Product Description

 Brand New YH-305D Digital DC Power Supply Precision Variable Adjustable Lab Grade 30V 5A

To All of Our Dear Customers

• All of our products are directly from original manufacturer;
• All of them have good quality, competitive price, perfect technical support, and perfect after-service;
• All of them have 12 months warranty!
• Please bid it with full confidence!

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 supply.(some of factory transformer material less efficient that can not load, so their make bigger. that cause the weight heavy and high calorific value, so there are transformer can not compete us.)

Features:

• High stability
• Overall current output protection
• Current and Voltage can adjustable
• Current A and MA conversion
• Current and voltage are smooth and not gear regulation
• LED digital display shows current and voltage value
