Aim-TTi EL301R Digital Bench Power Supply

Description

The Aim-TTi EL301R Digital Bench Power Supply is a single-channel, benchtop PSU with a maximum power output of 30W. It can provide a voltage output of 0 to 30V at 0 to 1A.

The Aim-TTi EL301R Digital Bench Power Supply is an updated version of the Aim-TTi EL301 Digital Bench Power Supply and includes a new four-digit meter and switchable remote sensing. It also offers higher precision whilst retaining its predecessor's simplicity of operation.

Linear Regulation

To ensure the best performance, the Aim-TTi EL301R Digital Bench Power Supply utilises true linear regulation. It has excellent line and load regulation, good transient response, and very low output noise.

Silent Cooling

The Aim-TTi EL301R Digital Bench Power Supply is also completely free of fan noise as it utilises convection cooling.

Constant Current and Constant Voltage Modes

The Aim-TTi EL301R Digital Bench Power Supply’s output can be configured to operate in either Constant Current or Constant Voltage mode. This digital PSU features an automatic crossover and a mode indicator.

Simple to Use

To ensure ease of operation, the Aim-TTi EL301R Digital Bench Power Supply includes analogue controls. The Aim-TTi EL301R Digital Bench Power Supply features coarse and fine voltage controls, as well as a logarithmic current control for setting low currents precisely.

DC Output Switch

Preset voltage and current levels can be viewed before connecting a load using the Aim-TTi EL301R Digital Bench Power Supply’s dedicated DC output on/off switch.

Four-Digit Meters

Data is indicated on the Aim-TTi EL301R Digital Bench Power Supply’s large, backlit display with four-digit, fixed-resolution voltage, and current meters. Fixed resolution prevents misinterpretation of results: the Aim-TTi EL301R Digital Bench Power Supply’s voltage meter has a fixed resolution of 10mV while its current meter has a fixed resolution of 1mA.

Remote Sensing

To ensure precise regulation of the load and true metering of the load voltage, the Aim-TTi EL301R Digital Bench Power Supply’s output includes remote sense terminals that can be enabled and disabled at the flick of a switch.

Safety Binding-Post Terminals

The Aim-TTi EL301R Digital Bench Power Supply’s output terminals have been designed to ensure that they can accept 4mm safety plugs with rigid insulating sleeves, as well as fork connectors and bare wires. As a result, the Aim-TTi EL301R Digital Bench Power Supply complies with laboratory safety requirements without compromising flexibility.

The Aim-TTi EL301R Digital Bench Power Supply is a precise, reliable, and adaptable PSU suitable for various benchtop applications.
