YIHUA 305DB variable dc power supply , multiple / triple / dual output dc power supply

YIHUA 305DB variable dc power supply, multiple / triple / dual output dc 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 ,audio-visual,it operation convenience .

3.the device have 3 groups positive and negative current and voltage output connector,so you can use 3 groups output working in the same time,but please pay attention to it,the total current can't

over the machine current,it means can not over 5A,please note.

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.

YIHUA 305DB variable dc power supply, multiple / triple / dual output dc power supply, have above all YIHUA305DA features and merit ,and additional to the following features

1.it store up 60 groups current and voltage value,you can set you want to use value,very very convenience.

2.the device can use software through the computer control the machine,you can use computer set all current and voltage value.

3.it through computer long-distance control the device,but also have Programming function ,if you need use it.

4.YIHUA305DB the current can though the knob adjustable current protection ,more audio-visual,it operation more convenience .

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.
