Why Choose ZHIMING's Input & Cutout Reactor?
Broad Voltage & Current Coverage
The DCL Series Input & Cutout Reactor supports rated voltages from 400V to 1200V and rated currents from 3A to 1500A, covering small drives up to heavy industrial converters. This wide operating envelope allows a single product family to serve diverse DC link applications without sourcing from multiple suppliers.
Effective Harmonic Mitigation & Equipment Protection
Installed in the DC link of inverters and converters, this reactor suppresses capacitor-induced harmonic distortion in the input current, reduces DC bus AC ripple, and protects the rectifier bridge and capacitors from surge-current damage. The result is longer equipment life and fewer unplanned shutdowns.
High Dielectric Strength & Thermal Reliability
With 3000V AC dielectric strength between core and winding, insulation resistance exceeding 100MΩ at 1000V DC, and Class F insulation rated above 155℃, the DCL Series Input & Cutout Reactor is built to withstand the electrical stress and heat of continuous DC link operation in demanding industrial environments.
Low-Noise, Compact Design
Operating below 35dB at one meter, the DCL reactor is quiet enough for control rooms and operator-adjacent installations. Its space-efficient footprint — ranging from 100×120×85mm for small models to 230×250×320mm for the largest — simplifies panel integration while leaving room for wiring and ventilation.
PERTANYAAN YANG SERING DIAJUKAN
Where is the DCL Series Input & Cutout Reactor installed in a drive system?
The DCL Series is a DC-side reactor installed in the DC link of inverters, converters, and variable frequency drives — between the rectifier bridge and the DC bus capacitors. It is not a line-side (AC input) or motor-side (AC output) reactor.
What is the main function of this Input & Cutout Reactor?
The primary function is to mitigate capacitor-induced harmonic distortion in the input current, reduce DC bus AC ripple, and protect the rectifier bridge and DC capacitors from surge currents that can cause overheating and premature failure. It also improves the input power factor and restricts transient voltage changes.
What voltage and current range does the DCL Series cover?
The DCL Series covers rated voltages from 400V to 1200V at 50Hz, with rated currents from 3A to 1500A (measured at 40℃ ambient). The specification table includes 23 standard models matched to motor adapters from 0.75kW to 450kW.
What is the IP00 protection rating — does it need a special enclosure?
IP00 means the reactor has no protection against solid objects or water and must be installed inside a protective enclosure such as a control cabinet or switchgear panel. This is standard for panel-mounted inductive components designed for indoor industrial use.
Can I order a custom DCL Reactor with non-standard inductance or current ratings?
Yes. The specification table lists typical models, but ZHIMING can design and produce DCL reactors with custom inductance values, current ratings, voltage ratings, and mounting dimensions. Contact the manufacturer directly with your specifications for a tailored solution.
