myVolts MCH-302DA 30V 2A Adjustable Digital DC Power Supply

SKU CH-1CQN-0ZK24

Adjustable 0-30V, 0-2A digital DC supply with 51-100W output and full protection for bench testing

  • TypeAT
  • Precise voltage control from 0 to 30 V
  • Adjustable current limit up to 2 A for safe testing
  • Wide 110–220 V input suits global bench use
  • Continuous full-scale operation without derating
  • CE and RoHS certified for regulated environments

Digital bench supply for lab use

The myVolts MCH-302DA is an adjustable digital DC power supply delivering 0 to 30 volts and 0 to 2 amps from a single output. It accepts 110 to 220 volt input at 50 to 60 hertz and provides 51 to 100 watts of output power. The unit measures 275 by 120 by 160 millimetres and carries CE and RoHS compliance.

Suits hobbyists needing basic bench power

This supply suits hobbyists, students and technicians who need a simple variable voltage and current source for circuit testing or battery charging. It is not for users who require multiple isolated outputs, remote programming interfaces or higher current capability beyond the 2 amp limit. Buyers needing rack-mount dimensions or precision calibration certificates should look elsewhere.

Straightforward bench installation

Place the unit on a stable surface, connect the supplied mains lead to a 110 to 220 volt outlet and attach test leads to the front binding posts. The digital display shows voltage and current continuously. Common issues include loose output connections causing voltage drop and accidental short circuits if leads touch while the output is enabled.

Highlights

  • Adjustable current limit up to 2 A for safe testing
  • Wide 110–220 V input suits global bench use
  • Continuous full-scale operation without derating
  • CE and RoHS certified for regulated environments

Questions about this item

What mains voltage does the MCH-302DA require to operate?

The unit accepts an input range of 110-220V at 50-60Hz, so it plugs directly into standard UK or EU mains without an external transformer.

Will the single 0-30V 0-2A output drive a vintage 12V 1A project board safely?

Yes, you can set the voltage to 12V and the current limit to 1A; the supply’s continuous variable control and full-scale protection prevent over-current damage to older boards.

How do I verify the MCH-302DA is regulating correctly after powering up?

With no load connected, adjust the voltage knob and confirm the digital display follows from 0 to 30V; then apply a known resistive load and check the current readout stays within the 0-2A limit.
