BASLER BE1-25 SYNC-CHECK-RELAY SOLID-STATE SYNCHRONISM CHECK RELAY T268895

THE BASLER ELECTRIC BE1-25 IS A SOLID-STATE, MICROPROCESSOR-BASED SYNC-CHECK RELAY THAT ENSURES SAFE CIRCUIT BREAKER CLOSURE BY VERIFYING THAT VOLTAGE, FREQUENCY, AND PHASE ANGLE DIFFERENCES BETWEEN TWO POWER SOURCES ARE WITHIN USER-DEFINED LIMITS. IT MONITORS BUS AND LINE VOLTAGES TO PREVENT DAMAGE DURING PARALLELING. IT MEASURES THE ANGLE BETWEEN THESE VOLTAGES AND ENSURES IT IS LESS THAN THE FRONT-PANEL SETTING (ADJUSTABLE FROM 1 TO 99 DEGREES). IT TYPICALLY REQUIRES A SIGNAL FROM THE BREAKER'S 52B AUXILIARY CONTACT TO ENABLE OR TERMINATE ITS CLOSE SIGNAL.
