Principle description of constant voltage/constant current CV/CC The operation mode of constant voltage/constant current can be automatically switched depending
on the comparison result of the load current and limited current value.
a) Constant voltage CV
When the existing current value is smaller than the set output limit current value, the power supply
is working under the constant voltage mode. The CV indicator light on the front panel is on, the
output voltage is controlled and it will be the same as the set value. Current changes with the load.
b) Constant current mode (CC)
When the current value exceeds the limit value of the output current, the equipment will work in the
CC mode. The CC indicator light on the front panel is on, the output current value is controlled to
the set value. Since the limited output power cannot be overloaded, the output voltage can be lower
than the set value. When the output current is lower than the set value, the equipment will
automatically change to CC mode.
Main fuction
1.Output constant current adjustable.
2.Output constant voltage adjustable.
3.LCD voltage and currrent display.
4.Constant voltage and current operation in individual.
5.Over current protection.

The advantages of our DC power supply
1.High precision and good technique to protect the product Safety and reliability.
We are using advanced SAMSUNG IC according control software to shows. And in order to protect the product Safety and reliability, in software we make the Limit in the shows.
(Some of factory products in order to save the cost are using Analog Circuitry to do,so their are precision Safety and reliability can not compete us.)
2.Good transformer
Our transformer are using good conductor and high efficient magnetic core.So we no need make bigger ,but can satisfied the DC power suppy.
(some of factory transformer material less efficient that can not load, so they make bigger. that cause the weight heavy and high calorific value, so their transformer can not compete ![]()

Our warranty
*Credit Safeguard
GuangZhou YiHua Electronic Equipments Co,. Ltd was signed a contract with Alibaba and paid a large deposit, make buyers feel comfortable buying
*Factory advantage
Factory D&R / production/ sales/ and sales service together.
Manufactory sell directly,the goods are in plenty supply,delivery date fast,good compete price You could arrange to ship the goods by your self , or ask we help you arrange to ship. If we help you arrange to ship. Before quote the shipping freight, we need to know which model and quantity you are asking. We will according your detail address, order model and quantity to advise you ship by sea or, by air ,or by Express. As usual, we are using HongKong DHL to ship the small order..
*Delivery date
Over 100~over500pcs are 20days will ship out. Over 1000pcs are 30days .
If the material not enough or we have some customer queue up our products before you,
we will discuss with you the shipping date. If you want the delivery date faster than that day, please inquiry us, we will try to do it as your request.
