Application of SN300 series

Magnetic Material Pressor(Charging and demagnetizing equipment)


Can be given any current and acceleration/deceleration current time through the panel or communication;

Stable output current, fast response speed, no overshoot.and high qualification rate of magnetic materials;

Low noise and low heat generation Easy installation and easy debugging;

Low coil power consumption and high energy-savingrate;

High reliability, with powerful protection functions: overcurrent overvoltage, overload,over temperature, undervoltage phase loss


Cold Chain Freezer Compressor Unit Technical Characteristics

Support single machine and parallel machine modes:

Support pressure feedback and exhaust temperature collection, with dual feedback of pressure and temperature,ensuring higher energy efficiency of the system while ensuring the target pressure:

Dedicated cold chain compressor control logic.including high pressure alarm, low pressure alarm,high temperature alarm, and low temperature alarm to ensure stable operation of the compressor unit system;

Dedicated valve control logic: pressure relief valve,spray valve, bypass valve:

Superior motor control algorithm, low control current, stable speed, and low noise.

High-protection level VFD SN300-SL

SN300-SL series frequency converter is an IP55 high protection level fully sealed frequency converter,using an IP67 high protection level fan. The entire series uses waterproof PG heads as wire holes,designed for harsh environments,and is resistant to conductive dust,metal shavings, oil stains,etc.Supports asynchronous synchronous motor control, mainly used in high-frequency grinding machines,graphite crucible automatic filling machines, water jet weaving machines,etc.

SN300 E-SL series is applied to the permanent magnet synchronous machines.
