SPU2 Surge Protection Unit

The SPU2 Surge Protection Unit is purpose designed to protect Nautel’s solid-state radio transmitters from the transient energy of lightning strikes or ac line distribution faults, without service interruption.

The SPU2 is primarily designed to provide a safe path to ground for currents that result from direct lightning strikes on the transmitting antenna, the surge protection panels also provide protection from common-mode transients originating on the ac line.

Highlights include:

  • Fast response time.
  • Protection device integrity indicators.

Fast Response Time

Suitably rated varistors are located between the ac line and the station reference ground.

Protection Device Integrity Indicators

Neon lamps indicate the integrity of the protection varistors.
