MCH-305D-II Dual Channel Adjustable DC Power Supply – Variable Linear Lab PSU 0-30V 0-5A with Series/Parallel Modes & 4 LED Displays

Overview 

Eliminate the limitations of single-rail bench units with the high-precision MCH-305D-II Dual-Channel Variable Linear DC Power Supply. Engineered specifically for professional lab prototyping, mechatronic troubleshooting, and delicate semiconductor debugging, this heavy-duty unit packs two independent adjustable output channels. Featuring an internal analog linear transformer setup, it yields exceptionally low electrical ripple and high-frequency noise rejection that cheap switching power supplies simply cannot match. With its integrated Series and Parallel tracking modes, you can instantly link both main channels internally to double your working limits to a massive 60V  5A or 30 V 10A at the push of a button!

Key Features 

• Dual Fully-Isolated Channels + Fixed Auxiliary Rail: Offers two independently controlled 0-30V  0-5 A channels alongside an extra fixed 5V  3A terminal designed to directly power standard TTL logic boards or development modules.

• Intelligent One-Touch Hardware Tracking: Front-panel mode switches route internal traces into Independent, Series (60V  5 A), or Parallel (30 V 10A) loops without needing any external jumper wires.

• True 4-Digit Dedicated LED Monitoring: Features four separate high-visibility red LED readouts to constantly display the exact Voltage (V) and Current (A) of both channels simultaneously down to two decimal places.

• Low-Ripple Linear Regulator Topology: Built with high-grade copper toroidal transformers and premium pass-transistors to deliver an incredibly clean, stable DC output line that safeguards sensitive RF modules and analog sensors from electrical noise.

• Rigorous Protective Sub-Systems: Armed with continuous Constant Current (CC) / Constant Voltage (CV) cross-switching logic, along with full Short-Circuit, Over-Current, and Over-Temperature automatic thermal-cutoff protection.
