Product Features
Used as constant voltage source, constant current source, switch test power supply.
1.When used as a regulated power supply, the regulated voltage value can be preset at
any value from 0 to 300 VDC, adjustable throughout, and the precision of the regulated voltage is high.
2. When used as a constant current power supply, the constant current value can be arbitrarily
preset from 0 to 10 ADC and can be adjusted throughout. It can be used as a small charger to
charge the battery pack at a constant current.
3.It can be used for automatic test of switch (circuit breaker) operating voltage value.
4. Can be used for switch (circuit breaker) action time.
5. Precise continuously adjustable output, the whole regulation voltage value and constant current
value can be adjusted arbitrarily.
6. Strong anti-shock load capacity, the maximum instantaneous working current can reach 30A.
7. Built-in high-precision digital voltmeter current and voltage display, easy to use.
8. Built-in digital millisecond meter, LCD display millisecond meter data.
9. Using PWM technology, small size, light weight, low loss, short circuit self-protection.
10. With output on and off functions, the output can be turned on after presetting the regulated
voltage or constant current
11. It has over-current, over-voltage, short-circuit, overload, over-heat protection, high reliability.
12. Fully isolated design, highly safe.
13. The 32-bit ARM processor with high-performance Cortex-M3 core has fast data processing
speed and high precision.
14. Integrated two functions of universal adjustable power supply and intelligent millisecond meter,
high performance over cost ratio.
15. The rotary encoding switch is used to adjust the output voltage, which is safe and reliable.
16. When used as a constant current power supply, the constant current value can be preset from 0 to 10A.
17. Strong anti-shock load capacity, the maximum instantaneous working current can reach 30A.
18. When used as a constant current power supply, it can be used as a small battery pack
charger for constant current charging.
19. Comes with a high-precision digital voltmeter, easy to use.
20. Using 16-bit PWM technology, small size, light weight, low loss, short circuit self-protectio
21. With output on and off functions, preset constant current to turn on output.
