DC – UPS Systems for Safety Relevant Installations

With their modular construction, the latest DC – UPS systems in the GTLB/GTPB series from Zentro Elektrik expand the existing comprehensive range of DC – UPS systems for supplying power to safety relevant installations.
The AC/DC systems in standby parallel mode are designed for outputs
from 250 Watt up to 600 Watt and fitted with batteries at the customer’s request. Additional DC/DC converters can be added to the system if more output voltages are required.
A battery control and monitoring module allows to control the charging current and temperature control of the charge closing voltage.
Over and above this, numerous monitoring and control signals are provided via relays, LED’s or potentiometers. A signal relay, for example,
if the charging voltage fails, to switch off the battery on it reaching the closing discharge voltage, to give advance warning of reaching closing discharge voltage with an additional adjustable threshold or individual limitation of the battery charging current to prolong battery life, and
many more. LED displays and adjustable potentiometers provide for comprehensive signalling and the ability to adjust the maximum charging voltage or the defined point of battery switch-off.
