Vysokonapěťový zdroj HV 5000T

HV5000T is a sta­bi­li­sed high vol­tage sup­ply ran­ging 0–5000V (opti­o­nally 1kV/ 2kV / 3kV/ 4kV) with current limi­ting, indi­cati­on of out­put current and vol­tage, and current limi­ting sta­tus indi­ca­tor (LED, relay).

Power Sup­ply and Start
The devi­ce is fed by +230V (± 10%) DC power sup­ply; high vol­tage (HV) is pre­sent on the out­put ter­mi­nals only if the START but­ton is in the swit­ched-on posi­ti­on (loc­king but­ton).

Current Limi­ting Fea­tu­re
Current limi­ting sta­tus is detec­ted and indi­ca­ted by the devi­ce in two possi­ble ways:
Opti­on A (manu­factu­rer setup)
Relay ope­ra­tes in a tem­po­ra­ry mode, i.e. when current limi­ting is in use or not used relay con­tacts RLC —- RL1 or RLCRL2 clo­se or open, respecti­ve­ly. At the same time REL indi­ca­tor lights up and vol­tage appears (+24V aga­inst GND) on ter­mi­nal P (disap­pea­ring from ter­mi­nal N at the same time). After the current limi­ting is no lon­ger used all the abo­ve descri­bed out­puts return to the­ir sta­te as befo­re the current limi­ting. AUX indi­ca­tor lights on and rema­ins ligh­ted even after current limi­ting. This ser­ves as a long-term indi­cati­on of the fact that current limi­ting had been used (the fea­tu­re can be used for instan­ce for long-term observati­on etc.). AUX can be tur­ned off by pres­sing the RES but­ton (or it can be tur­ned off exter­nally by clo­sing a con­tact between the RES and +5V ter­mi­nals).

Opti­on B (inter­nal setup needs to be chan­ged — jum­per). This opti­on is oppo­si­te to the pre­vi­ous one, i.e.:
Relay ope­ra­tes in a per­ma­nent mode, i.e. when current limit is in ope­rati­on or out of ope­rati­on relay con­tacts RLC —- RL1 or RLCRL2 clo­se or open, respecti­ve­ly. At the same time REL indi­ca­tor lights up and vol­tage appears (+24V aga­inst GND) on ter­mi­nal P (disap­pea­ring from ter­mi­nal N at the same time). After the current limit is no lon­ger in ope­rati­on, the relay rema­ins clo­sed until it is reset by pushing a but­ton or by apply­ing exter­nal sig­nal. AUX indi­ca­tor lights up only when current limi­ting is in use and swit­ches off imme­di­a­te­ly after the current limi­ting is no lon­ger in use.
