discoverzone Adjustable Power Supply 30V 10A 110V

SKU CH-B7WQ-4487K

Adjustable DC power supply delivering 0–30 V at up to 10 A from a 110 V AC input

  • Adjustable 0–30 V DC output covers diverse lab needs
  • 10 A maximum current powers demanding circuits
  • PWM switching with MOS linear adjustment keeps voltage stable
  • Automatic CV/CC changeover protects load and supply
  • Triple protection: over-voltage, over-current, over-temperature

Adjustable 30 V 10 A DC Supply

This bench power supply delivers continuously adjustable DC output from 0 to 30 V at up to 10 A. It runs from a 110 V AC, 60 Hz mains input and uses PWM switching with MOS linear adjustment for stable regulation. The unit operates in constant-voltage and constant-current modes with automatic crossover.

Replaces Fixed-Voltage Adapters

Unlike single-rail wall warts, this instrument lets you dial the exact voltage a prototype or repair job needs. The upgrade is worth it when a project demands repeatable current limiting, over-voltage, over-current and over-temperature protection, or when you must switch between C.V. and C.C. operation without rewiring.

For Hobbyists and Repair Techs

Engineers who need programmable remote control, higher power density or multi-channel output should look elsewhere. The supply suits benches where manual knob adjustment, a durable steel enclosure and basic safety protections cover daily breadboarding, battery simulation and module testing.

Questions about this item

What AC input voltage and frequency does the 30V 10A supply require?

The unit operates from 110 V AC ±10 % at 60 Hz, so a standard North American mains outlet is sufficient.

How do I switch between constant-voltage and constant-current modes on this supply?

The supply automatically changes between C.V. and C.C. operation; set the voltage and current limits, and the mode transitions when the load reaches the current limit.

Which protections will shut the unit down if a fault occurs?

Built-in safeguards include over-voltage (OVP), over-current (OCP) and over-temperature (OTP) protection that disable the output until the fault clears.
