as the voltage, current, frequency, harmonic, inter-harmonic, flicker, swells/sag and three-phase unbalanced degree.
●    Output standard harmonic 2-63 times, can single or arbitrarily superimposed multiple harmonic wave output, accurate real-time display the content, phase, active power, reactive power of any harmonic.
●    Produce signals with high accuracy according to national standards such as standard flicker, inter-harmonic and swells/sag.
●    The voltage, current, harmonic, inter-harmonic, flicker, swells/sag of each phase is under control of security independently.
