Müller SC 38.20 pro5 Digital Time Switch, DIN Rail, 110-230 V AC, 600 W LED, 1 Channel, 50 Programs 24783

Program up to 50 switching steps with 1-minute precision on this DIN-rail digital time switch. The SC 38.20 pro5 handles 600 W of LED load while the potential-free changeover contact supports 16 A resistive and 10 A inductive at 250 V AC. An 8-year lithium power reserve keeps the schedule running through outages, and automatic daylight saving plus a holiday program reduce manual corrections.

Overview

The Müller SC 38.20 pro5 is a single-channel digital time switch for DIN-rail mounting. It operates on 110–230 V AC (50/60 Hz) and provides one potential-free SPDT contact.
