Precision with Simplicity
The new EL-R series has been developed from the top selling EL series. By adding four digit meters and switchable remote sensing, the EL-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer.
Eight models are offered including single, dual and triple outputs and covering a power range of 30 watts up to 130 watts.
-
Single outputs, 30V/1A, 18V/3.3A, 56V/1.1A, 15V/, 30V/3A
-
Single, dual or triple outputs, 30V/2A
-
Independent digital voltage and current meters for each output with 4 digit resolution
-
Switchable local or remote sensing
-
Constant voltage or constant current operation
-
Variable 1.5 - 5.0V auxiliary output at 2A (EL302RT)
-
Compact design uses less bench space
-
Silent fan-free cooling
-
DC output switches, automatic mode indication
-
RS232 or USB controlled models available (30V/2A single)
