The transmitter-powered heat sink is compatible with most Quasonix transmitter models and includes a power supply for North American operation. The transmitter-powered heat sink eliminates the need for an external power supply. With an integral fan, power supply, and temperature-controlled power on, the provided connectors and pigtail cable allow the heat sink to draw power directly from a Quasonix transmitter. A fan-cooled copper heat sink is also available. Contact Quasonix for heat sink recommendations for your TIMTER transmitter.
