  • TypeAT
  • Adjustable 0-30 V and 0-5 A for flexible bench testing
  • Switching regulator delivers >85 % efficiency with low 20 mA ripple
  • LCD shows voltage and current to ±0.5 % accuracy
  • CE certified with over-voltage, over-temperature and anti-shock protection
  • Compact 220×70×160 mm unit weighs about 2 kg

Adjustable DC power supply 0-30 V 5 A

The myVolts MCH-K305D is a switching DC regulator that delivers continuously adjustable output from 0 to 30 volts and 0 to 5 amps with a maximum of 150 watts. It is built for bench work such as electronic repair, experimental circuits and ageing tests where stable, low-ripple power is required.

Check mains voltage and load needs

The unit accepts 110 V or 220 V input at 50 Hz or 60 Hz so verify which mains supply is available at the bench. Ensure the device under test does not exceed 5 A or 150 W and that the operating environment stays within -20 °C to 80 °C with humidity below 90 %. The supply weighs about 2 kg and measures 220 mm deep by 70 mm wide by 160 mm high.

Replaces fixed-voltage bench units

This supply upgrades from single-output adapters when a project demands variable voltage and current with milliamp resolution and ±0.5 % display accuracy. Overvoltage, over-temperature and anti-shock protection plus CE certification make the jump worthwhile for labs that need programmable safety limits and a high-contrast LCD readout.

Questions sur cet article

Does the MCH-K305D include test leads or must they be bought separately?

The MCH-K305D is supplied as the bench unit only; test leads are not included and must be sourced separately.

Should I choose the 110 V or 220 V input version for my bench?

Select the version that matches your mains supply — the unit is built for either 110 V or 220 V operation at 50/60 Hz.

What does the 150 W rating mean when I am driving a 30 V load?

At 30 V the supply can deliver up to 5 A, giving the full 150 W; lower voltages allow the same 5 A up to the power limit.
