Features:
--High-precision LED 4-digits digital display, intuitive.
--Constant Voltage (CV ) & Constant Current (CC ) Function.
--8cm intelligent fan, excellent heat dissipation effect, effectively extend the life of the fan, reduce noise.
--Plastic panel, more beautiful, voltage, current setting coarse and fine knob, make setting more accurate.
--Using advanced technology, effectively reduce the weight of power supply, convenient power supply movement.
--This DC power supply can provide electronic devices of direct voltage from 0 to 30V and current from 0 to 10A. --Input voltage is switchable(AC110V/AC220V) through the switch on the back of the instrument.
--Multiple protection functions, current limiting protection (OCP), over temperature protection (OTP), over power protection (OPP). --Energy-saving and efficiency: over 80% power, 40% higher than other liner power supplies.
--Suitable for electron fans, research people and the professional people.
--It can be widely used in production line test, electrical maintenance, aging products, battery charging, laboratories, scientific research and teaching and many other areas. Note: Before use, you need to adjust the switch on the back of the power supply to the correct voltage and then use it.
It was fault product.
Output voltage is 32V at 0A, but supply current only 1.6A, output voltage became down to 24V.
Open the case then I found two resistor (330Ω5W). Another one product(OK product) have three resistor (330Ω5W).
I put on resistor, but I cannot fix.
Finally, I found fault soldering, then I resoldering that.
then I could fix it.

based on the product,I have been using this for about 2 years now and is absolutely suited for most electronic projects or repair work stations for electronic businesses. I have not seen any trip switch or circuit breaker on no circuit breaker on the shell of the unit but the gentleman is correct it will go in CC mode or protection mode
