- Page 2 This compact and lightweight amplifier employ the new generation of NXP™ extremely rugged 50V RF power LDMOS MOSFETs. The built-in decoder, which allow you to forget about the band setting, and the electronic solutions adopted, give this amplifier the most complete and very easy to operate in the market.
- Page 3 PLUS HVLA1K3 USERS MANUAL Don’t turn ON the amplifier before connected the ANTENNA; a hazardous RF voltage may be present on the antenna connector with no antenna connected. Don’t disconnect an antenna during transmission; fire or electric shock may be possible. Don’t expose the amplifier to rain, snow or any other liquids;...
- Page 4 PLUS HVLA1K3 USERS MANUAL Don’t obstruct the entries for cooling present in the cover of the amplifier; the poor heat dissipation generated, in this situation, may damage the amplifier. Don’t place the amplifier near walls or other obstacles; the poor heat dissipation generated, in this situation, may damage the amplifier.

Page 8: Preliminary Precautions
PLUS HVLA1K3 USERS MANUAL PRELIMINARY PRECAUTIONS Before you start to install the amplifier, fully read this manual. Carefully remove the amplifier from its boxes and packaging materials and inspect for physical damage incurred during shipping. If any damage is found contact immediately your supplier. Keep the original boxes and packaging materials;... - Page 9 PLUS HVLA1K3 USERS MANUAL CONNECTION AND OPERATION with KENWOOD™ transceiver 6.1 Connect AC power cord and coax cables as mentioned on page 9. Run a shielded cable from the transceiver “REMOTE” connector to the amplifier rear panel “RELAY” phono (RCA) female connector.
- Page 10 PLUS HVLA1K3 USERS MANUAL 6.10 IMPORTANT NOTES: For high duty cycle transmissions like RTTY, it is advised that you use the intermediate output power position (green LED “LOW” lit up). Due to the relatively low switching time of the TX-RX relays, we don’t guarantee the use of the transmission high-speed CW Full Break-in mode for speed more than 25-30 wpm.

Page 17: Protection Circuits
PLUS HVLA1K3 USERS MANUAL 13 PROTECTION CIRCUITS There are many protection functions in this amplifier. If the amplifier has shut-down for some reasons, before re-setting, correct the possible cause of the shut-down. Turn OFF the main AC power switch once and back ON to reset. If the amplifier is operated in such a manner that multiple protections work repeatedly over a long period of time, the amplifier can be seriously damaged. - Page 18 PLUS HVLA1K3 USERS MANUAL 13.5 Power Supply Unit (PSU) protections The internal switching power supply unit features the following automatic protections: - Soft start - Short circuit - Over current - Over voltage - Over temperature A built-in green LED check its normal activity. If the green LED is OFF means that the PSU is in an auto-protect condition, or AC mains power supply fuses are blown.
