SPD-21G Wiring diagram





Product Description:

The Model SPD-21GDCB, CEI/Premisa 2-way equal loss horizontal ported output RF splitter & provides an excellent RF signal path for analog and digital cable TV and off-air signals. While providing a non-compromising DC path for coaxial powering devices.

Applications of this splitter range from remote security camera powering, drop or subscriber amplifier powering to VoIP ring voltage applications.

Product Standard Features:

Patent pending new design, DC overlay circuit removes ALL DC from RF ferrites. New design provides DC path with capacity of 300ma @ 18vdc with no impact on intermodulation specifications.

Design allows co-existances of drop amplifier and cable modem on same coaxial cable.

Patent pending gold plated 360o insert pins

Tin-plated, zinc die-cast housing with soldered back plate provides -130dB of RFI. All are
highly precision machined with SCTE compliant threading and are spaced on 1" centers.

All ports are water sealed and have be tested to withstand 30 psi of internal pressure. All ports comply to all existing SCTE standards.

Built-in NPO capacitors on all ports. All components are temperature hardened. Devices designed to remain stable in enviroments of -40 to +85o C and maintain all technical specifications.

OUTPUT PORTS SURGE - Pass 6kV 200A @ 100khz ring wave surge test. As defined in IEEE C62.41.1991 for cat A3 type device.

INPUT PORT SURGE - Pass 6kV 3kA combination wave @ 100khz ring wave surge test. As defined in IEEE C62.41.1991 for cat B3 type device.

Special magnetism resistant ferrite core material allows ferrites continued operation within designed specifications when high RF levels are applied.

NESC Compliant 4.55mm ground clamp, stainless steel wood mounting screws and UV protected labels.

Specifications subject to change without notice.
