YIHUA YH-3005D-II Dual Adjustable DC Power Supply
Description
The 3005D-II power supply is a dual channel DC power supply, and is designed to provide a continuously adjustable current and voltage. The built in, large LED backlit display and rotary switch allows for an easier and clearer operation. The two channels operate individually, and are designed with a track and hold circuit on both series or parallel circuits. This particular power supply has 3 output rates to choose from: 2.5V, 3.3V, or 5V.
This equipment features a streamlined appearance and exceptional performance, making it popular in laboratories, educational institutions, electronic component production, communication industries and more.
1-PRA Parallel Circuit
2-IND Series Circuit
3-SED Individual
4-Power Button
Features
- Three output modes to choose from according to different working conditions. Choice is made using a simple toggle switch.
A. Dual channel individual operation: This means this power supply has two sets of 30V/5A output voltage and current.
B. IND series circuit tracking mode: This means this power supply has a maximum of 60V output voltage and 5A output current.
C. PRA parallel circuit tracking mode: This means this power supply has a maximum of 30V output voltage and 10A output current. - This electronic power supply has 3 sets of rated output modes of 2.5V/3.3V/5V for customers to choose from using a simple switch on the control panel.
- The current accuracy can be controlled within 0.001A.
- The internal voltage transformer is made of high quality copper and built with a fan for heat dissipation when the equipment temperature reaches 45 ℃ in order to prolong its service life.
