Description produit

The EX354D and EX354T provide high levels of power (up to 305 watts) in a compact and attractive case style. High resolution controls allow precise setting of voltage and current levels which are indicated on accurate and legible digital meters. Excellent line and load regulation are matched by low noise and good transient response. High power efficiency ensures that the unit remains cool without any fan noise.

The EX354T has, in addition ‘logic voltage’ output with a 5A current capability. This output can be Selected between 5 volts or 3.3V volts via a front panel control. The total power capability is 280 watts for the dual supply and 305 watts for the triple.

The EX series incorporates separate digital voltage and current meters on each main output. The meters use bright 14mm (0·56”) LED displays and have an update rate of 4 per second providing near instantaneous response. Simultaneous metering of voltage and current provides accurate information “at a glance” and avoids any possibility of misinterpretation. When an output switch is set to “off”, the current limit setting is displayed enabling conditions to be set before the load is connected. With the right-hand main output off, the right-hand meters can be used to momentarily display the preset Auxiliary voltage and current limit.

To reflect the increasing usage of low-voltage logic devices, the third output of the EX354T can be switched between 5V and 3.3V.

The EX series has been designed to meet the stringent requirements of relevant IEC standards for safety and EMC, including harmonics emissions. All outputs are intrinsically short circuit proof, and are protected against external voltages and reverse currents.
