Heat sink and Fan

Cooling components to keep your transmitter's final amplifier alive — genuine Delta DC cooling fans and the power modules that drive them. Every watt of RF your transmitter makes becomes heat; moving that heat out is the difference between a transmitter that lasts decades and one that fails in a season.

• Delta FFB0848SHE — 48 V / 0.24 A, 4-wire (PWM-capable) DC cooling fan, the original part used in Elecsky transmitter chassis
• 12 V / 1.35 A cooling fan — high-airflow drop-in replacement for smaller amplifier pallets and power supplies
• DC-DC power module — wide input 12–50 V down to 12 V / 2 A output, lets you run a 12 V fan from 48 V or 50 V transmitter rails
• Four-wire fans report speed for fan-failure monitoring in unattended transmitter sites

Fans are the most-replaced part in any transmitter — keep spares on the shelf. If your transmitter runs hot or a fan has gone noisy, replace it before the thermal protection cycles your station off air. Not sure which fan fits your chassis?
