Aim-TTi EL155R Digital Bench Power Supply – 75W, 1 Output
The Aim-TTi EL155R Digital Bench Power Supply is a single-channel PSU with a maximum power output of 75W, a voltage range of 0 to 15V, and a current range of 0 to 5A. It features a traditional analogue design for ease of use, as well as new four-digit, fixed-resolution voltage and current meters and switchable remote sensing for greater precision.
Remote Sensing
To ensure true metering of the load and precise regulation at the load, the Aim-TTi EL155R Digital Bench Power Supply includes remote sense terminals integrated into its output. The remote sense terminals can be activated and deactivated at the flick of a switch.
Linear Regulation
The Aim-TTi EL155R Digital Bench Power Supply’s true linear regulation ensures that it can provide the best possible performance. The Aim-TTi EL155R Digital Bench Power Supply has excellent line and load regulation, good transient response, and very low output noise.
Silent Cooling
Additionally, to eliminate fan noise the Aim-TTi EL155R Digital Bench Power Supply utilises convection cooling.
Safety Binding-Post Terminals
Another practical feature present on the Aim-TTi EL155R Digital Bench Power Supply is its output terminals. These terminals have been designed to comply with laboratory safety requirements and to provide maximum connection flexibility. The Aim-TTi EL155R Digital Bench Power Supply’s output terminals can accept 4mm safety plugs with rigid insulating sleeves as well as bare wires and fork connectors.
Simple to Use
Furthermore, the Aim-TTi EL155R Digital Bench Power Supply’s analogue controls ensure that voltage and current levels can be set easily and efficiently without compromising accuracy. The Aim-TTi EL155R Digital Bench Power Supply includes coarse and fine voltage controls as well as a logarithmic current control which enables low current levels to be configured accurately.
Constant Current and Constant Voltage Modes
The Aim-TTi EL155R Digital Bench Power Supply can be set to operate in either Constant Current or Constant Voltage mode with automatic crossover. The Aim-TTi EL155R Digital Bench Power Supply includes a mode indicator.
DC Output On/Off Switch
Preset voltage and current levels can be viewed before connecting a load using the Aim-TTi EL155R Digital Bench Power Supply’s DC output on/off switch.
Four-Digit Meters
Data is visible via the Aim-TTi EL155R Digital Bench Power Supply’s large, backlit display. The four-digit voltage and current meters indicate voltage and current levels to a fixed resolution thereby preventing misinterpretation of readings. The Aim-TTi EL155R Digital Bench Power Supply’s voltage meter has a fixed resolution of 10mV while the current meter has a fixed resolution of 1mA.
The Aim-TTi EL155R Digital Bench Power Supply is a linear, benchtop, single-channel PSU suitable for use in laboratories.
