DC6006L control library

A python library for controling affordable power supply FNIRSI DC6006L via front usb connector

Power supply link: http://www.fnirsi.cn/productinfo/556155.html

Unfortunately FNIRSI did not share any information on how to work with serial connunication. Library was created by sniffing serial communication with logic analyzer.

!Warning: Firmware for PS is immature. Bug identified so far:

13.04.2021

• incorrect voltage set. for example, you sent 0.7V while power supply could sent 7V or 70 V =) !Please use over-voltage protection when working power supply and usb interface.!

Dependency:

  import serial
  import time
  import serial.tools.list_ports

When you repost or share any information form this page please attach reference to this page

Function list:

.init(com_port) - initialization for power supply

.close() - close serial port.

.set_v_out(voltage) - setting voltage

.set_v_out_retry(voltage) - setting voltage, waiting for replay to confirm, if not retry to set same value

.set_i_out(current) - setting current

.set_i_out_retry(current) - setting current, waiting for replay to confirm, if not retry to set same value

.output_enable()

.output_disable()

.get_status(var_name) - if var_name = none or empty, a list of all variable would be returned. - if var_name = "specific_name" - only specific var value vould be returned

            "v_out": v_out,
            "i_out": i_out,
            "p_out": p_out,
            "temp":  temp,
            "cv_cc": cv_cc,
            "limit_error": limit_error,
            "on_off": on_off,
            "v_set": v_set,
            "i_set": i_set,
            "v_lim": v_lim,
            "i_lim": i_lim,
            "p_lim": p_lim,
            "timeout_en": tout_en,
            "timeout_hh": tout_hh,
            "timeout_mm": tout_mm,
            "timeout_ss": tout_ss

.set_volt_protect(voltage)

.enable_state_reporting()

.get_state() - ret_val = [v_out,i_out,p_out,p1,temp,cv_cc,error,off_on]
