ABB SV/S 30.640.5 is a bus power supply that generates the 30 V DC system voltage for a KNX / ABB i-bus line, with the line choke built in. It is a modular DIN-rail component (MDRC) four modules wide. It is a KNX device in its own right: diagnostics are reported through ETS communication objects and status is shown on front LEDs.
SV — Spannungsversorgung, ABB’s designation for a bus power supply.
S — Reiheneinbau / MDRC, modular DIN-rail mounted.
30 — 30 V DC bus output.
640 — rated output current in milliamps.
.5 — version within the family.
GH Q631 0048 R0111 — ABB article reference carried on the device label.
Function: KNX / ABB i-bus system power supply with integrated choke. Bus output: 30 V DC, rated 640 mA. Additional output: 30 V DC without choke, for a second line via a separate external choke. Overload current: 0.9 A. Short-circuit current: 1.4 A. Output protection: short-circuit and overload protected. Power-failure buffering time: 200 ms. Diagnostics: advanced diagnostics with ETS communication objects; LED status display. Unit Quantity: 1 Pc.
Mounting: DIN rail, modular DIN rail component (MDRC). Width: 4 division units (modules).
SU/S30.640.x is the uninterruptible version, which maintains the bus from a connected battery during a mains failure. Within the SV family, 160 mA, 320 mA and 640 mA units carry different current ratings. SV/S30.640.5.1 is a separate catalogue item with its own article number and ETS application.
Bus output is 30 V DC rated 640 mA, with overload current 0.9 A and short-circuit current 1.4 A, plus a second unchoked 30 V DC output.
It is a four-module wide modular DIN-rail component (MDRC).
Advanced diagnostics through ETS communication objects, with LED status display and 200 ms power-failure buffering.
