Description

Designed to control one Eltek Flatpack2 HE 48V/2000W rectifier.

Using a 3.5″ touchscreen this 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
• and any alarm/warning messages it generates

Main screen:

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

 

Set Menu:

 

The following can be configured on the General Settings page:

• Screen brightness

• Screen saver (enter 0 to disable screen saver)

• Output voltage to 1 or 2 decimal places

• 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).

 

What’s in the box?

• 1 x Controller board is fully assembled with CAN bus adapter, Arduino Nano, programmed and tested

• 1 x Nextion 3.5″ Enhanced HMI touchscreen, programmed and tested

• 1 x matching 2 pin polarised connector for PCB power

• 1 x matching 3 pin polarised connector for CAN data

• 4 x adhesive PCB stand-offs

 

This is ready to connect to your own Flatpack2 and breakout board.

Designed to control one Eltek Flatpack2 HE 48V/2000W rectifier.
If you want to control more than one Flatpack2, you will need to supply your own Arduino Nano firmware.
