<strong>SITOP</strong> <strong>power</strong><br />
Introduction<br />
Overview of product families<br />
<strong>SITOP</strong> DC UPS<br />
The DC UPS modules provide optimum protection against<br />
longer <strong>power</strong> failures. DC UPS modules and battery modules<br />
expand <strong>SITOP</strong> <strong>power</strong> supply units with 24 V output voltage into<br />
uninterruptible <strong>power</strong> <strong>supplies</strong> with a rated output current up<br />
to 40 A. The transition from <strong>power</strong> supply mode to buffered<br />
mode is absolutely interruption-free. The DC UPS modules are<br />
provided as standard with all required protection and monitoring<br />
functions, thus providing high availability. The integral battery<br />
management function guarantees a long service life for the<br />
maintenance-free battery modules. Status messages concerning<br />
the operational readiness, battery status and battery lines are<br />
signaled by LEDs and floating contacts. The compact 6 A and<br />
15 A DC UPS modules can also communicate via an interface,<br />
thus permitting simple integration into PC-based systems.<br />
and tested<br />
Tried and tested<br />
The <strong>SITOP</strong> range of <strong>power</strong> supply units has proven its reliability<br />
for many years already. The units offer graded performances<br />
with output currents from 2 A to 20 A and from 10 A to 40 A for<br />
single-phase and three-phase incoming <strong>supplies</strong> respectively.<br />
Thanks to the simple handling and numerous certifications, the<br />
24 V <strong>power</strong> supply units are also suitable for export-oriented<br />
use in all standard automation engineering applications. And<br />
should it be the case that the <strong>power</strong> supply conditions are<br />
unreliable in a global application, the proven <strong>SITOP</strong> <strong>power</strong><br />
<strong>supplies</strong> can of course also be combined with the DC UPS<br />
modules.<br />
The facets<br />
The <strong>SITOP</strong> <strong>power</strong> supply units also cover individual <strong>power</strong><br />
supply requirements - whether standard industrial applications,<br />
extreme ambient conditions, or unusual output voltages. The<br />
<strong>SITOP</strong> variants include some true all-rounders:<br />
<strong>SITOP</strong> <strong>power</strong> 0.5: the mini devices with a width of only<br />
22.5 mm are the narrowest in the <strong>SITOP</strong> family and are therefore<br />
particularly suitable for supplying low-voltage switchgear.<br />
<strong>SITOP</strong> <strong>power</strong> flexi: unlimited variety thanks to a variable output.<br />
The innovative circuit concept permits flexible setting of the<br />
output voltage between 3 V and 52 V. Special voltages can<br />
therefore also be covered by a standard device.<br />
<strong>SITOP</strong> <strong>power</strong> dual: the electronics supply for the switchgear<br />
cabinet. The DIN rail device is industry-compatible and has<br />
two 15 V outputs. For example, for electronic loads to be<br />
supplied with ±15 V.<br />
<strong>SITOP</strong> <strong>power</strong> 24 V/2.5 A, 4 A and 10 A: the devices with<br />
universal input can be connected to 1-phase AC voltage<br />
networks as well as to DC voltage networks.<br />
<strong>SITOP</strong> <strong>power</strong> 24 V/20 A: the 2-phase primary switched-mode<br />
regulator with 20 A rated output current is predestined for<br />
industrial networks with high AC voltages. The special widerange<br />
input allows connection to 3-phase networks with rated<br />
voltages between 500 V and 600 V.<br />
<strong>SITOP</strong> <strong>power</strong> AS-Interface: 2 primary switched-mode regulators<br />
are available especially for <strong>power</strong>ing the actuator/sensor<br />
interface: a 2.4 A version with 24 V DC input and IP65 degree<br />
of protection, and a 7 A version with wide-range input for AC<br />
and DC voltages.<br />
