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.
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.
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.
Additionally, to eliminate fan noise the Aim-TTi EL155R Digital Bench Power Supply utilises convection cooling.
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.
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.
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.
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.
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.
