Introduction; Specification - Aim-TTI EX354RD Installationsanleitung

The EX354RD and EX354RT 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. Remote sense
terminals are provided so that good regulation can be maintained across remote loads at high
current.
The EX354RD has two independent and isolated outputs each with a 0 to 35V, 0 to 4A capability.
The outputs operate in constant voltage or constant current mode with automatic cross-over and
mode indication. Each output has its own on-off switch. Where higher voltages or currents are
required the outputs can be wired in either series or parallel to provide voltages up to 70 volts or
currents up to 8 Amps.
The EX354RT has, in addition, an Auxiliary 'logic voltage' output with a 5A current capability. To
reflect the increasing usage of low-voltage logic devices, this output can be preset between
1.5 volts and 5 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-R 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.
The EX-R 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.
