Product Overview

With the continuous advancement of computer, communication, and control technologies—ranging from computers and communication systems to networked control devices, various digital office equipment, lighting control systems, fire‑suppression systems, surveillance systems, and variable‑frequency air conditioners—a severe harmonic environment has emerged, posing a significant threat to the safe and reliable operation of power systems and associated equipment.

Electronic computers, microprocessors, and other electronic devices generally suffer from low insulation strength, stringent requirements for harmonic environments, and poor overvoltage withstand capability. High-order harmonic distortion often causes these highly sensitive electronic systems to experience program errors, data corruption, timing inaccuracies, system freezes, spontaneous reboots, and even permanent damage to electrical equipment, resulting in substantial losses to both work and daily life.

Konstanz Electric has independently developed the cutting-edge “KSTCHPD-2000 Harmonic Protector,” which corrects voltage waveforms distorted by harmonic distortion and effectively absorbs and mitigates electrical noise, resulting in a smoother, cleaner power supply. This not only enhances grid quality but also ensures the reliable operation of connected electrical equipment.

Product model

The KSTCHPD-1000 harmonic protector consumes virtually no power itself, and its harmonic‑suppression function reduces equipment failure rates and machine maloperations, effectively addressing false tripping caused by harmonic distortion. Featuring sinusoidal waveform tracking and voltage‑limiting/level‑clamping capabilities, it mitigates internal surge voltages, suppresses higher-order harmonics, lowers energy consumption, purifies the electrical environment, and extends the service life and enhances the safety of connected equipment.

Product Features

● High current-carrying capacity and a broader range of applications;
● By adopting a four‑star connection, interphase overvoltages are significantly reduced, thereby greatly enhancing protection reliability.
● It employs a dual‑stage, high‑performance nonlinear resistor architecture that leverages complementary advantages, thereby extending the product’s service life.
● The voltage surge coefficient is 1, unaffected by various switching overvoltage waveforms; the overvoltage protection threshold is accurate, and the protective performance is excellent.
● The device features a simple, compact structure; the three phases are either integrated into a single unit or assembled separately according to site conditions, resulting in a small footprint and easy installation.
●It not only exhibits excellent filtering performance against high-frequency interference but also effectively suppresses low-frequency interference.

Low Voltage Power Capacitor

Low-voltage dry-type shunt capacitors are energy‑saving devices used for power factor correction in low‑voltage power systems operating at 50 Hz or 60 Hz. They reduce reactive power losses and improve voltage quality. The KD‑H dry‑type eco‑friendly capacitor is manufactured using advanced German technology in a Class 100 cleanroom environment. Under vacuum conditions of 10–3 bar, the components are heated while protective gas is injected. This process effectively removes air and moisture from within the capacitor, preventing electrode oxidation and localized discharge. Following this sophisticated manufacturing sequence and rigorous factory acceptance testing and quality assessments, the capacitors achieve exceptional stability and an extended service life. Depending on the application, they are available in single‑phase and three‑phase configurations.

Original Imported Low Voltage Capacitor

The original imported MOKN series capacitors are highly popular in the Chinese market thanks to their proprietary technology. During production, these capacitors are filled with nitrogen (N2), and they incorporate a unique SINECUT grooving process along with a distinctive metal‑treatment technique. Moreover, their optimally positioned internal core ensures that the device’s capacitance remains stable even under the severe stress of high‑voltage AC surges and negative pressure conditions. This hallmark feature makes the MOKN series particularly well suited for applications involving controlled equivalent DC currents and surge protection.

Low Voltage Intelligent Capacitor

The KD‑Z series intelligent low‑voltage power capacitors are a next‑generation reactive power compensation device designed for 0.4 kV low‑voltage distribution networks, delivering high efficiency and energy savings, reducing line losses, and improving the power factor and power quality. They consist of an intelligent measurement and control unit, a synchronous switching circuit, a line protection unit, and low‑voltage power capacitors. These units replace conventional automatic reactive power compensation systems that rely on discrete components—such as smart controllers, fuses, composite switches or mechanical contactors, thermal relays, low‑voltage power capacitors, and indicator lights—wired together inside and on the surface of switchgear cabinets. By eliminating the bulky, unwieldy design of traditional systems, this new generation of low‑voltage reactive power compensation equipment offers superior compensation performance, a more compact footprint, lower power consumption, reduced costs, greater cost savings, enhanced flexibility in application, simplified maintenance, extended service life, and higher reliability, thereby meeting the increasingly stringent requirements of modern power grids for reactive power management.

Low-Voltage Anti-harmonicIntelligent Power Capacitor

The KD‑ZLK harmonic‑suppression intelligent power capacitor is equipped with a custom segmented LCD display that provides real-time readings of three-phase bus voltage, three-phase bus current, three-phase power factor, frequency, the number of capacitor banks and their switching status, active power, reactive power, total harmonic distortion of voltage, and capacitor temperature.
