The frequency converter is an electric energy control device that uses the on-off function of power semiconductor devices to convert industrial frequency power into another frequency. The application field of the frequency converter covers many industries in the economy. Due to the advantages of high speed regulation accuracy, advanced technology, rich functions, high reliability, simple […]

Power Inverter is a device that converts industrial frequency power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize variable speed operation of motor. The control circuit completes the control of the main circuit, the rectifier circuit converts AC power into DC power, the DC intermediate circuit smoothes and filters the

The customer needs an intermediate frequency power supply that can produce a rated voltage of 4500VAC, 100~450V continuously adjustable, ZONCN provides the solution as follows.   Medium voltage IF power supply is a kind of power supply equipment which converts electric energy into IF electric energy within a specific frequency range, its working principle is

Customers need new, advanced, mature, complete and safe and reliable, and the technical and economic performance of the equipment. High economic performance of the frequency control cabinet, including, but not limited to: inverter power unit cabinet; feeder and control cabinet cabinet, braking cabinet, control panel, in-disk special connection cable, ZONCN recommended custom inverter, the programme

The customer needed a cabinet product consisting of 3 inverters and to achieve its purpose of use Design requirements The protection level of the cabinet is IP20. Cabinet wiring: all secondary voltage lines in the cabinet are BVR-0.75mm2 or 1.0 mm2 multi-stranded copper wire, current transformer lead wires using voltage 750V, 2.5mm2 multi-stranded copper wire.

Customers need to configure a high-voltage frequency converter for air-cooled screw machines, and ZONCN recommends ZCH100 as the high-end frequency converter. ZCH100 series high-voltage frequency converter adopts the form of multi-level “high-high” voltage source of power units in series, i.e., it adopts a number of low-voltage PWM inverter power units in series to connect the high-voltage

Customer requirements   The customer has two sets of 900KW and one set of 1250KW high-voltage inverter, due to the equipment is old, the operation of the frequent failure. Inverter internal power unit failure caused by equipment downtime maintenance time increases year by year, maintenance costs remain high, and some of the internal components of
