ESU-D2/UC110-240V
Das Erdschluss-Überwachungsgerät ESU-D2x überwacht den Isolationswiderstand von Gleichspannungsnetzen gegenüber Erde. Folgende Eigenschaften hat das Gerät:2 Alarmlevel - einmal einstellbar 4-30 kOhm (AL1) und einmal fest 4 kOhm (AL2)Optischer Isolationsindikator mit 6 LedsDie Trendanzeige mit 2 Leds informiert den Anwender darüber, welcher Pol des zu überwachenden Netzes einen geringeren Widerstand zur Erde aufweist.Erdunterbruch ÜberwachungAusgänge: 1x Umschaltkontakt für AL1 (Voralarm); 1x Schliesskontakt und 1x Umschaltkontakt für AL2 (Hauptalarm), 1x Analog-Spannungsausgang, welcher den Widerstandswert repräsentiert (0-50kOhm <-> 0-5V).Umfangreiche Selbsttestfunktionen und ein stabiler Aufbau ermöglichen einen zuverlässigen Einsatz auch unter schwierigen Bedingungen.
