OM-Power Shortwave Amplifier

OM-Power was founded in 2004 by two Slovak Radio Amateurs. Very quickly, OM-Power has developed a successful business in the manufacture of amplifiers. The power amplifiers are employed on every continent and in almost every country in the world with enthusiasm.

OM2000+ Shortwave-PA, 2000W

 

OM2000+ Amplifier OM2000+
OM2000+ Amplifier Rear view

The OM-Power Amplifier OM2000+ works from 1,8 - 29 MHz, including the WARC bands. The Amplifier works also on 50 MHz. A FU-728F ceramic tetrode ensures a stable output power up to 2000W.

The OM2000+ has 3 antenna outputs, which can easily be switched from the front panel. The operating parameters are displayed on a OLED display with 4x20 characters. In addition, a analog cross needle meter for the forward power and reflected power is installed.

In addition, several LEDs indicate the operating status at a glance. For a simple adjustment to the operating frequency, there is a TUNE-Indicator, which indicates the correct tuning.

Extensive protective circuits prevent damage to the OM2000+ event of incorrect operation. Critical parameters such as SWR too high, too high a grid or anode current, mismatch, etc. are constantly monitored. If an error occurs, the PA switches to standby.

A temperature-controlled fan ensures the sufficient cooling of the FU-728F tetrode. If the tube should be changed, the voltage will calibrate automatically. A complicated trimming is not necessary.

The OM2000+ is in this class with only 24kg, the lightest tube amp from commercial production. In addition, the OM2000+ works on 6m with full power.

OM2500A Amplifier
OM2500A
OM2500HF Amplifier
OM2500HF
The Amplifier OM2500A has with the installed GU84B tube a output power up to 2500W.
The special feature of this amplifier is the automatic mode. The OM2500A tunes alone to the right settings and is immediately ready for use. Of course, this amplifier can be adjusted manually.
Optionally available is a remote control unit, which allows the amplifier can be operated remotely.
Besides the automatic version is available with the OM2500HF a version with only manual tuning.
On the front panel, a band selector switch has come as an additional control element and the display is dropped off. This means for an operator handle more but for a better price.

Both amplifiers are connected with 2 power lines. Usually you need 2 different phases. When a phase is appropriately protected, both lines can be connected to one phase.

Through several bar graphs the output power and the reflected power is also displayed during the transmission. Additionally, you can read the voltages. At the same time, the display also serves as a tuning aid.

OM4000HF Shortwave amplifier, 4000W

The amplifier OM4000HF provides two FU-728F tetrodes with a maximum output of 4000W on all HF bands.

With such a high output power, high demands on the cable and the antenna are provided. However, should something go wrong, the amplifier can support up to 350W reflected power and then goes to stand by. Various other protection circuits ensure that the OM4000HF is not damaged on any errors.

As usual with the OM-Power amplifiers in this power class, 2 phases of the power supply are also needed here. With high enough fused phase you can use both lines on one phase.

OM4000A Controller
For the OM2500A a remote control unit is available, which allows remote operation up to 10m. Additionally, the use of a LAN network allows operation over longer distances. Also, the control via the Internet is possible. With the remote control unit the OM4000A can be operated remotely up to 10m. For longer distances there is a LAN connection available, which allows to integrate the controller into a network or even to control over the Internet.

All operating states are indicated by LEDs on the remote controller. A 30-digit bar graph display shows the actual output power TX-mode.

Remote unit is interfaced to LAN via XPORT made by Lantronix. In the controller a web interface is implemented where the settings can be changed differently from the default values. For remote control and monitoring of pthe amplifier you need a special software, which is provided free of charge.

The remote controller must be properly grounded!
Connect the screw on the back of the box by a copper cable (at least 4 mm2 cross-section) with the station ground. Connect your transceiver and the amplifier on the same ground! If you use an amplifier with high output, you need to be aware that your system must be properly grounded. All parts must be grounded on the same system. Use short cable, and make sure they have good contact!
