Product Performance
Versatile features: It has a multifunctional precision LED synchronous meter function, which can perform voltage measurement, frequency matching, phase angle comparison, voltage regulation, circuit breaker time compensation, etc.
Easy programming: All setpoints can be easily programmed through buttons.
High safety: It has high user safety and can protect users from dangerous voltage effects during setpoint programming.
Strong anti-interference ability: has high immunity to harmonic distortion.
Dead zone function: It has a dead zone function. When the bus voltage is lower than the preset dead zone bus level and the generator voltage exceeds 80% of the nominal value, the LED (SYNC) will light up. After the grid voltage is restored, CSQ-3 will remain in the dead zone function for 5 seconds.
