SITOP Electronic Diagnostic Module
●The SITOP Electronic Diagnostic Module is specially tailored to the characteristics of switched-mode power supplies. The electronics permit brief current peaks and switch longer overloads off-circuit, even on long thin cables and with earth leakages in which the current is limited by high resistance. In this case the circuit-breakers do not trip, or they trip too late, even if the power supply could deliver the current. The selectivity module reliably disconnects the faulty load circuits, and the supply to the other loads continues with absolutely no interruption so that total failure of the plant can be avoided. The fault is output via a common signaling contact and indicated by an LED on the relevant load circuit; in this way, the fault can be quickly localized and downtimes are minimized.
●Features:
● Current Setting Range Between 0.5 and 3 A for Each Load Circuit
● Remote Reset for Switching Channels Back in that Have Been Disconnected From a Central Location
● Reset Button for Each Channel
● Manual Disconnection and Switching in of Individual Channels Via a Reset Button, e.g for Commissioning Purposes (on SITOP Select Via a Fuse)
● Optimized Display of Operating Status Via 3-Color LED with Additional Display of a Manually Disconnected Channel
● Power-Up Sequence Can Be Set Via DIP Switches; Switches Indicate the Setting
● Cover on Potentiometers and DIP Switches Prevents Undesired Parameter Setting, Sealing Possible
●Specifications:
● Ambient Temperature: –20 to 70°C
● Dimensions (W × H × D): 30 × 80 × 100 mm
