(released position) when the instrument is overloaded or in constant current mode then beeper is ON along with CC LED is ON. Beeper can be disabled by pressing this switch. +/ - Terminals: These are the output terminals. The load is applied across these terminals. User Manual PSD3205X...
Fan: Low noise fan cools the instrument. The speed of the fan depends on the temperature of the internal heatsink. Fan maintains the temperature of instrument, when over temperature condition occurs. User Manual PSD3205X...
Operating Instructions General Information The logical front panel layout of PSD3205X ensures rapid familiarization with the various functions. However, even experienced operators should not neglect to carefully read the following instructions, to avoid any operational errors & to be fully acquainted with the instrument when later in use.
Description Output PSD3205X can either be used as a constant voltage source with current limiting or as a constant current source with voltage limiting. The change of mode occurs sharply at the crossing of the voltage and current settings. Fig. 3 shows the output ranges.
