Aim-TTi EL303R Digital Bench Power Supply – 90W, 1 Output
The Aim-TTi EL303R Digital Bench Power Supply is a single-channel PSU utilising true linear regulation to provide the best possible performance. In addition to this, the Aim-TTi EL303R Digital Bench Power Supply includes switchable remote sensing and four-digit voltage and current meters with fixed resolutions for greater precision. However, it retains the easy-to-use analogue design of its predecessors: the Aim-TTi EL-Series of Digital Bench Power Supplies.
This model can provide a maximum power output of 90W. The Aim-TTi EL303R Digital Bench Power Supply has a voltage range of 0 to 30V and a current range of 0 to 3A.
Constant Current and Constant Voltage Modes
The Aim-TTi EL303R Digital Bench Power Supply’s single output can be programmed to operate in either Constant Voltage or Constant Current mode with automatic crossover. The mode indicator will illuminate when the Aim-TTi EL303R Digital Bench Power Supply is in Constant Current mode.
DC Output On/Off Switch
The user can view preset voltage and current levels before connecting a load using the Aim-TTi EL303R Digital Bench Power Supply’s DC Output On/Off Switch.
Simple to Use
The Aim-TTi EL303R Digital Bench Power Supply features analogue controls to enable the fast, easy, and accurate configuration of voltage and current levels. The Aim-TTi EL303R Digital Bench Power Supply features coarse and fine voltage controls and a logarithmic current control which enables low current levels to be set accurately.
Four-Digit Meters
Voltage and current information are viewable via the Aim-TTi EL303R Digital Bench Power Supply’s large, backlit display. To prevent misinterpretation of measurements, the Aim-TTi EL303R Digital Bench Power Supply is equipped with four-digit, fixed-resolution voltage, and current meters. The Aim-TTi EL303R Digital Bench Power Supply’s voltage meter has a fixed resolution of 10mV and the current meter has a fixed resolution of 1mA.
Remote Sensing
Remote sense terminals are essential for ensuring precise regulation of the load and true metering of the load. The Aim-TTi EL303R Digital Bench Power Supply incorporates remote sense terminals into its output; they can be switched on and off as required.
Linear Regulation
As previously mentioned, the Aim-TTi EL303R Digital Bench Power Supply utilises true linear regulation to provide high performance. As a result, the Aim-TTi EL303R Digital Bench Power Supply is equipped with excellent line and load regulation, good transient response, and very low output noise.
Silent Cooling
Moreover, to eliminate fan noise the Aim-TTi EL303R Digital Bench Power Supply utilises convection cooling.
Safety Binding-Post Terminals
Finally, to ensure compliance with a majority of laboratories’ safety regulations, as well as provide maximum connection flexibility, the Aim-TTi EL303R Digital Bench Power Supply’s output terminals accept 4mm safety plugs with rigid insulating sleeves, as well as bare wires and fork connectors.
The Aim-TTi EL303R Digital Bench Power Supply is a high-performance, practical, and precise PSU.
