Aim-TTi EL183R Digital Bench Power Supply

Description

The Aim-TTi EL183R Digital Bench Power Supply is a single-channel, benchtop PSU suitable for use in laboratories. It can provide a maximum power output of 60W and has a voltage output of 0 to 18V at 0 to 3.3A.

The Aim-TTi EL183R Digital Bench Power Supply is an upgraded version of the Aim-TTi EL183 Digital Bench Power Supply; it differs from its predecessor in regards to the inclusion of switchable remote sensing and four-digit, fixed-resolution voltage and current meters. As a result, the Aim-TTi EL183R Digital Bench Power Supply can offer higher precision than its predecessor without compromising ease of use.

Linear Regulation

To ensure high performance, the Aim-TTi EL183R Digital Bench Power Supply uses true linear regulation providing excellent line and load regulation as well as good transient response and very low output noise.

Remote Sensing

One of the new features present on the Aim-TTi EL183R Digital Bench Power Supply is switchable remote sensing. Remote sense terminals integrated into the output can be switched on and off as required; they ensure precise regulation of the load and true metering of the load voltage.

Four-Digit Meters

Also working to improve precision and reliability is the Aim-TTi EL183R Digital Bench Power Supply’s large, backlit display with four-digit, fixed-resolution voltage, and current meters. Fixed resolution (10mV and 1mA) prevents results from being misread.

DC Output On/Off Switch

The Aim-TTi EL183R Digital Bench Power Supply’s DC output on/off switch allows the user to view preset voltage and current levels before connecting a load.

Simple to Use

Voltage and current levels can be configured using the Aim-TTi EL183R Digital Bench Power Supply’s easy-to-use yet accurate analogue controls. The Aim-TTi EL183R Digital Bench Power Supply features coarse and fine voltage controls, as well as a logarithmic current control for setting low currents precisely.

Constant Current and Constant Voltage

The Aim-TTi EL183R Digital Bench Power Supply’s output can be set to operate in either Constant Current or Constant Voltage mode. It is equipped with an automatic crossover and features a mode indicator.

Safety Binding-Post Terminals

To ensure maximum flexibility and maintain compliance with safety regulations, the Aim-TTi EL183R Digital Bench Power Supply’s output terminals have been designed to accept fork connectors, bare wires, and 4mm safety plugs with rigid insulating sleeves.

Silent Cooling

Finally, the Aim-TTi EL183R Digital Bench Power Supply utilises convection cooling eliminating fan noise.

The Aim-TTi EL183R Digital Bench Power Supply is a practical, precise, high-performance PSU optimised for benchtop applications in laboratories.
