Power supply for switch’s coils ZCW-1


After switching on, on device display appears last voltage setting. Change of output voltage is performed by keys ↑ or ↓. By pushing MENU button, options: GENERATION TIME, VOLT. INCREASE, VOLT. DECREASE are available, user can choose option using keys ↑ and ↓. Using MENU button and keys ↑, ↓ user can set new values. By pressing MENU once again, new values are stored, ESC key abandon settings.
Button START/STOP begins/stops voltage generation. During generation, changes in MENU options are not possible. If voltage setting is displayed, user can activate automatics mode “A” by pushing ESC button. In “A” mode, user can change voltage (using ↑ or ↓) by percentage step value (according to settings in options VOLT.INCREASE, VOLT.DECREASE). Value of changed voltage and percentage change of rated voltage are displayed on LCD screen.
TIME GENERATION option allows setting of continuous operation or stop generation after determined period (1 s to 60 s). Power supply is protected against overload current (>2,5 A) by generation switch off (LED signalling >I).


Power supply for switch coils is designated for switches operation testing with reduced and elevated supply voltage.
