■ Overview
By combining a SITOP power supply unit with a DC UPS module
and with at least one 24 V battery module or a maintenance-free
SITOP UPS500S (optionally with extension module), longer
power failures can be bridged without any interruption.
This combination is used, for example, in machine tool manufac-
ture, the textile industry, all types of production lines and filling
systems, and in conjunction with 24 V industrial PCs. This pre-
vents the negative effects which often result from power failures.
For SIMATIC PC this implies a failsafe shut down of all current
applications, as well of the operating system.
For “NON-STOP” use in the event of power failures, Siemens
offers the following uninterruptible power supplies:
• DC UPS 6 A
• DC UPS 15 A
• DC UPS 40 A
and the following battery modules:
• 1.2 Ah (contains lead-acid batteries with corrosion-resistant
lead-calcium, high-capacity grid plates and fiberglass mat)
• 3.2 Ah (contains lead-acid batteries with corrosion-resistant
lead-calcium, high-capacity grid plates and fiberglass mat)
• 7 Ah (contains lead-acid batteries with corrosion-resistant
lead-calcium, high-capacity grid plates and fiberglass mat)
• 12 Ah (contains lead-acid batteries with corrosion-resistant
lead-calcium, high-capacity grid plates and fiberglass mat)
• 2.5 Ah (contains “high-temperature battery” lead-acid type)
The maintanance-free DC UPS modules with capacitors as
energy storage are particularly suitable for operation in high
ambient tamperatures:
• SITOP UPS500S (DC UPS basic unit 15 A 2.5 kWs)
• SITOP UPS500S (DC UPS basic unit 15 A 5 kWs)
Optionally for increasing the buffer time:
• SITOP UPS501S (capacitor module 5 kWs)
