Product Characteristics
1. Refined design volume
– ZK100 VFD compared to peers: same power output, reduced volume by 30%
2. Independent ventilation channel design
– Completely independent air duct design prevents pollutants from entering the electronic components area, improves product protection effect, and adapts to various environments
– The upper chamber side and top surface are designed without ventilation holes, which effectively prevents the entry of pollutants while ensuring temperature rise, and truly realizes upper and lower isolation.
– High loss devices, bus electrolytic capacitors are fully heat dissipated
– Adopts high-speed, double-ball DC fan with long service life
3. Wide range of grid adaptability
– Wide voltage design in compliance with international standards
– Meets the fluctuation range of 220V/380V/480V-15%~+10% including Europe, North America, India and other countries
4. Overcurrent and overvoltage stall suppression
– By self-adjusting the output frequency and output voltage of the inverter, to maintain the DC voltage of the inverter at a fixed level to prevent overcurrent and overvoltage
5. Anti shaking function
– When the power supply suddenly loses, there are two options for handling it.
– It can effectively protect the safety of equipment in some situations where coasting is not allowed.
– In the event of power grid fluctuations or instantaneous power outages, the driver uses a superior under voltage suppression algorithm to ensure that the system can maintain normal operation for the longest time under the same inertia load.
6. Efficient & Energy-saving
– Excellent energy-saving control algorithm, small current and high efficiency.
– Direct drive control, no energy loss from reduction box and gear transmission.
– Under the same load, We zk100N output current is smaller, more energy-saving and more efficient, especially the field weakening area control PK other big brands as show above Fig.
