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.

Auxiliary low-voltage output
The EX354Tv incorporates a third output variable between 1.5V and 5.0V with a fixed current limit of 5A. The set voltage can checked using the digital displays.

 
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.

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.
