(3) Voltage signal for remote sensing: if you need remote sensing, connect the sensing wire from the positive end of your load to this connector. (4) Ground terminal. (5) Connector for I/O pins: these pins are directly connected to some of the I/O pins of the Arduino Micro board. See 5-2 for more details.

  • Page 10 Warning: Do not connect any load to the power supply before it's turned on. Likewise, make sure to disconnect the load before shutting down the power supply. Damages to the power supply can happen if you do not follow this. Such damages are not under warranty. Warning: If you are running an inductive load like magnetic coils, DC motors, stepper motors, etc., make sure to connect your load with the output set to zero and change the voltage/current slowly, and NEVER turn the power supply on or off with a inductive load connected!

    5) The power supply reserved 6 memory positions for voltage, current and OV levels. Use “SAVE” key to store the current settings to one of the 6 memory locations, and you can use “RECL” key to recall one of the stored settings. 3-3 Constant Voltage / Constant Current Characteristics The power supply is a regulated constant current / constant voltage (CC CV) power supply, and is characterized by automatic crossover from constant current (CC) to constant voltage (CV), or vise versa, depending on the load...

  • Page 15: Fuse Replacement

    Warning: The following instructions are to be performed by qualified personnel only. To avoid electrical shock, do not perform any servicing other than the contained in the operation instructions unless you are qualified to do so. For further questions, please contact factory support at support@volteq.com. 4-1 Fuse Replacement If the fuse is blown, the power supply will not turn on.
  • Page 16: Line Voltage Conversion

    Warning: For continued fire protection, replace fuse only with 250V fuse of the specified type and rating. A replacement fuse must be slow blowing type. 4.2 Line Voltage Conversion The power supply will work with line voltage of 110AC or 220V AC. Change from one line voltage to another is done by changing the selection switch in the back.
  • Page 17: Reverse Voltage Protection

    To reset the power supply that's in the OV protected state, follow the procedures below: 1) Disconnect the load. 2) Set OV level to be higher than the voltage limit, typically by more than 0.5V. 3) Press on the button labeled as “OV Reset” in the back. The OV light should be off now. 4-4 Recovery from Over-temperature Protection If the internal temperature is too high, the power supply is disabled due to over-heating.
  • Page 18: Software Capabilities

    Arduino is a very popular hardware platform for embedded intelligent devices. The hardware platform is very stable and versatile, and there are a lot of programs available for download. The Volteq EP models come with built-in Arduino Micro board to control and read the output. It is not our intention to provide fully packaged software, but rather to provide a very versatile hardware platform and starter software package so you can have full access to the power supply capabilities, and build rich application capabilities to suit your needs.
  • Page 19 Active feedback loop to stabilize voltage / current: this is automatically enabled; with active feedback control, output is much more stable than the analog version (EX models), and typical ripple noise is less than 5mV and 5mA for most models.
