myVolts 30V 5A Digital Programmable Power Supply

SKU CH-60MZ-E4ANG

Adjustable 0-30V/5A DC output with 10mV/1mA resolution, CV/CC modes, OVP/OCP protection, five presets, keypad lock and temperature-controlled fan

  • Product typeAT
  • Precise 0-30 V output with 10 mV resolution
  • Accurate 0-5 A current control at 1 mA steps
  • Programmable OVP and OCP protect connected loads
  • Five memory presets recall settings instantly
  • Keypad lock prevents accidental parameter changes

Professional DC power supply for lab and bench use

This programmable unit delivers continuously adjustable 0-30V output at up to 5A with 10mV and 1mA resolution. Setup accuracy is better than 0.05% plus 20mV for voltage and 0.1% plus 3mA for current. It operates from 220V mains at 50-60Hz and is rated for ambient temperatures from 32 to 104°F.

Five user presets and keypad lock streamline

Built-in parameter storage lets engineers recall five programmed voltage and current combinations instantly. Configurable over-voltage and over-current protection thresholds guard connected loads, while the keypad lock prevents accidental changes during long runs. An output on/off switch adds another layer of control.

Intelligent fan and compact bench form factor suit

Temperature-controlled cooling keeps acoustic noise low across the 32-104°F operating range. The unit accepts standard 220V input and provides a single DC output channel with CV/CC mode indicators. Storage tolerances extend to 158°F and 70%RH for shelf life between projects.

Questions about this item

Will the cooling fan need cleaning or replacement after long use?

The unit uses an intelligent temperature-controlled fan that speeds up only when needed, reducing wear and noise during extended operation.

What limits continuous output at the full 30 V and 5 A?

The supply is rated for continuous operation up to 40 °C ambient; above that temperature the protection circuits will reduce output to stay within safe limits.

How much heat and noise should I expect when it runs all day at high load?

Ripple stays below 1 mV RMS and the fan runs quietly at low speeds until internal temperature rises, keeping both heat and acoustic output low.
