QUINT-DC-UPS uninterruptible power supply units with long-life lead-acid batteries provide long buffer times at high currents. Even in the event of a longer supply voltage failure, the units ensure that all connected devices continue to operate without interruption.

The devices have a narrow and uniform design, which makes them ideal for use on the DIN rail where space is limited. In addition, short wiring paths ensure order and clarity in the control cabinet.

The high level of availability and the particularly long service life of the battery modules are achieved through professional battery management. An automatic presence check (every minute) and electronic over current protection ensure the battery modules are ready to operate at all times. Power is therefore available in the event of an error and the service life of the battery module is maximized.

The actual state must be determined quickly so that the right decision can be made in an emergency. Optimum signaling is thus required for maximum system availability. Three floating PDT contacts and three LEDs are provided for function monitoring, which indicate all the operating states clearly.

So that relay signaling is more reliable and more durable than before, an additional positive supply output has been provided. The contact, which is current-limited and resistant to continued short circuits, is located next to the relay connections and enables easy bridging. In the event of wiring errors, the short circuit protection prevents any welding of the relay contacts. This ensures that the user can rely on an OK signal. Even in the event of connection errors, currents remain below 100 mA, which prevents damage to the relay contacts.

A system is switched off after a specific time that can be set on the device or by an external signal. No additional installation is required for shutdown. In addition, ready-to-use plug-in bridges minimize the installation time.

The connected devices can be divided into buffered and unbuffered loads using the isolated input. This extends the buffer time, which depends on the output current. If only critical devices are protected using fuses, smaller battery modules can be used that save money and space in the control cabinet. In addition, the isolated input protects the connected devices against errors in the internal network.
