Power up to 250kVar

The QR models are automatic panels controlled by the digital controller PFR96 and suitable for three-phase 400V 50Hz networks. They are made with capacitors having nominal voltages of 400V, 440V and 500V to meet most demanding network requirements.

The availability of different types of capacitor allows STP frameworks to be installed in networks with harmonic component up to 60% of THDI, non-resonant.

All STP panels are equipped with thermal probe that, once reached the limit operating temperature, allows to disconnect capacitor banks; reset is automatic when temperatures returns within operating range.
