SVC OUTPUTS COMMUNICATIONS
SVC stands for “Static Var Compensation”. • Modbus RTU RS-485, 2400-115200 baud
The unit has 3 SVC outputs which are duty cycle • TCP/IP client
controlled PWMs that control 3 reactors with a • SMTP
precision of 1000 steps. • GSM-SMS sending
• e-mail sending
Thus the controller is able to supply almost any • Central Monitoring through IP
required reactive power on each phase, enabling • Free configuration & monitoring software
matching the exact required PF, independently from
capacitor bank selection.
