One-Key Series/Parallel DC Supply for Relay Coil Testing NICE-POWER SPS305-2KD 0-30V 0-5A 150W×2

Adjustable Dual Channel DC Power for Relay Coil and Driver Circuit Testing

Key Features

Dual Independent Outputs for Testing Relay Coils and Related Circuits

Relay coil testing requires a suitable DC supply to energize coils according to their rated voltage and current. The NICE-POWER SPS305-2KD provides two independently adjustable output channels, each delivering 0–30V, 0–5A, and up to 150W.

The dual-channel design allows users to power two separate relay coils or related electronic circuits from one bench DC supply. Each channel can be adjusted independently, making it convenient to work with different coil voltage requirements and compare the power supply conditions of separate test circuits.

One-Key Series and Parallel Modes for Flexible Output Requirements

Relay coils and their driver circuits may have different voltage and current requirements. The SPS305-2KD supports independent, series, and parallel output modes, giving users more flexibility when configuring DC power for different testing tasks.

With one-key series and parallel switching, users can change the output configuration without complicated external wiring. Series mode provides up to 60V at 5A, while parallel mode provides up to 30V at 10A. A dedicated series-parallel output port makes the connection process more convenient.

Encoder Adjustment with Clear Voltage, Current, and Power Display

When testing relay coils, setting the appropriate supply voltage and monitoring current consumption are important parts of evaluating the coil's electrical operating conditions.

The SPS305-2KD features encoder adjustment for convenient voltage and current setting, together with a four-digit digital display for voltage, current, and power. Its CV/CC indicators show whether the power supply is operating in constant voltage or constant current mode, helping users observe output conditions during coil energization and driver circuit testing.

Negative, Zero, and Positive Voltage Output for Different Circuit Configurations

Some relay-related electronic circuits may require different voltage polarities during development and testing. The SPS305-2KD supports negative voltage–zero voltage–positive voltage output mode, providing additional flexibility for compatible circuits with different polarity requirements.

This function can be useful when developing and evaluating relay driver circuits and other electronic control circuits that require different voltage configurations.

Built-In USB 5V/2A Output for Convenient Auxiliary Power

In addition to its two adjustable DC output channels, the SPS305-2KD includes a USB 5V/2A power output. It provides a convenient auxiliary power source for compatible USB-powered devices used at the workbench, while keeping both adjustable DC channels available for relay coil and circuit testing.

Applications

DC Relay Coil Energization and Voltage Testing

Suitable for supplying adjustable DC power to relay coils during development and electrical testing. Users can set the output voltage according to the coil's rated specifications and monitor the voltage, current, and power readings while the coil is energized.

Testing Relay Coils with Different Power Requirements

For projects involving relay coils with different rated voltages or current requirements, the two independent output channels allow users to configure separate power settings in one unit. This is convenient for testing different coil circuits without repeatedly changing the settings of a single output channel.

Relay Driver Circuit Development and Testing

Provides adjustable DC power for relay driver circuits and their supporting electronic components. Engineers can configure the supply voltage and current according to the circuit requirements when carrying out initial power-up, troubleshooting, and prototype verification.

Relay Control Circuit and Laboratory Prototyping

Suitable for laboratory work, electronic control circuit development, and relay-related prototypes. The independent outputs and one-key series/parallel modes offer flexible power configurations for different circuit arrangements within the specified voltage, current, and power limits.
