The CRE Technology AZ‑CS is a compact, DIN-sized auto-synchronizer and safety column, ideal for paralleling generators to utility or busbar power. It supplies its own power from the input source and integrates a complete synchroscope, frequency and voltage bargraphs, plus a safety relay to ensure precise and secure synchronization. Designed for  VAC systems, it’s CE-compliant and built for rugged industrial use.

Key Features:

• Model: AZ‑CS ( VAC input)

• Synchronization Display:

– Phase: -LED circular synchroscope (< . Hz)

– Frequency Δ: -LED bar for ± Hz (expanded ± Hz range)

– Voltage Δ: -LED bar for ±% variance

• Safety Relay:  A contact switches when Δ f < . Hz, phase angle ±°‑°, & ΔV ±.‑%

• Power Supply: Draws from generator and bus voltages (no external DC)

• Supply Requirement:  VAC (other versions exist for / VAC)

• Environment & Dimensions: IP front, - to + °C, weighs ~. kg, size ×× mm mounted via screws at × mm
