120V 3A 360W×2

Dual Output DC Power Supply for Railway Signal Module Testing

The NICE-POWER SPS1203-2KD dual channel DC source provides adjustable DC power for railway signal module testing and related electronic control circuit evaluation. With two independent output channels, each offering 0–120V, 0–3A, and 360W, it allows technicians to configure separate voltage and current settings for compatible railway signal modules and their associated DC circuits.

For different testing requirements, the SPS1203-2KD supports one-key series and parallel output modes. The series configuration provides up to 240V, while the parallel configuration provides up to 6A. Combined with encoder adjustment, fine voltage and current resolution, and dedicated series-parallel output terminals, this bench power supply offers flexible DC power configurations for railway signal module evaluation, control circuit maintenance, and electronic component testing.

Key Features

Dual Independent Outputs for Railway Signal Module Testing

The SPS1203-2KD features two independent DC output channels, each rated at 0–120V, 0–3A, and 360W. Both channels can be adjusted separately, providing flexible power supply options when testing different railway signal modules, control boards, or related electronic circuits on a workbench.

Adjustable 0–120V DC Output for Signal Control Circuit Evaluation

Each channel provides an adjustable 0–120V DC output, allowing users to select suitable voltage and current settings according to the requirements of compatible railway signal control modules. This flexibility supports bench evaluation of DC-powered signal electronics and related control circuits under different supply conditions.

One-Key Series Mode for Higher-Voltage DC Testing

When a higher DC voltage is needed, the two channels can be combined through the one-key series function. The series mode provides an output range of 0–240V at up to 3A, with a total rated power of 720W. This configuration offers additional voltage flexibility for compatible higher-voltage signal modules and related DC circuit testing.

One-Key Parallel Mode for Higher-Current Testing

For applications requiring a higher output current, the one-key parallel function combines the two channels to provide 0–120V and up to 6A, with a total rated power of 720W. This mode provides greater current capacity for compatible DC-powered railway signal components and control circuits.

Fine Voltage and Current Setting and Readback Resolution

The SPS1203-2KD supports voltage setting and readback resolution of 10mV below 100V and 0.1V at or above 100V. The current setting and readback resolution is 1mA. These specifications allow technicians to set and monitor detailed voltage and current values during railway signal module bench testing.

Encoder Adjustment for Convenient Output Setting

The encoder adjustment design makes it convenient to set output voltage and current during testing. Technicians can adjust the DC source according to the electrical requirements of the railway signal module or control circuit being evaluated.

Dedicated Series-Parallel Output Terminals

Dedicated series-parallel output terminals simplify the connection process when using series or parallel configurations. They help reduce complicated external wiring when switching between the supported output modes.

Negative-Zero-Positive Voltage Output Mode

The power supply supports negative-zero-positive voltage output, providing additional flexibility for compatible signal control circuits and electronic components that require different voltage polarities during bench evaluation.

Built-In 5V / 2A USB Output

A standard 5V / 2A USB output port is included for compatible USB-powered devices, providing an additional power option for the testing workbench.
