Product Information

Full details

The Aim-TTi EX354RT is a versatile 305W triple output power supply designed for bench-top users seeking high precision and performance without complexity. Its hybrid switch-mode pre-regulation and linear post-regulation design offers excellent stability and low noise, comparable to all-linear systems. While it provides advanced features like four-digit meters and remote sensing, users should be aware that the third output has a fixed current limit.

FAQs

What is the difference between the main outputs and the third output?

The two main outputs (typically designated as 1 & 2) offer fully adjustable voltage and current, with CV/CC operation and remote sensing. The third output (typically 3) is fully variable between 1.5V and 5.0V but has a fixed current limit of 5A and may not have all the advanced features of the main outputs.

How does remote sensing improve performance?

Remote sensing compensates for voltage drops along the output leads between the power supply and the load. By measuring the voltage directly at the load terminals, it allows the power supply to adjust its output to maintain the set voltage accurately at the load itself.

What does Constant Voltage/Constant Current (CV/CC) mean?

It means the power supply can operate in two modes: regulating the output to a set voltage (CV) or regulating the output to a set current limit (CC). It automatically switches between these modes depending on the demands of the connected load, indicated by LEDs on the front panel.

Can I connect multiple loads to a single output?

Yes, as long as the combined load does not exceed the voltage and current capabilities of that specific output. Ensure the total current draw does not surpass the set current limit or the maximum capacity of the output.

What is the warranty period for the EX354RT?

Please refer to the official Aim-TTi product documentation or contact your retailer for the most current warranty information.

How do I reset the power supply if it behaves unexpectedly?

The simplest reset is to turn off the main AC power, disconnect the load, wait for a minute, and then power it back on. For persistent issues, consult the user manual or contact support.

Troubleshooting

Unit does not power on

Check that the power cord is securely connected to both the unit and a functioning AC outlet. Ensure the main power switch (if applicable) is in the 'on' position.

Output voltage is inaccurate or unstable

Verify that remote sensing is enabled if used and that the sense leads are properly connected. Ensure the load is within the specified current limits. Check if coarse and fine voltage controls are set correctly.

Current limit is not functioning as expected

Confirm that the current limit control is adjusted to the desired setting. Ensure the unit is in Constant Current (CC) mode, indicated by the CC light. Note the fixed current limit on the third output.

Meters show erratic readings

Ensure all input and output connections are secure and free from corrosion. Check for any potential electromagnetic interference sources nearby.

Pros and Cons

Pros

  • High performance comparable to all-linear designs at an affordable price.
  • Precise metering with four-digit displays for accurate voltage and current readings.
  • Remote sensing capability for accurate load regulation.
  • Independent control and CV/CC operation for each main output.
  • User-friendly interface with simple operation.

Cons

  • Third output has a fixed current limit of 5A.
  • Can be heavier than some purely switch-mode power supplies.
  • May have a higher noise floor than a purely linear design in extreme cases.

Setup, Compatibility & Care

Setup:

  1. Connect the power supply to a suitable AC mains outlet using the provided power cord.
  2. Familiarize yourself with the controls for each output: voltage (coarse/fine), current limit, remote sense switches, and DC on/off switches.
  3. Connect your load to the output terminals using appropriate wiring. Ensure the connectors are secure.
  4. Press the DC on/off switch for the desired output to enable power.
  5. Adjust voltage and current settings as required, utilizing the meters for feedback.

Compatibility:

The EX354RT is compatible with a wide range of electronic loads and devices that fall within its voltage and current specifications. The output terminals are designed to accept various connection types, including 4mm safety plugs, fork connectors, and bare wires.

Care:

  • Keep the unit in a well-ventilated area to prevent overheating.
  • Regularly clean the exterior with a soft, dry cloth. Avoid using solvents or abrasive cleaners.
  • Periodically check the ventilation slots for dust accumulation and clean gently if necessary.
  • Ensure all connections are clean and secure to maintain optimal performance.
