  • peculiarity/
  • function/
  • parameter
  •        Multiple functions design based on PS-16, it can be used as constant voltage source, constant current source and switch testing power supply.
           When using as stabilized voltage supply, the stabilized voltage value can be randomly set between 0~300VDC. Fully adjustable, high stabilized voltage precision.
       When using as constant current power supply, the constant current value can be randomly set between 0~10ADC. Fully adjustable, it can get constant current charge to storage battery as small sized charger.
       Can automatically test the operating voltage value of switch (disconnector).
       Can test the actuation time and operating period of switch (disconnector)(built-in three-channel digital millisecond counter).
           With precise, continuous and adjustable output, the stabilized voltage value and constant current value can be adjusted randomly.

    ■  Strong ability for surge suppression and load, the maximum instantaneous working current can get 30A.
    ■ Built-in digital voltmeter with high precision, easy to use.
    ■ Built-in three channel and multilevel digital millisecond counter, the LCD can display the millisecond countering data.
    ■ Adopting PWM technology, it has small volume, light weight, low consumption and self-protection with short circuit.
    ■  Equipped with output on/off function, it can start the output after presetting stabilized voltage or constant current.
    ■ Equipped with complete overcurrent, overvoltage, short circuit, overload and overheating protection, it has high reliability.
    ■  Full-isolated design, high security.
    ■  
    As for a human-computer interface, the LCD display in size of 128X64 is all displayed in Chinese. It’s informative and easy to use.
     
     
     
     
    ■  Adopting 32-bit ARM processor with high performance Cortex-M3 core, it has the features of high processing speed and precision.
    ■ Combined with general adjustable power supply and three-channel intelligent millisecond meter these two functions, it has high cost performance.
    ■ Adopting rotary coding switch to adjust output voltage, it’s of high security.
    ■ When using as constant current power supply, the constant current value can preset between 0~10A.
    ■ Strong ability for surge suppression and load, the maximum instantaneous working current can get 30A.
    ■ When using as constant current power supply, it can get constant current charge to storage battery as small sized charger.
    ■ Self-prepared digital voltmeter with high precision, it’s easy to use.
    ■ Adopting 16-bit PWM technology, it has small volume, light weight, low consumption and self-protection with short circuit.
    ■  Equipped with output on/off function, it can preset constant current and start the output.
    ■ With single wiring for tripping and closing, it decrease the wiring times.
    ■ Equipped with complete overcurrent, overvoltage, overload and overheating protection, it has high reliability.
    ■  The millisecond meter can both start with supply voltage, or with the external switching value.
    ■ It can simultaneously measure the three routes of external switching value’s on-off time and state.
    ■ Every single switching value can all keep 99 groups timing data.
    ■ Full-isolated design, high security.
