Rigol DP832 Lab Power supply

DP832

Introducing the Rigol DP832 Programmable Linear DC Bench Power Supply, a robust unit that seamlessly combines functionality and convenience..

 

Introduction - the Rigol DP832: A Distinctive Powerhouse:

As soon as you power it on, the audible hum of its fan attests to the substantial transformer within, a testament to its linear power supply design. The immediate fan activation hints at potential temperature-sensitive adjustments..

Front Panel Ingenuity: A Closer Look at Design Details:

Venturing to the front panel, a thoughtful touch is the inclusion of an IEC lead, facilitating easy placement in confined spaces. Now, let's delve into the user interface. At the bottom, three channels beckon—one accommodating up to 5 volts, while the other pair offer isolation at a maximum of 30 volts each. However, note that channels 2 and 3 share a common, providing two isolated supplies and one with a common supply.

Seamless User Control: Navigating the Intuitive Interface:

Navigating the intuitive interface reveals a graphic display for each channel, simplifying voltage and current parameter adjustments. The jog wheel facilitates swift changes, allowing for precise control. The absence of remote voltage sensing terminals is notable, but given its low current capacity of three amps per channel, the decision is pragmatic.

Versatility Unleashed: Exploring Back Panel Features:

A closer look at the back panel unveils voltage selection switches and various interfaces, including optional RS-232, GPIB, USB host, and USB device connections. These interfaces cater to automation, expanding the power supply's utility for diverse applications.

Configurations Galore: Maximizing Power Supply Flexibility:

The unit's versatility shines through in its ability to create split rails or stack supplies in series or parallel configurations. While the multitude of features may initially seem overwhelming, the review explores the save and recall feature as a remedy, ensuring efficient setup for varied testing scenarios.

Safety First: Efficient Power Control Mechanisms:

The physical design also garners praise, with an easily accessible "all off" button providing a quick power cut to all channels—a valuable safety feature. A two-step process for turning all channels on adds an extra layer of control.

In-Depth Performance Analysis: The Rigol DP832 in Action:

In summary, the Rigol DP832 impresses with its user-friendly interface, efficient controls, and versatility. Despite a slight adjustment period for the radial button menu, the layout's logic becomes apparent. The display, with its clear visualization of channel statuses, contributes to an overall positive user experience.

Empowering Makers: Recommendations for Practical Use:

With a maximum power output of 195W and specific features like low ripple and noise, fast transient response time, and precise regulation rates, this power supply caters to the serious maker or amplifier enthusiast. Its capability to generate split rails makes it a valuable tool for those engaged in amplifier work or design, earning a solid recommendation for anyone seeking a reliable, general-purpose power supply for their bench.
