Technical FAQs 4
What are AC contactors used for?
AC contactors have a crucial role in electrical circuit systems. It helps in the effective control and management of electricity flow across various high-current demanding loads. It is widely used in operating HVAC, compressors, heavy-duty motors, and similar others.
How to choose an AC contactor?
Make sure the AC contactor holds credible certifications. CE and UL are some important certifications to consider. You can find such information on the manufacturer’s product page. AC contactors are necessary control systems to regulate the flow of electricity in heavy electrical loads.
Should a parallel inverter/charger be identical?
In a parallel system, each inverter/charger should be identical. Hovever, this is not always the case. Each inverter/charger contains an internal AC input contactor. These contactors are not always completely identical, they can have a small difference in their internal resistance, compared to the other contactors.
What happens if an inverter/charger has a small resistance difference?
Each inverter/charger contains an internal AC input contactor. These contactors are not always completely identical, they can have a small difference in their internal resistance, compared to the other contactors. This small resistance difference might result in the AC current being diverted from one unit to another.
