SK3323/3325/3503

Programmable Linear DC Power Supply


Feature

The SK33XX series programmable linear DC power supplies have three independent outputs – two sets of adjustable voltage/current and a fixed set of selectable voltage1.8V, 2.5V, 3.3V and 5V. it has three available operation modes–independent, series and parallel modes. All make this series become a high performance-to-price ratio instrument.

Programmable Linear DC Power Supply Key Features:

Linear Regulation:

Stable Output: Provides highly stable and low-noise DC output.

Low Ripple and Noise: Ideal for sensitive analog and RF circuits.


Programmability:

Remote Control: Can be controlled via various interfaces such as USB, Ethernet, GPIB, or RS-232.

Software Integration: Compatible with software for automation, data logging, and complex sequencing.

User-Defined Settings: Ability to set and recall voltage, current, and protection settings.


Precise Adjustment:

Fine Resolution: Allows fine-tuning of output voltage and current with high precision.

Multiple Ranges: Often provides multiple voltage and current ranges to accommodate different requirements.


Protection Features:

Overvoltage Protection (OVP): Protects connected devices from excessive voltage.

Overcurrent Protection (OCP): Limits current to prevent damage to the power supply and the device under test.

Thermal Protection: Shuts down the power supply in case of overheating.


Display and Controls:

Digital Display: Provides real-time readings of output voltage, current, and power.

Intuitive Interface: User-friendly front panel controls for manual operation.


Multiple Output Channels:

Some models offer multiple independent output channels, each programmable, to power several devices simultaneously.
