By adding four digit meters and switchable remote sensing, the EX-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer.Six models are offered including single, dual and triple outputs and covering a power range of 175 watts up to 420 watts.EX-R Series - Mixed-mode Regulated Precision Laboratory Power SuppliesMixed-mode regulationThe 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.Four digit metersThe EX-R series incorporates separate voltage and current meters on each main output with a resolution of 10mV and 1mA (10mA on higher current models). The fixed resolution avoids the misinterpretation of readings that can occur with auto-ranging 3 or 3 digit meters where the decimal point position moves as the reading changes.Remote SensingEach main output incorporates remote sense terminals that can be enabled or disabled at the flick of a switch. Remote sensing is essential for maintaining precise regulation at the load and true metering of the load voltage. Many other power supplies omit remote sense, and quote regulation figures that could never be achieved in a practice.N.B. A 2 metre length of a 24/0.2 wire pair has a resistance of around 0.1 W.
