Maintenance-free DC UPS - bridging power failures with supercaps
With the maintenance-free DC-UPS from FEAS, you protect your systems from brief power failures and peac loads
These capacitor-based DC UPS of the SSE series from FEAS, also called buffer modules, are suitable for bridging short-term power failures, peak loads or switching operations. The required energy is stored in internal super capacitors. Thus, these uninterruptible power supplies (UPS) are absolutely maintenance-free. A rechargeable battery is not installed. Fully encapsulated in an aluminium housing, the capacitor-based UPS (buffer modules) are characterised by vibration resistance and suitability for industrial and tropical environments.
UPS with battery for longer downtimes can be found under the product category "DC-UPS - with accu".
Maintenance-free DC-UPS - for a wide range of applications
Choose a buffer module that suits your application:
► Output voltage 12VDC 24VDC or 48VDC
► with AC or DC input / with or without integrated power supply unit
► adjustable buffer voltage
► Boost function up to 200%
► with typical buffer times between 4s and 30min
► Remote monitoring (power failure, state of charge, temperature, overload)
► Installation on DIN rail or wall mounting
Capacitor-based DC UPS - how they work
The DC UPS with capacitor (buffer module) is connected in parallel directly into the regulated DC voltage circuit at any point or it is used for selective protection of critical loads. As long as the DC power supply provides the voltage, this UPS (buffer module) stores energy in buffer capacitors (super capacitors or ultra capacitors). If the mains voltage fails, the UPS takes over the load current for a certain time. This allows, for example, processes to be terminated in a defined manner or process data to be saved.
Maintenance-free DC-UPS - output voltage 12VDC, 24VDC, 48VDC
First select the required output voltage of your buffer module (12VDC, 24VDC or 48VDC). You will get a list of all buffer modules from FEAS.
