Aim-TTi EX354RT 305W Triple Output PSU

This Aim-TTi EX354RT 305W Triple Output PSU provides a high level of power at a very affordable price.

By combining switch-mode pre-regulation with linear post-regulation, performance levels comparable to an all linear design have been achieved. The EX-R series provides much higher precision by incorporating four-digit meters and switchable remote sensing. It still maintains the user-preferred simplicity of operation, making it ideal for bench-top power supply users.

The EX-R series combines high frequency switch-mode pre-regulation with linear post-regulation to offer performance that is nearly equivalent to an all-linear design. It features excellent line and load regulation, low noise, and impressive transient response.

The units design features separate voltage and current meters on each main output, providing a resolution of 10mV and 1mA. This fixed resolution ensures accurate readings without the confusion of auto-ranging 3 or 3½ digit meters where the decimal point position shifts with changing readings.

Each main output includes a switch that can enable or disable the remote sense terminals. Remote sensing is essential for precise load regulation and accurate metering of load voltage. Some power supplies do not have remote sense, which can lead to misleading regulation figures. Each main output also has a DC on-off switch, allowing for voltage and current settings to be checked before connecting the load. The EX354RT incorporates a third output fully variable between 1.5V and 5.0V with a fixed current limit of 5A. The set voltage can be measured at the press of a button using the digital meters.

Multiple outputs can additionally be controlled independently, a feature that is often missing in many power supplies. Each main output supports constant voltage or constant current mode, with automatic crossover and mode indication. It also provides coarse and fine voltage controls, while the current control allows for precise adjustment of low current levels.

The power supply comes with TTi designed output terminals that can accept 4mm safety plugs with rigid insulating sleeves, fork connectors, and bare wires, providing enhanced connection flexibility.
