Installation signal lamps Ex9PDe are designed and tested according to standard IEC/EN 60947-5-1. They are based on LED technology and suitable e.g. for circuit status indication.
There are available versions with rated operating voltage 24, 48 and 230 V AC/DC, with one or two dual-colour (green/red) LEDs. The last variant with three red LEDs is available with operating voltage 230/400 V AC. This kind of signal lamp is used mainly for phase voltage presence check in 3-phase connections.
All versions are designed as 1 module unit width devices including the three LED version. Used internal technology of LED lights ensures very low power consumption during operations and very high lifetime.
