YIHUA 4 Digital precise display current value PSN-305D 30V/5A variable dc power supplyMain Function
1.Output constant current adjustable.
2.Output constant voltage adjustable.
3.LED voltage and current display.
4.Constant voltage and current operation in individual.
5.Over current protection.
6.Current and voltage regulation are smooth and not gears regulation.
7.4 Digital precise display current value,prescise current value mA.
*Primary Technical Parameter
1.The power supply input we can make 110V,220V ,230V, 240V AC
2.Output voltage 0-30V DC adjustable
3.Output current 0-5A ajustable,4 Digital precise display current value,prescise current value mA.
4.Adjustable DC Regulators power supply is specilized for laboratory, school, factory production lines, engineering, maintenance units designed to use, the output voltage between 0 to nominal value continuously adjustable.Also the output load current from 0 to nominal value continuously adjustable, power stability and ripple factor are very good, and a perfect protection circuit, power supply can also be used both as a steady flow power supply.
5.The outlook appearance is pretty
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 competeus.)
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
Over 100~over500pcs are 20days will ship out. Over 1000pcs are 30days .
