| S/CON/SGDxxxxx/A/14/03/2000 page 1 /3 F/GB RELAIS STATIQUE POUR COURANT CONTINU /DC SOLID STATE RELAY Les relais SGD sont des relais statiques a transistor MOS pour reseaux continus . Cette technologie permet de commuter un courant important avec une chute de tension tres faible (exemple : 0,15VDC sous 10A avec un relais 60A). The SGD ranges includes DC solid state relays using MOS transistor.This technologie allows users to switch an important current with a low drop voltage (example:10A load current gives 0,15VDC with a 60A model) Tension reseau Courant de charge / Line voltage / Load current 10 a/to 32 VDC 30 A 10 a/to 32 VDC 60 A 18 a/to 60 VDC 30 A 18 a/to 60 VDC 60 A 40 4,5 SGD 30 a/to 60A 30 a/to 60VDC Sortie transistor MOS MOS transistor output SGD15100 SGD17100 SGD25100 SGD27100 Commande / Control 3-32 V 3-32 V 3-32 V 3-32 V 3 + +V charge load (*) 4 + out 1 input 3-30Vdc _ 5 1 2 _ 60A + 91 100 82,7 18-60Vdc 4 S S (*) Prevoir une diode de roue libre sur les charges selfiques. celduc France SGD27100 charge +V 3 21 24 3 73 - 5 2 - 0V loads put a / On inductive commutating diode.

La diode de roue libre est obligatoire sur charge selfique . Une transil de protection est integree au relais mais son energie de recuperation est limitee a 1500W pendant 1ms . En cas de longueurs de connexions elevees , prevoir une source de tension ( capacite reversoir sur l'alimentation ) pres du relais . Si les liaisons restent elevees (self de ligne ) une transil exterieure doit etre prevue. Dans tous les cas soigner le cablage pour des liaisons les plus courtes. The load must be connected to + of the power supply. A commutating diode is absolutly necessary with inductive load . The relay includes a transient suppressor but his maximum surge energy capability is 1500W during 1ms . If connection lines are too long, you have to wire a capacitor near the relay on the supply input . You also have to wire an external transient suppressor because of line inductance. In any case you must look after wiring to keep lines as short as possible. celduc r e l a i s www.celduc.com Rue Ampere B.P. 4 42290 SORBIERS - FRANCE E-Mail : celduc-relais@celduc.com Fax +33 (0) 4 77 53 85 51 Service Commercial France Tel. : +33 (0) 4 77 53 90 20 Sales Dept.For Europe Tel. : +33 (0) 4 77 53 90 21 Sales Dept.
