Front  view of the PowerMaster I+ Display

PowerMaster I+ - Display only (no coupler) - will work with 3 kW HF-6m couplers. includes RS232 cable, Power supply, 12 V DC cable if you want to use your shack supply.  This one has the high end OLED display used in the PowerMaster II.

Some of the many features

• ALC-1 - ALC protection option, shuts down your transmitter fast but yet allows ALC normal operation    
• FASTEST Bar graph on the Market, makes tuning an amp or a tuner a joy, faster than an analog meter. So fast it can catch the first "dit" at 99 WPM and even show you if your rig has a RF spike problem.  Why mess around with other meters that have have had display failures?
• Displays VSWR, Power, and Bar graph at the same time.
• Runs with or without a PC connected to it. That means there are no programming hassles and issues setting this meter up. 
• Works right out of the box.
• Accuracy is typically better than +/- 3% over frequency and temperature ranges    
• Peak Hold Modes – programmable for fast(1/2 sec), medium, slow, and Long ( 5 sec) for CW, SSB, data, FM, whatever you're sending!    
• Separate Display and Coupler/Sensor boxes–  Sensor can be remotely located at your amp or in your mobile unit this also keeps the high power cables away from your radios, audio equipment, PCs etc.  No nasty RF cables on top of your desk or radio to cause RFI and other clutter issues! The coupler is using DC only, no RF is sent to the meter. A good thing!
• Remote use, even 100 feet of cable between sensor and display has no drop in power measurement. 
• Multiple couplers on one display using a Y ¼” TRS adapter
• VSWR Alarm – programmable trip point, LED and Relay – Can shut down your amp fast  
• Power Alarm -  programmable trip point, LED and Relay - Alerts you that your amp has tripped out
• Alarms can maintain until manually reset, or you can program an auto alarm reset
• Bar Graph – Operates in two modes, Auto Ranging Power and VSWR you can peak your amp sending dots or talking into a mic, or dip your VSWR with your tuner using dots. Easy on the tubes and efficient.
• Bar Graph in Power mode – Auto Ranging in user selectable ranges – Easy to read  
• Large LCD Display – Easy to read even in bright sunlight - low energy consumtion
• Programmable from front panel or via USB or RS232 – Even display your call letters in it too!
• Free Application for your PC - Will allow remote user’s full use of meter even on the internet  
• All Metal Boxes – Rack Mount Options available, 1 or 2 units in a 19” 2U panel
• Coupler uses SO239 RF connectors
• Display Head Size 7” X 3-3/4" Face, 4-1/2” Deep
• Interface to any RS232 Port
