TTI EX series
EX series - high power at low cost                                                                                            
The EX series provides high levels of power at surprisingly low cost. The attractive case style is highly compact using the minimum of bench space. The fan-less design provides silent operation. The low weight makes them easy to move about.
Mixed-mode regulation
The EX series combines switch-mode pre-regulation with linear post-regulation to provide performance comparable with an all linear design. Excellent line and load regulation is matched by low noise and good transient response. High power efficiency makes fan cooling unnecessary.
Constant voltage or constant current
The main outputs 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.
Low voltage auxiliary output
The new EX354Tv incorporates a third output fully variable between 1.5V and 5.0V with a fixed current limit of 5A. The set voltage can be measured using the digital meters.
Simultaneous digital metering
The EX series incorporate 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.
Single. dual or triple outputs
EX series units are available in single. dual or triple output versions. The EX354D. for example. has two independent and isolated outputs each with a 0 to 35V. 0 to 4A capability. The outputs can be wired in either series or parallel to provide voltages up to 70 volts or currents up to 8 amps. The EX354Tv has an additional low voltage auxiliary output with a 5A current capability. This output is fully variable between 1.5V and 5V and can be measured using the digital meters.
Safety and reliability
The EX series has been designed to meet the stringent requirements of relevant IEC standards for safety and EMC. All outputs are intrinsically short circuit proof. and are protected against external voltages and reverse currents
