Computerzone 30V 10A Adjustable DC Power Supply 110V

SKU CH-BYPE-A9EZY

Adjustable 0-30 V, 0-10 A DC supply with dual digital display, CV/CC auto-switching, OVP/OCP/OTP protection and temperature-controlled fan for continuous 24-hour operation

  • Adjustable 0-30V and 0-10A output covers diverse testing needs
  • Dual LED digital display shows voltage and current at 0.1V and 0.1A resolution
  • Automatic CV/CC crossover protects circuits during load changes
  • OVP, OCP and OTP safeguards prevent damage from faults
  • Temperature-controlled fan reduces noise and extends 24-hour full-load operation

Lab bench DC supply

This adjustable bench unit delivers zero to thirty volts and zero to ten amps from a 110 volt AC input. It suits engineers, technicians and hobbyists who need a stable source for prototype testing, battery work or LED development.

Thermals and noise

An intelligent temperature controlled fan varies its speed with the load, keeping acoustic output low during light use. The supply is rated for continuous full load operation over twenty four hours thanks to safe circuit design and quality components.

Build and connections

A durable steel case houses the PWM switching stabiliser with MOS linear adjustment. The front panel provides a dual LED three digit display showing voltage to zero point one volt and current to zero point one amp. Protections include over voltage, over current and over temperature shutdown.

Domande su questo articolo

How do I connect the 110V AC input and what step is often missed?

Plug the supplied power cord into a 110V AC 60Hz outlet within ±10% tolerance; the step often missed is verifying the mains voltage matches the 110V rating before switching on.

What part will need replacement after long 24-hour full-load runs?

The intelligent temperature-control fan is the only moving part; its bearings wear over time and the fan should be replaced when noise increases or speed drops under sustained load.

At what current does the 0.1% + 10mA load-stabilisation limit appear first during continuous use?

In constant-current mode the load-stabilisation specification is 0.1% + 10mA, so the limit shows up at the full 10A output when the supply runs continuously at maximum current.
