KUAIQU SPPS-H3010 30V 10A 300W Adjustable DC Power Supply for Relay & Control Circuit Testing

The KUAIQU SPPS-H3010 is an Adjustable DC Power Supply for Relay and Control Circuit Testing, providing a 0–30V adjustable output and up to 10A current adjustment for low-voltage control circuits and electrically operated components.

Its wide 0–30V range allows engineers to test relay coils, contactors, control modules, switches, and other DC-powered control components at different supply voltages. The 300W output capacity provides additional flexibility when multiple components or larger control loads are involved.

The SPPS-H3010 combines OCP and OVP protection with an independent Output ON/OFF switch. The output can be disabled during wiring and parameter adjustment, helping prevent accidental power delivery and adding an extra layer of protection for the test circuit.

Key Features

  • 0–30V Adjustable Output – Supports different DC voltage requirements for control circuit testing.
  • 0–10A Adjustable Current – Provides flexible current control for control components and loads.
  • 300W Output Power – Suitable for relay, contactor, and control circuit testing.
  • Independent Output ON/OFF Switch – Allows the output to be disabled during setup or adjustment, helping prevent accidental power delivery and adding an extra layer of protection.
  • OCP & OVP Protection – Helps protect control circuits and connected components during testing.
  • USB 5V/2A Output – Provides convenient auxiliary power for USB instruments and accessories.
  • Real-Time V/A/W Display – Allows quick monitoring of the test circuit.
  • Precision Encoder Knob – Enables controlled voltage and current adjustment.

Applications

  • Relay testing
  • Relay coil testing
  • Contactor testing
  • Control circuit testing
