Ex9QR5 is mainly used for soft start and soft stop of the 3-phase motor,by reducing the starting voltage and current. At the same time, the soft starter also has the basic function for motor protection.It can be applied on fan, water pump, compressor, ball mill, crusher and other loads. • Various protect functions: input phase loss, output phase loss, three-phase unbalance, operation overload, starting current limit timeout, main circuit overvoltage, main circuit undervoltage, load locked/short circuit, too long starting time and too many starting times• 2rd and 3rd motor parameters,which is suitable for the applications of one-tow two, one-tow-three and two-speed motors• Light-load energy saving automatically• Low-speed forward and reverse rotation function by adjusting the thyristor• Function of braking and stopping• Wide input frequency ranges from 35 Hz to 60 Hz• Built-in 485 communication interface and standard Modbus protocol• Easy operability: LCD display, friendly interface and convenient operation Design Serial Number 5 Rated Current 30A Auxiliary Code Bypass Soft Starter Main Power Voltage AC200V- AC690V (-10%~+10%) Control Voltage(Us) AC100V-AC240V(-10%~+10%) Control Frequency 50Hz±2Hz、60Hz±2Hz Class of Pollution Level 3 Rated Insulation Voltage AC 800V Cooling Mode Air Blast Cooling EMC Equipment Level Class A (industrial grade) Level 3 Relay Output Three relay outputs, Bypass relay K1, programmable status relay K2 and programmable fault relay K3 Analog Output Four output types: 4mA~20mA, 0mA~20mA, 2mA~10mA and 0mA~10mA Analog Input One analog input: PTC temperature input Enviornmental Temperature Working at: -10°C to +40°C (+40°C and +50°C should be derated,and the current derated every 1°C increase 2%) Dimension (mm) 145x268x190 Certifications CCC, CE, UL listed
