CRE Technology – C2S A25Z0 – 100 V Auto Synchronizer & Safety Column, DIN‑92

The CRE Technology C2S A25Z0 is a microprocessor-based synchronizer and safety column designed to aid in manual generator-to-bus paralleling. It features an integrated synchronoscope display, dual bar-graphs for frequency and voltage variance, and a safety relay to ensure coupling only under safe conditions. Fully powered from the 100 V source (85–115% rated), it mounts neatly in a 92 mm DIN panel with an IP65-rated front.
