● The Computer SDARE-12L PF regulators measure cosφ in supply system and control the connection and disconnection of capacitors to obtain a target programmed value.
● The manual is an easy guide for the use and operation of the Computer SDARE-12L.For manual can be downloaded form the web site of Circutor:www.sdare.net

Any manipulation or use of the equipment out of the conditions specified by the manufacturer may put in risk the user safety. Before any maintenance operation the equipment must be disconnected from power supply. In case of miss operation fault the equipment must be disconnected from supply and remain out of service ensuring against any accidental reconnection. |
1.Regulator Connection
For proper operation it`s necessary to install a current transformer, CT（normally ln /5 A), which primary must be sized according to the maximum expected load current in the installation.
The regulator supply (C-D terminals) must be taken between two phases and the CT should be located in the third phase. See technical characteristics for cable sizes and required protections.
The current transformer, CT, must be located so that it measures the whole load current plus the correction capacitors.

3.Four Quadradrants Operation
The computer SDRK-12L regulators operate in 4 quadrants (suitable for imported or exported active power ). For exported power ,a negative symbol is displayed in the cosφ indication. Check phase connection and setup if there is no exported energy and the indication is not correct (see 4.3,SET-UP-phase)
