<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 />
