Eltek Flatpack2 HE 48V/2000W is an ideal power supply for 1 kW class amateur radio Solid State Power Amplifier projects.
This 3.5″ touchscreen-based controller allows setting and monitoring of parameters that Flatpack2 provides via it’s CAN-bus:
• AC Volts in
• DC Volts out
• Load current
• Intake temperature
• Output temperature
• Operating status
• Alarm & warning messages
Current (as in ‘now’) voltage can be shifted up or down in 200mV steps by touching the UP/DOWN arrows.
This does not affect the default start up voltage.
Log in icon indicates when controller sends a log in request. Every 5 seconds.
Short press “SET” button: reset screen saver
Long press “SET” button: enter Set menu
The following can be configured on the Screen Settings page:
• Screen brightness
• Screen saver (enter 0 to disable screen saver)
• Output voltage to 1 or 2 decimal places
The following can be configured on the General Settings page:
• Current Limit in deciAmps
• Short or long ‘walk-in’.
Set Default Volts page.
Voltage is entered as decivolts by keypad.
ie: 48.00 V = 4800
If an alarm or warning (or both) state is detected, the appropriate icons become red.
Clicking on either of these icons will take you to the Warnings/Alarms page:
Foreground and background colours of each parameter can be adjusted to your own preference, as well as a choice of two fonts.
Example: setting DC Volts colour & font:
+5V power supply uses a Maxim MAX5035 DC-DC Step-down converter. The MAX5035 is rated to an input voltage of 76 volts.
Quality Panasonic aluminium electrolytic capacitors are used. Capacitor on the DC input is rated at 100V.
A diode on the DC input provides against accidental reverse polarity connection.
The controller easily mounts to the Flatpack chassis, or any other flat surface, using adhesive PCB stand-offs (supplied).
