RF Concepts, LLC Alpha 9500 Linear Amplifier User Manual

Product Release 1 Preparing Your Station

Use new, clean connectors and install them according to manufacturer

recommendations. Clean the connectors after soldering them and before

mating them with the amplifier.

Install system feedlines following good engineering practice and

according to manufacture recommendations.

NOTE: The FCC requires users to check their installations for

compliance with published values for allowable exposure to RF fields.

This information is available in ARRL publications, FCC printed rules,

and on the web. We strongly recommend that you do this for any

installation, both fixed and at an expedition or contest site.

If you have any questions regarding engineering your amplifier into

your amateur radio station, go to www.rfconcepts.com and click

Support.

Step 5 Provide surge protection.

Induced energy from nearby electrical storms or other power transients

may damage components. Such damage is not covered under warranty. It

is therefore important to use a good lightning arrestor. However the only

lightning-proof solution available is to disconnect antenna feedlines and

AC power when the equipment is not in use.

NOTE: Whenever the amplifier is online — either off, in standby

(STBY), or in warm-up with the WAIT LED lighted — the amplifier is

bypassed and the exciter is connected directly to the antenna. The

throughput limit in all cases is 1500 W.

3.2 Limitations of Operation at 90–130 VAC

Electrical-power equipment draws twice as much primary current from

120 V mains as from 240-V mains. Therefore, if you operate the Alpha

9500 on typical 120 V/20 A household circuit without exceeding the 20-

A circuit rating, you limit maximum peak power output to about

600–1000 W.
