Description
The SUBSEA-SW3-CRE subsea power switch is ideal for controlling power on a subsea sled, or small-scale subsea operating system. The square mounting plate is made of 316 stainless steel, with a rotating switch bar containing two permanent magnets. Upon rotation to the horizontal “ON” position, one of the two magnets align with a reed switch sensor housed in a stainless steel enclosure behind the mounting plate, activating a solid state relay. The relay is suitable for switching 24vDC up to 500mA. This can feed the power through the switch on low powered systems, or it can be used to active a larger relay in the main system that controls the power for higher voltage and current.
The stainless steel housing incorporates one Subsea bulkhead connectors. The SUBSEA-SW3-CRE is provided with a 5m cable, equipped with CRE 3-pin Subsea connectors. The entire switch assembly and connectors are rated for operation in seawater depths up to 4000 meters.
This switch is primarily designed as being used as an external power supply switch with one cable connection to the main subsea system that can be operated by an ROV.
