Maintenance-free UPS does away with battery replacement

Maintenance-free UPS does
away with battery replacement
New uninterruptible DC power supply
with capacitor technology
Uninterruptible power supplies usually store
electrical energy in rechargeable lead-acid
batteries. The temperatures inside a control
cabinet, however, shorten the service life of
the battery substantially, making battery replacement a routine necessity – for instance,
once a year at a cabinet temperature of 40 °C.
Not so in the case of the innovative DC UPS
from SITOP. Capacitors with a long service life
mean you don‘t have to replace batteries,
which is how the totally maintenance-free
UPS pays for itself within a short time.
As no hydrogen is emitted even in the event
of a fault, there is no need for ventilation of
the site. The much shorter charging times also
mean fast availability following a power
failure. The 24 V DC UPS comes in degree of
protection IP65 for distributed use, and in IP20
for DIN-rail mounting. This means it is possible
to back up data after a power failure, and to
safely shut down a PC-based control application, for example.
SITOP UPS500
Answers for industry.
The advantages at a glance
Totally maintenance-free DC UPS with high-capacity
double-layer capacitors
• Modularly cascadable for DIN-rail mounting:
SITOP UPS500S basic unit 24 V/15 A with integral
2.5 or 5 kW energy storage, combinable with up to
3 UPS501S expansion modules (5 kW)
• SITOP UPS500P 24 V/7 A in degree of protection
IP65 for distributed use, e.g. on support arms
• Long-life capacitors eliminate battery replacement: After 8 years, the UPS500 still has 80%
of its rated capacity at an ambient temperature
of 50°C
• Totally maintenance-free
• No ventilation of the mounting location is necessary (VDE 0510 Part 2 / EN 50272-2)
• Backup is available again quickly
• Safe shutdown and correct restart of SIMATIC PCs
• Software tool supports further processing and
response of the PC: www.siemens.com/sitop-ups
