The PTEK Gamma Series transmitters now reduce your electric bill by 13,667 kilowatt hours and 10.251 tons of CO2 per year. Here’s how:

Assuming your transmitter runs 24/7 or 8,760 hours per year. The OLD 3,000W transmitter was 60% efficient, overall efficiency was 54% (with power supply efficiency). Running 8,760 hours per year it used 48,667 kWh.

The NEW HE Gamma 3,000W transmitter is 83.3% efficient, overall efficiency is 75% (with power supply efficiency) will use 35,000 kWh with an annual savings of 13,667 kWh. These transmitters pay for themselves.

PTEK achieved these significant power savings for the 1,500-10,000 watt Gamma Series by moving from MOSFET devices to significantly more efficient LDMOS based amplifiers. This advance results in an appreciable decrease in overall cost of ownership when purchasing and operating HE Gamma transmitters.

Efficiency of the LDMOS amplifiers not only reduces direct power consumed by converting AC power into RF power; there is also additional cost savings resulting from the lower heat generation of these amplifiers. Less power is lost to generated heat and thus less power is required by HVAC systems to cool the building. With all things considered the combined electric power saving in this new PTEK design is significant.

Further increasing reliability and efficiency is PTEK’s move to the Direct Digital Synthesizer (DDS) based exciters. The new generation PTEK Gamma series exciters use the 1 Giga Samples Per Second (GSPS) DDS which provides low noise and distortion, fast lock up, precise frequency and modulation control and excellent low frequency response.
