Basler BE1-25 Relays, Single Phase Monitor, Sync-Check, 2 DPDT Contacts, AC/DC Power, Adjst ΔV ΔF ΔΘ

THE BASLER BE1-25 IS A SYNC-CHECK RELAY ENGINEERED FOR SINGLE-PHASE VOLTAGE MONITORING. IT INTEGRATES AN ISOLATED CONTACT SENSING INPUT AND PROVIDES A SYNC-CHECK AUXILIARY OUTPUT DESIGNATED AS 'NO RELAY'. THIS DEVICE TYPICALLY INCORPORATES TWO FORM C (DPDT) OUTPUT CONTACTS, FACILITATING AUTOMATIC PARALLELING OF AC GENERATORS BY EVALUATING VOLTAGE, FREQUENCY, AND PHASE ANGLE DIFFERENCES BETWEEN TWO AC SOURCES. CONFIGURABLE PARAMETERS USUALLY INCLUDE VOLTAGE DIFFERENTIAL (ΔV), FREQUENCY DIFFERENTIAL (ΔF), PHASE ANGLE DIFFERENTIAL (ΔΘ), AND MULTIPLE TIME DELAYS SUCH AS SYNC-CHECK DELAY AND RECLOSE LOCKOUT. THE UNIT REQUIRES AN AUXILIARY AC/DC POWER SUPPLY AND SUPPORTS PANEL OR DIN RAIL MOUNTING.
