DSL electronic – DSY300-G001 – Synchronizing Relay 231/400 V

The DSL electronic DSY‑G is a robust synchronizing and frequency control relay used to automatically manage the connection of backup generators to power networks. It monitors voltage, frequency, and phase angle (up to °), ensuring safe synchronization before closing contactors—ideal for industrial setups, standby systems, and grid-tied generator panels.

Key Features:

• Model: DSY‑G (Relay module)  

• Voltage Range:  V nominal phase-to-phase, compatible with  V systems ()

• Function: Monitors grid and generator for synchronization and phase alignment; trips or holds contactor if out of sync  

• Performance: Detects frequency and voltage mismatches; auto-synchronizes when criteria met  

• Mounting: DIN-rail housing, compact design (~ ×  ×  cm)  

• Status: Often available reconditioned/used, tested; supported with datasheet from DSL electronic  

• Ideal for: Diesel generator synchronization, standby power transfer, microgrid sequence control
