Stellar SR22-09 Soft Starter

Stellar SR22-09 Compact Soft Starter manages reduced‑voltage starting for 3‑phase motors by using thyristors to ramp current, then switching to an internal bypass for efficient running. It is a 9 A full‑load amperage unit that accepts 110–120 VAC, 208–230/240 VAC, or 440–480 VAC input (50/60 Hz) and provides matching output voltages, with 1‑ or 3‑phase input and two controlled output phases (out of three) via an SCR output. Housed in a 45 mm frame for DIN‑rail mounting and rated IP20, the device supports 10 starts per hour and a 0–60 Hz output frequency range, with trip classes of 2/10/20/30. This SR22‑09 belongs to Stellar’s SR22 family, designed for compact motor control where inrush current must be managed and space is at a premium.
