Lab power supply adds variable output
for free
Top-selling 300W triple-output laboratory power supply is replaced with a new model that incorporates a fully variable auxiliary output - at no extra cost.
TTi (Thurlby Thandar Instruments) has replaced its top-selling EX354T 300W triple-output laboratory power supply with a new model that incorporates a fully variable auxiliary output The new EX354Tv is a mixed-mode regulated power supply with dual outputs of 0 to 35V at 0 to 4A

The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
The third output is now continuously variable between 1.5 and 5.0V at currents of up to 5A, replacing the fixed 3.3/5V auxiliary output of its predecessor.
A push-to-measure button allows the right-hand display to show the settings for the auxiliary output, enabling the voltage to be set accurately without the need for an external meter.
The new model is also fitted with TTi's new safety binding post terminals.
These can accept fixed-shroud 4mm plugs, as required by some organisations on safety grounds, whilst retaining the flexibility to accept fork connectors or bare wires.
The mixed-mode regulation used on the EX series of power supplies involves power-factor corrected switch-mode pre-regulation followed by a linear final regulator.
This system achieves much better output noise and transient response figures than those of conventional switch-mode regulated units.
Despite its high total power, which is in excess of 300W, the EX354Tv uses fan-free silent convection cooling and is highly compact, measuring only 290 x 160 x 195mm.
The new model reflects the increasing use of low-voltage circuitry and the move away from standard operating voltages in most areas of electronics.
The price of the EX354Tv remains at GBP 438 (plus VAT), unchanged from that of the model that it replaces.
