AIM-TTi EL302RT Triple Output Linear DC Power Supply, 30V/2A, 30V/2A, 5V 2A, 130W PSU

AIM-TTi EL-R Series
The new EL-R series has been developed from the top selling EL series. By adding four digit meters and switchable remote sensing, the EL-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer. Eight models are offered including single, dual and triple outputs and covering a power range of 30 watts up to 130 watts.

• Single outputs, 30V/1A, 18V/3.3A, 56V/1.1A, 15V/5A, 30V/3A
• Single, dual or triple outputs, 30V/2A
• Independent digital voltage and current meters with 4 digit resolution
• Switchable local or remote sensing
• Constant voltage or constant current operation
• Variable 1.5 - 5.0V auxiliary output at 2A (EL302RT Triple Output)
• Compact design uses less bench space
• Silent fan-free cooling
• DC output switches, automatic mode indication
• RS232 or USB controlled models available (30V/2A single)

Simplicity in use
EL-R series power supplies use classic analog controls for voltage and current. The large and bright displays have a fixed resolution to avoid confusion. Pre-set voltage and current levels are shown when the DC output switch is turned off. Remote sense is available when needed but is disabled by setting the switch to Local.

Linear regulation
All EL-R series models* use true linear regulation for the best possible performance. Excellent line and load regulation is matched by very low output noise and good transient response.

Four digit meters
The EL-R series incorporates separate voltage and current meters on each main output with a resolution of 10mV and 1mA. The fixed resolution avoids the misinterpretation of readings that can occur with auto-ranging 3 or 3½ digit meters where the decimal point position moves as the reading changes.

Remote Sensing
Each main output incorporates remote sense terminals that can be enabled or disabled at the flick of a switch. Remote sensing is essential for maintaining precise regulation at the load and true metering of the load voltage. Many other power supplies omit remote sense, and quote regulation figures that could never be achieved in practice.

DC output switches
Each main output has a DC on-off switch. This enables voltage and current settings to be viewed before the load is connected and allows multiple outputs to be controlled individually. Surprisingly, many power supplies omit this essential feature.

Constant voltage or constant current
Each main output can operate in constant voltage or constant current mode with automatic crossover and mode indication. Coarse and fine voltage controls are provided. The current control is logarithmic enabling low current levels to be set accurately.

Silent cooling
All EL-R series models use convection cooling and are entirely free of fan noise.

Safety binding-post terminals
EL-R series power supplies are fitted with the new TTi designed output terminals. These can accept a 4mm safety plug with rigid insulating sleeve, a requirement specified by an increasing number of laboratories for safety reasons. However, unlike the 4mm safety sockets used on some other products, the new TTi terminals can also accept fork connectors or bare wires, giving maximum connection flexibility.
