China Variable DC Power Supply

Variable DC Power Supply (0-30V / 0-3A)
303D communication maintenance power supply is a single line output of stabilized
high accuracy DC stabilized power supply. The output voltage and current can
be adjusted continuously within the rated range. The load current has MA
conversion with two settings: 0-3A and 0-99 mA. Constant voltage and constant
current (CV/CC), automatic switching of working modes. Double digital display
shows output voltage and current independently. Several protection functions include
currentlimitation, voltage reduction, short circuit protection,
over-temperature protection,etc. The design is applied to production line of
the plant, maintenance, laboratories and is also a necessary devicefor the
communication industry.
Primary Technical Parameter
1. The power supply input 110V/220V/230V/240V AC
2. Output voltage 0-30V /3A
3. Work temperture -10oC-40oC
4. Empty carry to exhaust <0.25W
YH-303D DC regulated power supply with CE, 0~30V / 0~3A Mini 30V/3A power
supply, switching power supply, DC power supplies.
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 effcient 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 thier make bigger. That cause the weight heavy and high calorific value,
so there are transformer can not compete us. )
These are 220V units you may need a transformer to use the machine in your country. We also do accept special orders for 110V units

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 .

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.
