Description
The MOS Low-Side Switch Board is a compact, high-current power control module designed for activating devices such as lights, thrusters, or solenoids in subsea systems. It switches the negative (low) side of the load and accepts logic-level input signals for seamless integration into centralized power architectures with distributed control points.
This board is specifically designed for use with self-locking (latching) switches. It is not compatible with momentary, non-latching, or self-resetting switch types. Compatible Blu-Sub switches include:
– Subsea M10 Rotary On/Off Switch
– Subsea M8 Rotary On/Off Switch
– Subsea M10 Rotary Waveband Switch
– Subsea M10 Pressure Trigger Switch (Conditionally Compatible)
Note: The Pressure Trigger Switch becomes compatible once submerged to its rated trigger depth, where it automatically latches closed. It can be used in shallow water, but manual pressing (momentary activation) is not supported by this board and will not trigger switching.
The board includes a replaceable fuse mounting seat, allowing the protection to be matched to the selected current rating (15A, 30A, or 120A). Its streamlined input structure supports easy integration into custom subsea power control systems.
