Digital Display Unit for the Elecraft KPA500


Keith KV5J
 

Keith Ennis (KV5J) is proud to introduce the second in his line of Digital Display Units.  
The Digital Display Unit for Elecraft's KPA500.
 
For the Elecraft KPA500 I have designed a compact, easy to read Digital Display Unit (DDU). It allows the monitoring of five crucial readings all at the same time.
 
1. Power amplifier's heat sink temperature
2. Power amplifier's high voltage supply voltage
3. Power amplifier's current
4. Power amplifier's output power
5. SWR that the KPA500 sees at its output 
 
The DDU measures only 4X4X2 with an easy to read 2 line display that can be located at the operating position and the KPA500 located up to 10 feet away.
 
The DDU is designed with the following features:
 
Easy to read 2 line display
No USB or serial cable to computer
No com port in Windows to manage
No computer needed
Plug and Play
Simply connect the supplied DC power cable to power supply and PC data jumper cable to the KPA500
Retains all functions of the KPA500 front panel
All displayed info obtained directly from the KPA500
 
The DDU will poll the KPA500 and display PA voltage and PA temperature during receive and transmit cycles. It will add watts, SWR and current during transmit. There is a built in hold time to keep the watts and SWR displayed for a short amount of time after unkeying the amp.

The DDU measures is size only 4x4x2 inches with an easy to read 2 line display that can be located at the operating position and the KPA500 can be located over 10 feet away.
 
The DDU is designed with the following features:
 
Easy to read 2 line display
No USB or serial cable to computer
No com port in Windows to manage
No computer needed
Plug and Play
Simply connect the supplied DC power cable to the power supply and the supplied data jumper cable to the KPA500
Retains all functions of the KPA500 front panel
All displayed info obtained directly from the KPA500
 
The DDU will poll the KPA500 and display PA voltage and PA temperature during both receive and transmit cycles.  It will add watts and SWR display for a short amount of time after unkeying the amp.

Thanks for all the orders.  I see I am not the only person that thinks it's important to keep an eye on all the crucial readings when operating the KPA500.
Great way to protect this wonderful investment.
