Linear DC Power Supply DPS45
The DPS series are linear DC power supplies with 4 channels, two main channels with 0~30V/0~50V output and two auxiliary channels with 2.2~15V output. Auto series and parallel operations double output voltage and current in the main channels (CH1/CH2). Auxiliary channels (CH3/CH4) can also be connected through external test leads to double output voltage and current. Automatic cooling fan control give sufficient cooling to the power supply and minimize fan noise. The output ON/OFF control and preset voltage & current function protect the power supply and related loads from unexpected damages. The DPS series are widely used in applications of powering operational amplifier, push pull stages, logic circuit and definition systems.

Clean, Stable Power for Sensitive Electronics: Linear DC Power Supply DPS45
Deliver ultra-low-noise, highly stable DC power for precision applications with the Linear DC Power Supply DPS45—a benchtop constant voltage/constant current (CV/CC) power supply engineered for laboratories, R&D, education, and electronics testing. With 0–45V voltage and 0–5A current output, the DPS45 uses a linear regulation design to provide exceptionally clean power (<0.5 mV RMS ripple)—making it ideal for powering sensitive analog circuits, sensors, op-amps, and low-noise amplifiers where switching noise is unacceptable.
Engineered for Purity, Precision, and Protection
Unlike switching power supplies, the DPS45 Linear DC Power Supply eliminates high-frequency noise and electromagnetic interference (EMI), ensuring signal integrity in critical measurements. Its dual displays show real-time voltage and current simultaneously, while coarse/fine adjustment knobs allow precise tuning. Comprehensive protection features—including over-voltage (OVP), over-current (OCP), and over-temperature (OTP) safeguard both the device under test and the power supply itself.
- Output Range: 0–45V / 0–5A (225W) – Suitable for a wide range of low- to medium-power DC applications.
- Ultra-Low Ripple & Noise: <0.5 mV RMS – Linear design ensures clean power for noise-sensitive circuits.
- CV/CC Auto Crossover – Automatically switches between constant voltage and constant current modes for adaptive load protection.
- Analog Meters with Digital Display Option – Clear, real-time monitoring of output parameters.
- Robust Metal Enclosure with Binding Posts – Durable construction; accepts banana plugs, spade lugs, or bare wires.
- CE & RoHS Certified – Complies with international electrical safety and environmental standards.
Trusted in Education, Prototyping, and Precision Testing
From powering student electronics projects and calibrating instrumentation to biasing photodiodes or testing battery management systems, the DPS45 provides the stable, quiet power required for repeatable results. Its simplicity, reliability, and low electromagnetic interference make it a staple in teaching labs, engineering workshops, and R&D benches.
When your application demands purity over efficiency, the Linear DC Power Supply DPS45 delivers performance you can trust—every volt, every amp.
Clean power. Zero noise. Total confidence.
