Aim-TTi EL302RD Digital Bench Power Supply

Description

The Aim-TTi EL302RD Digital Bench Power Supply is a dual-output PSU utilising true linear regulation. Each of the Aim-TTi EL302RD Digital Bench Power Supply’s channels has a maximum power output of 120W, a voltage range of 0 to 30V, and a current range of 0 to 2A.

Dual Output

The Aim-TTi EL302RD Digital Bench Power Supply’s independent and isolated outputs can be used individually to provide a power output of 120W. Alternatively, the outputs can be wired in series or parallel to provide voltages up to 60V, currents up to 4A, and a maximum power output of 240W.

DC Output On/ Off Switch

Each of the Aim-TTi EL302RD Digital Bench Power Supply’s outputs is equipped with its own DC output on/ off switch allowing them to be controlled independently. Furthermore, using these switches the user can view the preset voltage and current levels for each channel before connecting a load.

Simple to Use

Additionally, both channels feature dedicated analogue voltage and current controls for configuring parameters easily, quickly, and accurately. Both channels feature coarse and fine voltage controls as well as a logarithmic current control which allows low current levels to be set precisely.

Constant Voltage and Constant Current Modes

The Aim-TTi EL302RD Digital Bench Power Supply’s outputs can be programmed to operate in either Constant Current or Constant Voltage mode with automatic crossover. When the mode indicator is illuminated this means the channel is in Constant Current mode.

Four-Digit Meters

In addition to dedicated analogue controls and a DC output on/off switch, each of the Aim-TTi EL302RD Digital Bench Power Supply’s outputs has its four-digit, fixed-resolution voltage, and current meters. Fixed resolution prevents the misinterpretation of readings: the voltage meters have a fixed resolution of 10mV and the current meters have a fixed resolution of 1mA.

Voltage and current meters for each channel are visible via the Aim-TTi EL30RD's large, backlit displays.

Remote Sensing

To ensure true metering of the load as well as precise regulation at the load, both of the Aim-TTi EL302RD Digital Bench Power Supply’s outputs incorporate remote sense terminals. Both outputs also include a switch for turning the remote sense terminals on and off as required.

Linear Regulation

Excellent line and load regulation, good transient response, and very low output noise are provided by the Aim-TTi EL302RD Digital Bench Power Supply’s true linear regulation. Additionally, the Aim-TTi EL302RD Digital Bench Power Supply’s true linear regulation ensures that it can provide the best possible performance.

Silent Cooling

Furthermore, the Aim-TTi EL302RD Digital Bench Power Supply’s convection cooling eliminates fan noise.

Safety Binding-Post Terminals

The Aim-TTi EL302RD Digital Bench Power Supply’s output terminals can accept 4mm safety plugs with rigid sleeves, bare wires, and fork connectors. This ensures it is compliant with the safety regulations of most laboratories without compromising its flexibility.

Moreover, each of the Aim-TTi EL302RD Digital Bench Power Supply’s outputs is short-circuit-proof and protected against external voltages and reverse currents.

The Aim-TTi EL302RD Digital Bench Power Supply is a dual-output PSU suitable for a variety of benchtop applications in laboratories.
