Aim-TTi EX4210R Power Supply 0-42V/0-10A

The Aim-TTI EX4210R is a part of the EX-R series which has similar features to the EL-R series but uses mixedmode regulation to offer power from 175 watts up to 420 watts.

Full details of the EX-R series are included within this brochure

The new EX-R series has been extended by incorporating models from the best selling EX series. By adding four digit meters and switchable remote sensing, the EX-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer. Six models are offered including single, dual and triple outputs and covering a power range of 175 watts up to 420 watts.

Mixed-mode regulation

The EX-R series combines high frequency switch-mode pre-regulation with linear post-regulation to provide performance that comes close to that of an all-linear design. Excellent line and load regulation is matched by low noise and good transient response.

Four digit meters

The EX-R series incorporates separate voltage and current meters on each main output with a resolution of 10mV and 1mA (10mA on higher current models). 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 a practice. N.B. A 2 metre length of a 24/0.2 wire pair has a resistance of around 0.1 W. For a 5V load drawing 3A the metering error without remote sense would be 0.3V and the effective full current load regulation would be around 6%, against a quoted figure of perhaps 0.01% for the power supply itself.

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

Most EX-R series models use convection cooling and are entirely free of fan noise. * The highest power density models, EX2020R and EX4210R, use an intelligent fan for cooling.

Safety binding-post terminals

EX-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.
