Sv-2/dr2 Special Offer"

Manufacturer-number: SV-2/DR2 - EIB KNX Power Supply SV-2/DR2 2500 mA/DC The EIB KNX power supply SV-2/DR2 serves to supply EIB KNX lines. The switch-mode power supply has a nominal current of 2500 mA and disposes of a voltage tap that can be adjusted from 22.5 to 29.5V/DC (potentiometer preset to 29.5V for EIB KNX). The delivery includes 1x power supply SV-2, 2x current limiter module SB640 and 2x choke to supply max. 2 EIB KNX line (2x 640mA). As far as the structure is concerned, this is the same as extending an existing EIB KNX facility by one line using the unchoked 29V-raw voltage output of the 640 mA power supply. Therefore a choke is required. The 29V raw voltage (unchoked) is transmitted from the power supply SV-2 via the current limiter module to the choke. The choke serves to generate the frames and prevents short circuit of the data frames on the line. The EIB KNX bus voltage can now be collected via bus terminal at the lower side of the choke. Advice: The module SB640 serves to limit the current for the power supply of EIB KNX lines (building automation) using KNX compliant power packs that can provide more than 640 mA. This current has to be limited to 640 mA to meet the EIB KNX standards. To achieve this special features and an electronic fuse have been integrated that limit the line current to 640 mA. In addition to that an LED shows the current supply status: LED off: no supply voltage LED permanent green: power supply of EIB KNX line is OK, line current is under 600 mA. LED flashing green: voltage of power pack is OK, EIB KNX line is OK the line current is just below the maximum admissible values, the line is seriously used to capacity. LED flashing red: voltage of power pack is OK, EIB KNX line is overloaded or shorted.
