Key Features

High-Resolution Current Measurement for Sensor Testing

For low-power sensors and precision circuits, small current variations can indicate important operating changes. The SPPS-K305 supports automatic A/mA range switching with 10μA readback resolution (<20mA range), allowing engineers to capture subtle current fluctuations during sensor calibration and fault analysis.

Precise and Stable Output for Reliable Calibration

With 1mV voltage setting resolution and excellent regulation performance, the SPPS-K305 provides stable power output to reduce measurement errors caused by voltage fluctuations.

• Voltage setting resolution: 1mV
• Current setting resolution: 1mA
• Voltage accuracy: 0.05% + 10mV
• Current accuracy: 0.1% + 10mA

Ideal for powering:

• Temperature sensors
• Pressure sensors
• Industrial transmitters
• IoT sensor modules
• Embedded control circuits

5-Digit Display for Accurate Data Monitoring

The high-resolution 5-digit display provides clear and stable readings, helping engineers monitor real-time voltage and current changes during calibration procedures and avoid inaccurate test results.

Quick Parameter Recall for Repeated Testing

The built-in 4 groups of memory storage allow users to save frequently used test parameters and quickly switch between different sensor test conditions, improving efficiency in production testing and laboratory development.

Safe Operation with Complete Protection System

The SPPS-K305 integrates multiple protection functions to protect both the power supply and connected devices:

• Over Voltage Protection (OVP)
• Over Current Protection (OCP)
• Short Circuit Protection

These protections help prevent damage during sensor wiring, prototype testing, and debugging operations.

Direct Current Setting Before Output Enable

Users can preset voltage and current values before enabling output, eliminating the need for temporary short-circuit adjustments and providing a safer workflow during sensor testing.

Smooth Encoder Adjustment & Panel Lock

The precision encoder provides finer and smoother parameter adjustment compared with traditional knobs. The panel lock function prevents accidental changes during long-term testing or calibration processes.

Dual USB & Type-C Charging Ports

Equipped with 5V/2A USB and Type-C outputs, the SPPS-K305 can directly power or charge small electronic devices, development boards, and portable test equipment.

Adjustable Key Tone for Different Working Environments

The adjustable key sound with mute function makes the power supply suitable for both quiet laboratories and industrial workshops.
