TTi has upgraded its well known EX354D bench power supply to improve its precision. The new model, the EX354RD, has 4-digit meters for both voltage and current along with switchable remote sense terminals.
The EX354RD has two independent and isolated outputs of 0-35 V at 0-4 A. Separate meters are provided for voltage and current on each output, providing resolutions of 10 mV and 1 mA, respectively. The outputs can be wired in series or parallel to give a maximum voltage of 70 V or a maximum current of 8 A.
Local or remote sensing can be selected by front-panel switches, the latter providing perfect regulation and accurate metering at the load regardlesss of connection lead lengths
The EX354RD uses mixed-mode regulation incorporating linear final regulation to give low output noise and good transient response. The outputs can operate in constant-voltage or constant-current mode with automatic crossover.
The new power supply incorporates the latest TTi safety binding post terminals. These will accept 4 mm fixed shroud plugs: a mandatory safety requirement for an increasing number of organisations - but can also accept fork connectors or bare wires, giving maximum flexibility.
Unlike most other bench power supplies of this power level, the EX354RD is silent in operation because it uses convection cooling throughout. It is highly compact, measuring 260 x 160 x 320 mm (10.2 inches wide x 6.3 inches high x 12.6 inches deep), and weighs only 4.3 kg (9.5 lb).
