The Basler Electric PRS 250 Veri-Sync Relay is a solid-state synchronizing relay designed to supervise the conditions required before connecting a generator to an energized bus. It continuously compares the voltage, frequency/slip and phase angle of two AC signals and operates its built-in output relay when the synchronization conditions fall within the specified limits.
Key Features
- Monitors generator-to-bus synchronization
- Compares voltage, frequency and phase angle
- Adjustable 0°–20° phase-angle setting
- Maximum ±0.5 Hz slip-rate supervision
- Built-in power switching relay
- SPDT output contact
- Solid-state electronic construction
- Designed to withstand vibration and shock
- Wide −40°C to +70°C operating range
- Suitable for generator paralleling systems
- Requires no periodic internal maintenance under normal service conditions
Typical Applications
- Marine generator synchronization
- Shipboard generator paralleling
- Diesel generator sets
- Generator switchboards
- Main and emergency switchboards
- Industrial power-generation systems
- Multiple-generator installations
- Generator-to-bus synchronization
- Power plants
- Legacy generator control and synchronization panels
