Door-clutch DC Isolator Switch Application

ADELS Series DC Isolator Switches are applied to l~20 KW residential or commercial photovoltaic system, placed between photovoltage modules and inverters. Arcing time is less than 8ms, that keeps solar system more safe. To ensure its stability and long service life, our products are made by components with optimum quality. Max voltage is up to 1200V DC. It holds a safe lead among similar products.

 Switching Configurations

 

Dimensions(mm)

 

The  PM2 Series Door-clutch DC Isolator Switch have been specifically designed to switch Direct Current (DC) at voltages up to 1200Volts. Their robust design and ability to switch such voltages, at rated current, mean that they are ideally suited to be used in the switching of Photovoltaic (PV) systems.

The DC switch achieves ultra-rapid switching through a patented ‘Snap Action’ spring driven operating mechanism. When the front actuator is rotated, energy is accumulated in the patented mechanism until a point is reached at which the contacts are fired open or closed. This system will operate the switch under load within 5ms thereby reducing the arcing time to a minimum.

In order to reduce the chances of an arc propagating, the  PM2 Series switch employs rotary contact technology. This is designed to make and break the circuit through a revolving double break contact assembly that wipes as it moves. The wiping action has the added advantage of keeping the contact faces clean thereby reducing the circuit resistance and increasing the life of the switch.
