Sine Control Adds Lower-Cost PowerClamp

Suitable for transmitter sites, it’s rated at 200,000 surge-amps per phase.

The Dec. 22 issue of Radio World features our Buyer’s Guide for antennas, RF support and power products.

Hank Landsberg is president of Sine Control Technology. The company has a new offering called the HP-200-1-TX.

Radio World: What is the new product?

Hank Landsberg: It’s a lower-cost version of our top-selling, highest-performance surge suppressor. The model number will be HP200-1-TX. It will be suitable for use at transmitter sites, hence the “TX.” It’s rated at 200,000 surge-amps per phase, so it’s ideal for use in high-lightning locales.

RW: How will radio stations use it?

Landsberg: It will be an excellent choice for use with solid-state transmitters that run on 240 volt single-phase power. These are very popular from manufacturers like Nautel and GatesAir, but they are also vulnerable to power supply failure caused by AC power line spikes and surges.

Our existing model HP200-1 has been very effective at eliminating this source of transmitter failure; the new model will make it more affordable without compromising performance.

The HP200-1-TX will be for 120/240 volt single and “split” phase power. It should be installed close to the main electrical panel where the Neutral and Ground wires are tied together.

The unit will also provide a Remote Status Output that can be interfaced to any transmitter remote control system. It will alert the user if there is a power failure or if a fuse in the PowerClamp unit needs to be replaced.

RW: What else should we know? Cost?

Landsberg: Like all PowerClamp surge suppressors, this unit uses a hybrid of multiple suppression circuits to achieve a very low clamping level — just a few volts above the sine wave peak. It’s installed in parallel with the load. There is no voltage loss, nor does its performance degrade over time.

Pricing is not determined yet, but it should be about 25% below the current model with identical performance.
