The ALPU-BSU surge suppressor is a high-speed, high-current solid state device designed to protect up to (8) CAT-5 Ethernet/Signal lines and (8) 48 VDC lines. The ALPU-BSU uses only silicon avalanche suppression diodes (SASD). It connects to the service in a pass through configuration. All input and output connections terminate at two “screw type” terminal blocks. All wire harnesses pass into the suppressor housing via waterproof strain reliefs. The aluminum enclosure is also waterproof, and utilizes a neoprene gasket plus a “membrane vent” to release any build-up of pressure and moisture due to cable wicking and enclosure heating.

MECHANICAL/INSTALLATION
Wiring data: The ALPU-BSU is designed to accept up to (16) multi-conductor cables with an outside diameter of up to 0.350”. The enclosure provides an external 1/4-20 bolt to connect the chassis and shield/drain wires to a system GND.
Enclosure dimensions: The suppressor is housed in an aluminum enclosure that is 16” long, 8.5” wide (including strain reliefs) and 2.25” tall.
Mounting data: The enclosure can be mounted to any surface using the two mounting ears on the top and bottom of the enclosure with #8 hardware. Mounting dimensions shown below (not to scale). The device should always be mounted as shown, with the membrane vent oriented towards the ground.
