2000W, fully adjustable with SWR/POWER meter and SWR protection

Look here for manuals and updates.

Our new family of digitally controlled FM amplifiers in rack enclosure finally brings the benefits of all-digital control. You can now comfortably set the output power with the UP/DOWN keys and check the SWR, internal temperature or RF output power at any time with a simple glance at the LCD display. SWR and TEMP protection included. Look no further if you’re looking for a reliable amplifier with the comfort and ease of LCD operated digital control system.

Employing the latest RF techniques for an ultra-stable high effeciency design. This unit is supplied with a universal input switched mode power supply and is built into a nice looking 4H 19-inch rack enclosure with big 120mm fans. Unit can be used with any mains voltage system in the world. A built-in heatsink and fan assembly provides cooling to the unit ensuring 24/7 operation. On-board harmonic filtering provides that needed reassurance that your signal is where it should be. Accepts 25W input, but can be modified to other power levels as required.

Why is this DIGITAL FM AMPLIFIER so great?
One might think one of the RF amplifier modules would be enough, but reality is often far from that. Just the basic coaxial cable wiring represents a major problem to many users. Than there’s the issue of SWR protection, which most modules don’t offer, and RF power, SWR and TEMP measurement and display on LCD, which is not just convenient but often helps monitor operation and eliminate the problem fast or even before it happens. Another strong point is the mains power supply, most modules are shipped with PSU that’s just barely able to cope with the load, usually quitting after a couple months, or, as Murhpy would have it, just a few days after warranty expires (in the middle of the top radio show).
A relatively modest additional investment in a better equipment is rewarded by reliable operation, convenience and peace of mind. Here’s a quick summary of the benefits:
- Digital control, you can now adjust output power to a desired value
- Built-in SWR and RF POWER meter
- SWR protection
- No hassle, easy to use
- Mains operated
- Over-dimensioned mains power supply

SWR/Power/Temp meter are not there for the purpose of "measurement", they are there to give relative information about what's going on and to enable basic SWR protection. Do not expect top accuracy in output power or SWR reading; we still recommend SWR/POWER meter for tuning the antenna for example.
