Current and voltage sensing contactors
July 2017
Electrical Power & Protection
Gigavac has released a new range of current and voltage sensing contactors. These can help reduce the number of components in monitoring and control systems by integrating the sensing controls within the actual contactors. The range includes:
• 350 A and 600 A contactors with over-current sensing and automatic trip function. Trip current is settable via an external programming resistor.
• 350 A and 600 A contactors with current sensing outputs. Current is proportional to voltage output of 0-5 or 0-10 V.
• 350 A and 600 A contactors with low voltage disconnect and auto-disconnect function, optimised for vehicles with dual battery 12 V/24 V systems.
The Gigavac Epic extended performance impervious ceramic (EPIC) sealed AC/DC contactors can be used in harsh environments, under water and at temperatures from -55 to 85°C, and can be mounted in any position. Also called a relay or solenoid, they are the preferred contactor for heavy trucks and equipment, buses, emergency vehicles, electric vehicles, hybrid vehicles, boats, light rail, mining, oil refineries, construction equipment, military vehicles, power management systems for battery charging, fuel cells, battery backup, solar, wind and wave power systems and factory automation where long life and high reliability are needed.
