EX-R Series DC Supplies: Mixed-mode Regulation, Silent Cooling*

Mixed-mode regulation

Mixed mode icon The EX-R series combines high frequency switch-mode pre-regulation with linear post-regulation to provide performance that comes close to that of an all-linear design. Excellent line and load regulation is matched by low noise and good transient response.

Constant Voltage / Constant Current

Constant Voltage / Current icon Each main output 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.

Silent cooling *

Silent cooling icon Most EX-R series models use convection cooling and are entirely free of fan noise. * The highest power density models, EX2020R and EX4210R, use an intelligent fan for cooling.

Simplicity in use

Analogue Controls icon EX-R series power supplies use classic analogue controls for voltage and current. The large and bright displays have a fixed resolution to avoid confusion. Preset voltage and current levels are shown when the DC output switch is turned off. Remote sense is available when needed but is disabled by setting the switch to Local.
