Product description
B503D series frequency control universal vector controller.
Features
Programmable digital input: 4 digital input terminals
Programmable analog input: AI1:0~10V input, AI2:0~10V or 4~20mA input
Open collector output: 1 output
Relay output: 1 output
Analog output: 1 output, 0/4~20mA or 0~10V can be selected respectively
Product advantages
• Frequency setting method: digital setting, analog setting, serial communication setting, multi-speed, PID setting, etc.
• PID control function
• Multi-stage speed control function: 8-stage speed control
• Instantaneous power failure non-stop function
• Speed tracking and restart function: realize smooth start without impact on the rotating motor
• Key function: user-defined multi-function shortcut keys
• Automatic voltage adjustment function: when the grid voltage changes, it can automatically keep the output voltage constant
• Provides as many as 25 fault protection functions: overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload and other protection functions
Product parameters
Input voltage range:380/220V±15%
Input frequency range:47~63Hz
Output voltage range:0~Rated input voltage
