If you are looking for a compact frequency inverter for driving asynchronous motors and need real Modbus RTU, vector control and an integrated brake chopper, the Kinco KC100 offers a cost-effective solution without compromises on functionality or reliability. With power ratings from 0.4 to 5.5 kW, the KC100 covers most standard applications in mechanical engineering and automation — single-phase 230 V or three-phase 400 V. 🏭 Typical Applications Pumps & fans with PID control: The integrated PID controller enables simple pressure regulation, flow control or temperature management — without external controllers. Frequency setpoint via analog input 0–10 V or 0–20 mA. Conveyor technology and series machines: The S-curve ramp provides smooth acceleration and deceleration — ideal for positioning tasks or high-inertia loads such as conveyor belts and winding drives. Integration into Modbus RTU networks: Unlike its predecessor CV20, the KC100 uses real Modbus RTU (RS-485) with standard function codes — it integrates seamlessly into existing PLC architectures and can be parameterized via a higher-level controller. Systems with unstable mains voltage: The AVR voltage regulation actively compensates for mains fluctuations — useful in industrial networks with poor power quality or unstable supply. ⚙️ Improvements Over the CV20 Predecessor Kinco developed the KC100 (introduced 2024) as a targeted upgrade to the CV20 series, passing on cost reductions in power electronics directly to customers: AVR voltage regulation for active compensation of mains voltage fluctuations Vector control (SVC) — 150% rated torque from 0.5 Hz, speed control range 1:200 S-curve ramp for smooth acceleration and deceleration, four ramp groups selectable Integrated brake chopper for braking high-inertia loads (external braking resistor connectable) Autotuning of motor parameters for improved running smoothness Speed tracking — detects current motor speed and enables flying start from the actual speed Power dip ride-through (Instantaneous Non-Stop) — during a mains dip, the drive feeds back kinetic motor energy to maintain operation briefly without tripping Wave-by-wave current limiting — limits current pulse-by-pulse during sudden load spikes, preventing nuisance trips without requiring intervention from the higher-level controller Real Modbus RTU (RS-485) with standard function codes — the CV20 used proprietary function code 41 for permanent parameterization Maximum frequency 600 Hz for high-speed applications Demand-controlled fan speed instead of continuous operation — extends fan service life Spring-clamp terminals on the I/O terminal for fast wiring in series production Extension port (CN2) for external operator panel — cable up to 10 m, parameter copy between drives supported The following functions are also available (as with the CV20): Frequency setpoint via frequency table with 8 fixed values using 3 digital inputs Frequency setpoint via analog input 0–10 V and 0–20 mA Frequency setpoint via Modbus RTU and integrated PID controller Frequency setpoint via pulse input up to 50 kHz ⚠️ Known Limitations No integrated EMC filter: An external EMC filter is required for CE-compliant operation in European installations. Suitable filters for each model are available separately. 🔌 Connections & I/O 4 digital inputs (DI1–DI4): NPN/PNP compatible, active level 9–30 V. DI1–DI3 are standard inputs; DI4 can also be used as a high-speed pulse input up to 50 kHz. 1 analog input (AI): 0–10 V or 0–20 mA, switchable via DIP switch. Internal 10 V reference voltage (+10V terminal) available. 1 digital output (DO): Open-collector, pulse output up to 50 kHz. Can output physical quantities such as set frequency or output frequency. 1 analog output (AO): 0–10 V or 0–20 mA, switchable via DIP switch. 1 relay output (TA/TB/TC): Normally open (TA–TC) and normally closed (TA–TB), switching capacity 3 A / 250 V AC or 1 A / 30 V DC. RS-485 (Modbus RTU): Client/Server for parameterization and control via PLC or PC. Extension port (CN2): For external NETKEY operator panel with up to 10 m cable length and parameter copy function. 🔧 Ratings & Installation Protection class IP20, wall-mounted. Housing width from 65 mm — independent air duct separates cooling air from electronics, enabling 20% more compact design compared to the previous generation. Overload capacity: 150% rated current for 60 s, 180% for 3 s — sufficient for heavy starting loads and short peak demands. Operating temperature: −10 °C to +50 °C (derate above +40 °C: 1% per 100 m altitude or per degree). Storage temperature: −25 °C to +70 °C. Minimum clearances: 100 mm above and below, 25 mm left and right for adequate ventilation. Weight: 0.85 kg (single-phase 0.4–1.5 kW) · 0.90 kg (three-phase 0.75–1.5 kW) · 1.20 kg (single-phase 1.5–2.2 kW) · 1.30 kg (three-phase 2.2–5.5 kW). 🚀 Quick Start Guide & Commissioning A guided online guide is available for quick commissioning — with step-by-step parameterization for motor parameters, control source, frequency setpoint and Modbus RTU: → Kinco KC100 Quick Start Guides 🏷️ Manufacturer and Reliability Kinco Automation is an established manufacturer with many years of experience in developing frequency inverters, HMI and drive technology for the global industrial market.
