YIHUA 305DA dc regulated power supply

YIHUA 305DA dc regulated power supply feature

1.have 4 digital display show the voltage and current value,it shows value very very precision .
2.it can adjustable the current protection value directly, audio-visual,it operation convenience .
3.the device have 3 groups output for current and voltage,so you can use 3 groups output working in the same time.
4.the machine arts and crafts is SMT ,all use the latest technique .
5.you can turn off the output ,set the protection current and voltage,this way can protection you test device.

Our warranty

*Credit Safeguard

GuangZhou YiHua Electronic Equipments Co,. Ltd was signed a contract with Alibaba and paid a large deposit, make buyers fee l 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

As usual, 1~16pcs are 1~3 days will ship out . Made in time, fresh from the assembly line.

Over 100~over 500pcs 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.

*Warranty policy

One Years warranty

As usual, the shipping fee are high. if return China to repair are not worth the money. So we could support technology and give you the spare parts along with the product .

Note warranty does not cover wearing parts, for example iron heater, gun heater ,iron tips.

*Products discount

as usual we quote three price for each model sample price, over 60pcs price, over 500pcs price.

Those price are calculate our produce cost, as you know big order are less margin to sell. we hope take win-win business with both.

*Warm-heart note

1.If products upgrade or quality improve to change the technique parameter, the factory will not further notice.

2.If the customer haven't special request, the product in accordance with factory's setting quality standards to produce.
