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

The DSL electronic DSY300‑G001 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 10°), ensuring safe synchronization before closing contactors—ideal for industrial setups, standby systems, and grid-tied generator panels.

Key Features:

• Model: DSY300‑G001 (Relay module)  

• Voltage Range: 231 V nominal phase-to-phase, compatible with 400 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 (~7 × 11 × 11 cm)  

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

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