These Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
The navigation buttons have the following functions:
|◄ takes you back to the beginning of the current tour
◄ is the same as your browser back button
▲ takes you up a level in the hierarchy
► steps forward to the next page
The drop-lists give another way of accessing the same pages
shows and hides a map of the structure of the tour with links to each page.

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